2GENERAL DESCRIPTION
Introduction
You have just purchased an Uninterrupted Power Supply (UPS) System.
In order to get highest efficiency from your product and to ensure a safe use, we recommend that you strictly read
and retain this operating manual for later reference. In addition, do not hesitate to contact customer service for
more detailed information and/or assistance (s[email protected]).
The UPS will be connected between the load and the grid. The purpose of this device is to provide the load with
controlled power for each load and input supply condition. The power provided by the UPS will be protected from
all variations in grid´s voltage and frequency by supplying electrical power to the load in a stable, controlled and
disturbance-free manner.
ZGR TOWER PRO 1-3 KVA
connected to the single phase network, and supply an output voltage which is also single phase. These consist of
an electronic high frequency rectifier with active power factor corrector, which supplies a inverter stage, a battery
charging circuit and an output filter that provides quality, disturbance/harmonic-free output.
In case of a mains failure, the load supply is guaranteed by the battery power supply for a backup time that varies
depending on the capacity of batteries used. If mains voltage is recovered during the backup time, UPS will return
to normal mode automatically and continue supplying power to loads. Meanwhile, batteries are charged as well.
In the case of an overload or breakdown of one of the UPS stages, the UPS has a bypass that guarantees the
power supply to the load uninterruptedly. Once overload is recovered or the breakdown is repaired, load is
transferred back to normal mode.
A microprocessor is responsible for controlling the different circuits and for presenting the UPS status through a
liquid crystal display (LCD) and LED indicators.
The UPS can be monitored remotely via a computer by using several communication protocols.
System used in ZGR TOWER PRO 1-3 KVA uninterruptible power supply is shown in the following simple block

Main characteristics
•Low distortion sinusoidal output voltage: a modern inverter with modulation control of the pulse width
(PWM) generates a sinusoidal output with minimum distortion, allowing power to be supplied to sensitive
apparatus.
•High input power factor and low distortion sinusoidal of input current: the high frequency rectifier
or corrector (PFC) which allows the UPS consumes power with a power
factor near to unity and with a low distortion sinusoidal of input current, no matter what type of connected
load to the equipment.
•Microprocessor control: All the power conversions are controlled by totally digital signal. Excellent
performance and reliability are realized together with all kinds of protection functions.
•Instantaneous transition from normal to battery mode operation and vice versa: as this is a double
conversion model, there is no failure in the output voltage in transitions between mains and battery.
•High input voltage range: The rectifier works at mains of low voltages at full load, which prevents energy
from being extracted from the battery even at these voltages.
•High efficiency: this UPS range has a high efficiency up to 92%.
