CONVENTIONS USED IN THIS BOOK
The POWER+ SA UPS is capable of operating with any of three possible line
configurations:
•3-phase input – 3-phase output (abbreviated “3-3” )
•3-phase input – 1-phase output (abbreviated “3-1”)
•1-phase input – 1-phase output (abbreviated “1-1”).
The configuration used by the UPS depends on the AC input supplied and on the
UPS settings.
It follows that the UPS informational screens that display input and output voltages
and/or current will show data for one or three phases depending on the unit’s current
operating parameters. The figures below show the UPS Main screen displaying
output voltages in 3-phase and in 1-phase operation, respectively.
UPS Main screen with 3-phase output
UPS Main screen with 1-phase output
In this user manual, when illustrating a given UPS function that includes a voltage
display, both possible displays are usually not shown (the single-phase display and
the 3-phase display).
For simplicity’s sake, usually only one of the two possible displays is shown. The
reader is asked to remember that the number of phases displayed on the screeen of
his UPS depends on the UPS settings and the actual AC input.

1. INTRODUCTION
Thank you for purchasing a POWER+ SA UPS system.POWER+ SA is one of the
most sophisticated UPSs on the market today.
In general, an Uninterruptible Power Supply (UPS) provides backup power for use
when the utility AC electric power mains fail or drop to an unacceptable voltage
level. POWER+ SA answers this critical need, and more.
POWER+ SA is designed to protect your data and equipment and minimize
downtime and other adverse effects normally incurred by power irregularities and
failures.
POWER+ SA continually eliminates surges, spikes and sags that are inherent in
commercial utility power. Over time, these irregularities shorten the life of equipment
and components. The efficiency of POWER+SA thus helps to extend the life of your
equipment, even during normal use when the input power is constant and
continuous.
POWER+ SA is unique because it
•Is a true on-line battery design according to IEC 62040-31.
•Is a "green" power solution thanks to THD of 5% at the input, and provides
“clean” power to your loads.
•Has an overall efficiency of up to 96% and backup efficiency of 98%.
•Is relatively light and small.
•Can operate in any of three line configurations: 3-3, 3-1, or 1-1 (see page 33).
POWER+ SA requires little attention or intervention during normal operation;
however, you should read and understand the procedures described in this manual
to ensure trouble-free operation.
1IEC 62040-3 is a standard for UPSs, authored by the International Electrotechnical Commission (IEC).
The IEC is the leading global organization that prepares and publishes international standards for all
electrical, electronic and related technologies. These serve as a basis for national standardization and
as references when drafting international tenders and contracts.

Major Parts of the POWER+ SA
The POWER+SA includes the following sub-assemblies:
The POWER+ SA
CONTROL PANEL
The POWER+SA control panel allows the user to:
•manage and control the POWER+SA
•monitor the parameters of all sections of the POWER+SA
CHARGER
The UPS includes a 3-phase charger with PFC2.
2PFC 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 (kvar). 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.

POWER+SA User Guide, Release 1.6 3
INVERTER
A 3-phase PWM inverter is connected to batteries by a classic DC link.
STATIC SWITCH (ST/SW)
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.
BATTERY
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, which supplies both the inverter and
the battery charger.

2. 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
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.
Normal Mode display

Gamatronic Electronic Industries Ltd.
POWER+SA User Guide, Release 1.6 5
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.
Battery Mode display
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.

The POWER+ Display Screen
The display screen on the POWER+ SA control panel shows the current operating
mode and related critical data. There are several distinct data screens that can be
shown on the POWER+ SA display screen.
The Main Screen
The POWER+ SA Main Screen is the default display on the POWER+ SA screen.
From any other screen, if the keyboard is not used for 45 seconds, the POWER+ SA
returns to the Main Screen.
The Main Screen shows the UPS’s current operating mode and other critical data.
Other screens describing current operating conditions can be seen by navigating
“upwards” or “downward” with the UP/DOWN key.
The first line of the Main Screen shows whether the UPS is currently on or off. The
second line tells you the most important information about the UPS’s current status.
Most of the time it will read “NORMAL MODE”. The UPS can also automatically
transfer to:
•BATTERY MODE
•BYPASS MODE
•UPS OFF
The L1, L2, and L3 numbers in the Main Screen show the current load rate as a
percent of maximal AC load at each phase.
