industry.
A LEADER IN EXPERIENCE
Seldom are manufacturers
regular users of the products
they produce. Powervamp is the
exception. Our extensive
“hands-on” air show experience
gives us the technical edge in
the market.
A LEADER IN CUSTOMER
SUPPORT
Repeatedly, we outperform
major corporations many times
our size with our technical
knowledge, our customer care
and our rapid response
capability.
“
Since forming Powervamp almost 25 years ago, and
like anyone working in aviation for many years, I have
witnessed massive changes in every area – from the
weather and its effects on equipment design to the
quality standard and high levels of power required to run
today’s AC and DC aircraft. The performance demands
on equipment have never been higher, and with them
comes the need for outstanding product reliability
and support.
No matter what size a manufacturing business is, it is the
product quality, product performance and product
support that create and build its reputation. As a
business grows, it is essential that management invests in
the direct and indirect overheads of the business if it is to maintain that reputation and
competitive edge in the market.
Since the beginning, Powervamp product quality and customer support have been the key
to our growth, with repeat business confirming the success of our strategy. Maintaining our
reputation and developing new products have demanded continuous investment in every
area. That includes factory space, production staff, development engineers, expensive test
equipment, a rapidly expanding installation and service team and a growing administration
and management team, all required to run the business and support the customer.
As a private company owned by its directors, Powervamp is not constrained by today’s
corporate reporting culture or driven by the need to maximise shareholder returns at the
expense of product quality or service. For us, it is the customer who is always first. That is
how it was when I started the business in 1993, that is exactly how it is today!
From our main 25,000sq ft factory near Luton, north of London, Powervamp now sells to
more than 60 countries through its agents and distributor network, with multiple
installations at major airlines and the world’s busiest airport. Our range of electric solid state
AC and DC GPUs, including Powervamp’s advanced 28V DC hybrid GPU, is recognised for its
performance and quality.
We are recognised as the UK’s sole designer and manufacturer of 400 Hz solid state
frequency converters and DC power carts delivering a major reduction in CO2 emissions at
airports with our ‘green’ solutions. Our strong R&D team and software engineers ensure we
retain complete control over quality, spares and customer support.
In choosing Powervamp, I can guarantee that you will be entering into a long-term
relationship with the company and its directors and staff, where none of us forget that your
satisfaction is the passport to our continued sales and growth.

SELECTING THE CORRECT AIRCRAFT START UNIT
i DC RAMP CARTS and DC PORTABLE AIRCRAFT START UNITS
Selecting the correct model of aircraft start unit can
sometimes be a confusing task. It’s essential that the unit
you select for starting turbines and for providing
sufficient power for pre-flight checks, also provides the
performance and product lifespan that you need.
The following checklist has been specifically designed to
assist Powervamp customers with their aircraft start unit
selection. And of course, Powervamp’s technical support
department or appointed distributors will also be
pleased to offer advice in helping you select the correct
GPU.
Will the GPU be used for programming/pre-flight
checks before spool-up?
Allow additional amp/hr capacity to
ensure a cool start.
✓ Recommended:
GPU 2400
Selecting the correct unit
Will the GPU be used for regular
avionics or maintenance work?
High discharge batteries designed for starting are not
designed for continuous powering. Consider a GPU with an
internal power supply or run our separate DC power supply
in parallel with the
pack.
✓ Recommended:
How many engine starts are required
before the GPU can be re-charged?
Remember: starts, pre-flights and line ops require amp/hr
capacity to maintain volts. More starts require more amp/hr
capacity and more weight, and therefore a larger size DC
battery cart.
✓ Recommended: Coolspool 410
Coolspool cart range
or GPU 1500/40 or
standard battery
pack in parallel with
one of our power
supplies
Is the pack for emergency use only?
A GPU with minimum capacity may be sufficient, as it is
unlikely to encounter intense usage.
✓ Recommended: GPU 1700
Will the GPU be used as the main
ramp/hangar GPU on multiple operations?
It’s best to extend
the GPU life with
extra amp/hr
capacity.
✓ Recommended:
Coolspool 130 or
260 ramp cart
depending on
aircraft size (for
extended battery
life)
Does the aircraft have tight upper avionic limits
that must not exceed 29–30 volts?
✓ Recommended: Coolspool 130, 260 or 410
with batteries configured to a nominal voltage of
26V DC instead of 28V DC
Is the requirement for line ops on regional/
commuter aircraft-typically ATR and Q400 aircraft?
In this case, there must be sufficient capacity to deliver
continuous ground power for 30-40 minutes
and to start a heavy turbine.
Is engine free turbine or shaft turbine/turboprop
or turbofan?
Longer spool-up times of shaft turbines will require more
amp/hr capacity.
✓ Recommended: GPU 1500/40 or GPU 1500/40 Twin
✓ Recommended:
Coolspool 410
(designed
for this
application)
Will the pack be carried on board?
You’ll need to consider the weight of the unit, but beware of
reducing weight at the cost of performance.
✓ Recommended: Coolspool 17
Is the GPU required for regular
compressor washing?
The battery will
need more frequent
replacement if using
an undersize pack.
✓ Recommended:
Coolspool 260
12
Is continuous DC power required for
maintenance or training?
Select a DC power supply. Ensure input circuit breaker is
rated to handle the maximum required DC output.
✓ Recommended:
PS30, PS50,
PS100
or PS300
NOTE
Selecting any portable GPU is not an exact science. It is a
compromise between weight, size, necessary performance,
recharge time, battery life and price. It should be noted that the
life of the GPU is affected by the depth of discharge each time
the GPU is used. The deeper the discharge each time, the
sooner the batteries will need replacing. It is preferable and
more cost effective to buy a GPU with maximum amp/hr
capacity.

28V DC RAMP CARTS
28V DC Ramp Carts
HIGHLY EFFICIENT, LOW-COST RAMP/HANGAR POWER
– THE 28V DC COOLSPOOL RAMP CARTS
The award-winning Coolspool range of
28V DC battery carts are a cost saving,
environmentally-friendly alternative to
diesel GPUs.
Where no AC power is present or noise
curfews prohibit use of diesel GPUs, they
are a highly efficient, low cost power
source – operating at a fraction of the
cost of a diesel GPU, yet able to deliver
the same power and turbine starting
output.
These large, new generation, powerful,
heavy-duty battery carts provide a
combination of instant high amperage
with pure DC wave form and full
mobility, low initial investment and
extremely low operating costs. Their
zero noise and zero carbon footprint are
important environmental considerations.
Coolspool 410: powering an ATR-72/600
With the price of diesel increasing and
stricter legislation on noise and CO2
emissions, the advanced technology
Coolspool battery cart range is the way
forward for regional and feeder airlines, FBOs
and ground handling agents under pressure
to reduce direct operating costs.
Powervamp’s large 28 volt Coolspool battery
cart GPUs are increasingly being used to
provide the smooth 28 volt DC power
required for pre-flight checks, avionics
programming or maintenance. They are ideal
for crew training, aircraft turnround/cabin
cleaning at remote airport stands (where
power can be required for anything from a
few minutes to several hours) or where noise
curfews or the lack of any electrical supply
prohibit any other method of powering the
aircraft’s DC systems.

28V DIESEL-BATTERY COMBINATION GPU
28V Mini Diesel (Hybrid)
Coolspool Hybrid 300
COMPACT, VERSATILE, CONVENIENT
– THE COOLSPOOL HYBRID 300
Powered by a 3-cylinder, water-cooled Kubota diesel engine,
fully Tier IV compliant, the Coolspool Hybrid 300 is designed to
provide continuous power for avionics and to start the engines
on all DC turbine and turboprop aircraft.
Coolspool users benefit from a compact unit, user friendly
controls and very low operating costs, with the further
advantage of low dBA signature and reduced CO2 emissions.
Normally, a diesel GPU four times the size of the Coolspool
Hybrid 300 is necessary to deliver the peak amperage for
starting large turbines.
The Coolspool Hybrid 300 achieves the same starting
performance using a 900cc (55 cu In) Kubota diesel engine
coupled to a powerful generator powering 3 x 100amp 28V DC
power supplies. These operate in parallel with a bank of high
discharge batteries that provide instant ripple free power for
turbine starting and aircraft loads exceeding 300 amps.
Coolspool Hybrid 300 is designed to start the turbines on all DC
aircraft. Typical power plant includes:*
DC regional jets and turboprop airline operations using PT6C-67, TPE 331-12,
RR Dart 356, RR AE3007A, PW121, PW127, PW150A, ALF 502, CF34B, BR710,
or power plants of a similar specification and those of all DC helicopters.
Features
l Large fuel tank: 14 hours run time at 50% load
l 300 amp continuous output from 3 x 100 amp paralleled modules
l Single phase 16 amp 115 VAC or 230 VAC output
l Designed for hangar use
l Comprehensive, easy-to-use, intelligent digital control panel
The Coolspool Hybrid 300 is suitable for all types of operation,
including offshore helicopter operations, FBO and maintenance
organisations and daily regional airline use. Where multiple
departures of large regional aircraft – such as the Q400 or
ATR – are scheduled, the Coolspool Hybrid 300 can be fitted
with Powervamp’s ‘PBS’ (Power Boost System). The PBS
sustains voltage during the critical initial start sequence on
large turboprop aircraft with shaft or free turbine engines,
thereby ensuring a fast, cool start while maximising battery life.
No other GPU delivers the versatility and convenience of
Powervamp’s Coolspool Hybrid 300. This compact and efficient
diesel GPU also provides single phase AC output to enable
ground staff to operate vacuum cleaners or other equipment
during night servicing.
In a hangar or confined space, the Coolspool Hybrid 300
engine can be shut down. A selector switch isolates the
generator and allows external 3-phase AC power to be
connected from a suitable utility supply. The full output from
the Coolspool Hybrid 300 is then available with the external
power source constantly maintaining the batteries in a full state
of charge.
Available in various configurations and in series production over
17 years, with sales to several armed forces, the Coolspool
Hybrid 300 is the civil version of Powervamp’s DC GPU. It is
designed for operators requiring versatile, standalone, high
output DC power at a fraction of the cost of a conventional
diesel GPU.

WORLD-LEADING GROUND POWER UNITS
– PERFORMANCE, RELIABILITY, EASE OF SERVICING
Powervamp’s range of tough,
competitively-priced hand-portable
aircraft start units and GPUs are
world-renowned for their performance,
reliability and ease of servicing.
The Twin Pack concept
– pioneered by Powervamp
Small size and low weight are important requirements
for hand-portable aircraft start units. There are times
when you need additional battery capacity and
performance, but you still want to retain the essential
benefits of mobility or hand-portability in your units.
The solution, pioneered by Powervamp more than 20
years ago and now adopted throughout the industry,
is to connect two aircraft start units in parallel by a
plug-in polarized heavy-duty cable, instantly doubling
the battery capacity for increased starting capability.
All twin units can be conveniently separated for ease
of transport, and are designed to be carried on board
for emergency power or turbine starting.
Using an optional second Nato plug lead set, the units
can be deployed individually, or connected together
where an aircraft requires a parallel start.

Originally developed in 2001 to provide continuous power for
avionics use and for starting medium sized helicopters and AirForce PT6 turbine EMB110 Bandeirante aircraft, the GPU 1500/40
only weighs 26kg (57lbs), yet incorporates an internal 40A
continuous 28V DC output using split 20A power supplies.
Each GPU is supplied with a power supply LED output monitor
for load monitoring and diagnostics, and can be re-charged via
its accessory port by any 24–28V DC aircraft power source,
including the aircraft 28V DC bus connector.
GPU 1500/40 TWIN
The modular design allows easy swap out and field servicing and
also allows two GPUs to be paralleled together, creating the GPU
1500/40 Twin.
The Twin is suitable for starting larger helicopters and business
jets where larger turbines or turboprop aircraft require higher
instant amperage and longer start cycles. It will deliver 80A
continuous output when connected to AC power and is ideal for
lengthy pre-fight checks.
The units are fitted with solid state voltmeter with ‘push to view’
button to monitor battery voltage. A spring-loaded output cover
ensures each unit is cleared for air transportation. They are
supplied with Nato plug lead set, input lead and heavy-duty
padded jacket.

DC POWER SUPPLIES
DC Power Supplies
30 TO 300 AMP POWER SUPPLIES:
COMPACT – RELIABLE – ESSENTIAL
Electronic flight decks, once the sacred
ground of the large corporate and wide
body, are now common to every type
and size of aircraft.
Powervamp, with its range of power
supplies from 30 to 300 amps,
manufactures units for all types of
aircraft from the Cessna 175 to the
largest of DC aircraft such as the ATR,
Embraer 145, Q400 and Saab 340.
Remaining ahead of the curve with the
faster speeds of the VLJs requires
private and corporate pilots to be
proficient in the use of their EFIS.
Practice and the need to update
software are two reasons why all aircraft
operators should own a reliable and
compact power supply, able to be used
for training, fault finding or software
updates.
Confirmation of Powervamp’s quality
and performance has been endorsed
by some of the world’s largest
manufacturers of private,
business and corporate jets who
have selected Powervamp power
supplies as their branded product
supplied to customers for software
updates and a source of DC power at
remote locations.
Powervamp’s first 28 volt 40 amp power
supply was produced in 1995 as a
solution to the problem of training police
observers on FLIR systems. Until then,
training involved expensive helicopter
flying hours or powering a FLIR system
with battery GPUs with limited power
duration.
Other manufacturers too have selected
Powervamp power supplies as the
chosen unit for their service support
teams. In every case, quality, reliability
and product support are key.

i SELECTING THE CORRECT POWER SUPPLY
When deciding on the size of power supply, operators should
consider the following:
Aircraft load fluctuation
If aircraft loads are likely to fluctuate, Powervamp strongly
recommends a power supply with a digital voltmeter.
Power demand fluctuating close to or above overload will
trigger a progressive automatic voltage shutdown which can
cause radio static and possible data loss. A digital voltmeter will
visually alert the operator to the situation.
Call for advice
For advice on selecting the correct power supply, call
Powervamp’s technical support department or appointed
distributors, who will be pleased to help you choose the right
model for your needs.
+44 (0)1934 643000
info@powervamp.com
All Powervamp power supplies are fitted with accurate digital
voltmeters. The larger units are fitted with digital ammeters to
give pilots and engineers an instant reading of the load as each
system is powered up.
Output limitations
Operators should be aware of possible power output limitations
at 110 volts where the mains circuit breaker rating may be
insufficient to allow maximum DC output. In this situation, the
anticipated output load will need to be checked against the
input amperage, which must be less than the circuit breaker rating.
Digital voltmeters
are included on all
Powervamp power
supplies
Typical power plant:
Arrius, Rolls-Royce 250, PT6A-27. Continental and Lycoming piston, or power plants of a similar specification
Features

Specifications
Suitable only for jet A1 and diesel. Aviation/military standard equipment
Case construction
The Portapump unit is a rugged, all-weather fuel pump
designed for the rapid fuelling or defuelling of all types of
aircraft or vehicles using jet A1 or diesel with a flash point
above 37°C.
It is designed to be easily transported by aircraft, helicopter or
vehicle. Able to be carried by a single person, it uses a powerful
24–28 volt DC motor direct coupled to a high-speed pump
with phosphor bronze sliding vanes.
The power source can be any 24/28 volt supply such
as a portable GPU, vehicle battery or aircraft DC bus.
Alternatively a 110/220 volt AC supply can be used with a DC
voltage converter.
Fuel drums or containers that would otherwise require a
settling period after transport to allow fuel/water separation
can be pumped immediately. Fuel drained from aircraft,
that would otherwise have been discarded, can safely be
re-used once passed though the Portapump.
An inlet non-return valve prevents drainback (siphoning) and
maintains the back pressure to allow activation of the pressureoperated switch that shuts off the pump motor.
Normal pumping is indicated by a reading of approximately 5
PSI on the gauge. Progressive filter blocking is indicated by a
gradual rise in differential pressure. At approximately 15 PSI the
coalescer filter cartridge should be removed and replaced if
necessary. A drain tap is fitted to allow any collected water to
be removed daily.

Installation • commissioning • maintenance
Powervamp’s service team operates from its impressive
premises at Barton-le-Clay in Bedfordshire, one of the
companies two major UK sites (the other being located in
Weston-super-Mare).
REPAIRS AND MAINTENANCE
Product support is the core capability of the servicing operation.
Skilled engineers can handle repairs and maintenance across the
entire range. Products can be returned to the service centre or
dealt with on site, as UK-wide travel is part of the company’s
service proposition.
An increasing number of Powervamp customers take out an
ongoing maintenance contract which can cover work on
competitors’ equipment, as well as Powervamp’s own product
lines. Activities range from routine battery checks and discharge
monitoring to complete swap-outs of faulty materials and
components.
To ensure that its service engineers have all the skills needed for
any eventuality, Powervamp runs a comprehensive induction and
training programme. New recruits are required to spend time on
Powervamp’s assembly line in order to gain knowledge of
product assembly. Staff are also trained extensively in servicing,
and repairing, prior to working in the field.
SITE SURVEYS
Powervamp also offers a detailed site surveying service which
includes assessing a site’s power requirements in order to
recommend an appropriate fixed electrical ground power unit.
Powervamp is regularly approached to calculate the costs when
companies wish to embark on an energy saving scheme,
providing more power-efficient equipment
COMMISSIONING
Commissioning is another key function for the servicing team.
Ground power unit operators such as major airports sometimes
arrange their own installation, but Powervamp engineers still play
a vital role, checking that the work has been done correctly –
verifying that electrical loads are within stated tolerance or that
the installation environment is appropriate. The process can also
include the safe disposal of life-expired components with full
compliance certification.
TURNKEY INSTALLATION
The team can also offer a complete turnkey installation and
commissioning package, either using its own staff or calling on
approved specialist contractors with experience and training in
Powervamp products.
