GENERAL FEATURES
The Power + SA Uninterruptible Power Supply (UPS) employs Pulse Width Modulation (PWM)
and is controlled by a micro-controller, to provide reliable, sophisticated protection against every
type of line fluctuation, including interruption of the mains (electrical) supply.
Figure 1: Block Diagram of the POWER+ UPS
In case of a power failure, the UPS provides backup power for a specific period.
The system is user friendly. Its operation is simple and requires no previous technical knowledge.
The UPS operates on-line and, once activated, provides voltages of 3×208 Vac at a stabilized 50
or 60 Hz frequency—depending upon your configuration—to load.
When backup service is provided (upon mains power failure), the UPS is powered by batteries
and maintains a constant output voltage supply. The system informs the operator, by means of
LED indicators and audible signals, when a power failure occurs.
An LCD display on the UPS front panel provides complete, real time information reflecting the
UPS’s operational status.
Using an RS232C communications port, similar status information may be viewed on a computer.

POWER+ SA User Guide (UL), Release 1.9
Gamatronic Electronic Industries Ltd.
2.1
Major Subsystems
The device consists of the following modules:
2.1.1
Charger
POWER + SA includes a 3-phase charger with PFC 1.
2.1.2
Batteries
The POWER + SA battery bank is used as a backup in the event that the utility ac input fails. The
batteries are housed in an external cabinet next to the POWER + SA cabinet. Batteries are
charged by the rectifier/charger, which supplies both the inverter and the battery charger.
2.1.3
Inverter
A 3-phase PWM inverter is connected to batteries by a classic dc link.
2.1.4
Static Switch (ST.SW. BYPASS)
The Static Switch enables an automatic transfer of the load from the output of the inverters to an
alternate source whenever the inverter can no longer supply power to the load. The static switch
transfers current at high speed.
1
PFC is a feature included that reduces the amount of generated reactive power. Reactive power operates
at right angles to true power and energizes the magnetic field. Reactive power has no real value for an
electronic device, but electric companies charge for both true and reactive power resulting in unnecessary
charges.
In power factor correction, the power factor (represented as "k") is the ratio of true power (kWatts) divided
by reactive power (kVA). The power factor value is between 0.0 and 1.00. If the power factor is above 0.8,
the device is using power efficiently. A standard power supply has a power factor of 0.70-0.75, and a power
supply with PFC has a power factor of 0.95-0.99.

Gamatronic Electronic Industries Ltd.
2.6
Log
The system compiles a listing of up to 200 extraordinary events of the mains, unit and load during
operation. This data is written to the log file and can be accessed easily at any time through the
display panel, computer, or via modem. This information is extremely useful for maintenance and
analyzing performance statistics.
2.7
Battery Check
The unit automatically and continuously checks the battery bank connection with the UPS. The
battery charge is checked automatically at user-controlled intervals, and a manual battery test
can be performed at any time.
2.8
Connections
The terminal connectors are located on the rear side of the UPS and may be accessed only after
removal of their protective cover with a screwdriver.
2.9
UPS Communications (optional)
The UPS relays all the measured data and events of the log file through an RS232C
communications port to a host computer or, using a modem connected to a telephone line, to a
remote location.

OPERATING MODES
The POWER + SA is installed between the power mains and your load devices, and supplies ac
electrical power to your equipment. The POWER+ SA has three automatic modes of operation:

Normal mode

Battery mode

Bypass mode
3.1
Normal Mode
POWER + SA almost always operates in normal mode. In normal mode the load receives its power
from the inverters that supply stabilized voltage, protected from spikes and irregularities in the ac
input. The ac input system feeds the charger which supplies dc power to the inverter, while
concurrently charging the batteries.
Figure 4: Normal Mode display
POWER+ SA User Guide (UL), Release 1.9
11
Gamatronic Electronic Industries Ltd.
3.2
Battery Mode
If the input ac power fails or the voltage drops below an acceptable level, the UPS operates in
backup mode. In backup mode the load continues to receive power from the inverters, but the dc
input to the inverter is taken from the batteries, instead of from the rectifier.
The batteries are galvanically connected by dc link to the inverter and the charger. The dc
inherently remains constant when the ac input supply drops out, without any switching devices.
The duration of the battery operation is determined by the load demand and battery capacity.
Figure 5: Battery Mode display
12
POWER+ SA User Guide (UL), Release 1.9
Gamatronic Electronic Industries Ltd.
3.3
Bypass Mode
In bypass mode the load receives power directly from the ac input via the static switch.
Whenever the inverters cannot provide power to the load, for example, due to an overload or a
short-circuit in the load, the UPS supplies the load directly from the ac input, bypassing the
inverter. As soon as the problem is corrected, the load is transferred back to the inverter
automatically.

12. MISCELLANEOUS FUNCTIONS
This section describes infrequently used but important features.
Manually entering or leaving bypass mode
When the ac input power is normal, it is handled by the UPS in one of two ways:

The input ac power is sent to the inverter, where it is regulated and passed on to the
load. This is called normal mode or inverter mode.

The input ac power bypasses the inverter entirely and goes directly to the load with no
regulation. This is called Bypass Mode.
Usually only a technician will need to manually switch the UPS to Bypass mode.
To manually enter or leave bypass mode:
1.
From the Main Screen, press the Ent button to display the Main Menu.
2.
On the MAIN MENU, select ADVANCED MENU and press Ent.
3.
On the ADVANCED MENU, select TRANSFER LOAD and press Ent.
The TRANSFER LOAD screen tells you if the load is currently on the INVERTER or if the
UPS is in BYPASS MODE.

14. TROUBLESHOOTING
This section explains what to do in the event of an alarm condition, or when any other “out of the
ordinary” event occurs on the UPS.
Alarm sounds and/or alarm LED lights up
1.
Go to the Event Log and look at the Active Alarm Display to determine the nature of the
alarm. See “Navigating to the Event Log” and “Active Alarm Display” on page 35.
2.
Look for the appropriate heading below according to the nature of the alarm, and follow the
instructions.
Electricity returned but UPS remains in battery mode
Check the external circuit breaker for the ac line. The circuit breaker may be off.
Battery test failed
It may be that an automatically scheduled battery test was executed shortly after the end of a
power outage, when the battery was still charging. Wait until about two hours after the return of

Input and output wiring for two-phase operation
As shown in Table 2 on page 63, there are two options for two-phase operation:

Where the two input phases to the UPS have a phase shift of 120°. In this case, the
effective input and output voltage between the phases is 208 Vac.

Where the two input phases to the UPS have a phase shift of 180°. In this case, the
effective input and output voltage between the phases is 240 Vac.
Input and output wiring for two-phase operation
For both two-phase options, the wiring is the same (refer to Figure 19):
For input: One input phase is connected to UPS input L1, the second phase is connected to
UPS input L2. UPS input L3 is not used. Neutral input is connected to the neutral connector of the
ac input terminal, and ground is connected to the ground connector of the ac input terminal.
For output: UPS output L3 is linked to UPS output L1. The load takes one output phase from L1,
the second output phase from L2. Neutral output comes from the neutral connector of the ac
output terminal. Ground for the load comes from the ground connector of the ac output terminal.
