2. 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 2-1: 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.

Gamatronic Electronic Industries Ltd. User Guide
POWER+SA User Guide (UL), Release 1.8 7
2.1 Major Subsystems
The device consists of the following modules:
2.1.1 Charger
POWER +SA includes a 3-phase charger with PFC1.
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.
1PFC 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.

User Guide Gamatronic Electronic Industries Ltd.
8 POWER+SA User Guide (UL), Release 1.8
2.1.5 Control System
The control system performs the following functions:
•Tests input, bypass, inverter, battery voltage, output current, input/output
signal frequency, and temperature.
•Manages the static switch and charger voltage during battery tests.
•Controls the ALARM interface.
•Controls the panel keyboard reading and sends messages to the front panel
LCD display.
•Communicates with devices via the RS232C interface.
2.2 Control Panel
The UPS is equipped with an LCD display and touch pad control panel that enable the
user to effectively manage the UPS. Once the UPS is installed, the control panel
serves as the user’s primary interface with the system. Messages, warnings and error
conditions are relayed to the user through the control panel’s LCD display and
through audible alarms.
Figure 2-2: Control Panel

Gamatronic Electronic Industries Ltd. User Guide
POWER+SA User Guide (UL), Release 1.8 9
2.3 Power-On Self Tests

condition simply by pressing the appropriate status button. The real-time results are
displayed on the front panel, as shown in Figure 2-3.
Figure 2-3: The LCD screen displays real-time readings
2.5 Real Time
The system includes a real-time clock and calendar that sequentially manage the log
file and provide historical data to the user. This information is accessible via the LCD
display or, optionally, through the RS232 communications port.

User Guide Gamatronic Electronic Industries Ltd.
10 POWER+SA User Guide (UL), Release 1.8
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.

POWER+SA User Guide (UL), Release 1.8 11
3. 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 3-1: Normal Mode display

User Guide Gamatronic Electronic Industries Ltd.
12 POWER+SA User Guide (UL), Release 1.8
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 3-2: Battery Mode display

Gamatronic Electronic Industries Ltd. User Guide
POWER+SA User Guide (UL), Release 1.8 13
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.
