INVERTRONIC compact
Cost Saving Power Protection Availability
Mains failure and mains disturbances
may cause serious problems
Invertronic compact inverter systems ensure
continuous power protection availability
More and more mission critical loads for industrial and commercial applications require a smooth and uninterrupted supply of electricity.
Benning`s new advanced INVERTRONIC compact single phase
inverter systems provide continuous and high quality AC power
for mission critical loads in the industrial and commercial
market place.
On the public network, major loads as well as lightning strikes,
generate dynamic over voltages, under voltages,
sags/brownouts and transients.

The INVERTRONIC compact inverter modules offer a very
flexible platform to design compact AC/AC power solutions in
combination with the modular rectifier range 3000I and
12000I.

Malfunctions in the public network (see table of mains disturbances above) may cause hardware failure, disruption of critical loads, unplanned production downtime or loss of
communication.
The INVERTRONIC compact range consists of the
following system components:
Inverter systems are often the perfect choice to supply reliable
and conditioned AC power to mission critical applications.
1. 19”sub-rack
The 19” sub-rack is designed to accommodate the
INVERTRONIC modules and can be integrated into 19” floor
standing or wall mounted cabinets.
The following sub-rack versions are available:
1. Sub-rack with back plane connections for up to 3 inverter
modules, one static bypass module and a manual
bypass. (fig. 1)
2. Sub-rack with back plane connections for up to 5 inverter
modules. (fig. 2)

2. Parallel operating Inverter modules
INVERTRONIC inverter modules are available for use with
DC input voltages of 110V or 220V. The standard AC output
voltage is 230V, but 220V and 240V are selectable. Each
inverter module can supply 1.5kVA rated output power.
The hot-plug design of the inverter modules together with
the dimensions of 1/5 19 inch width and 3U height allows
the accommodation into 19 inch 3U sub-racks.
3. Static bypass switch
The static bypass switch increases the availability of the
inverter system and provides security during overload or
short circuit.
The bypass switch transfers the load to the mains if the
inverter output deviates outside the acceptable tolerances
for both, voltage and frequency, caused by short circuit,
overload, or inverter failure.
Automatic transfer of the load back to the inverter is made
after the inverter output has returned to within tolerance.
The transfer time is less than 2ms.
The static bypass has the same dimensions as the
inverter modules and can be integrated into the 19 inch
sub-rack. (Fig.5).
4. Manual bypass switch
The additional integrated manual bypass switch is located
beside the static bypass switch and allows the manual
transfer of the load to the mains or to the inverter output.
This switch allows the inverter modules and the static
bypass module to be bypassed for service reasons.

Monitoring system MCU 2500
Figs 7 & 8, show different sizes of cabinets with sub-racks for
inverters only and a combination of inverters and rectifiers.
The Monitoring system MCU 2500 allows local or remote operation of the INVERTRONIC compact systems.
The integration of battery and load fuses/breakers is also
possible.
The display and operation unit mounted on the front door of
the system cabinet consists of liquid crystal display, 17 LED`s
and 4 push buttons and allows local operation of the power
system.
Remote control and monitoring is possible using modem,
Ethernet, Web, SNMP, MODbus or Profibus. (Fig10)
