Introduction
Thank you for choosing our high technology C1 Series™ uninterruptible power
supply. Product you purchased was manufactured as per ISO9001 quality assurance
system using most advanced technology.
In order to get highest efficiency from your product and to ensure a safe use, we

1. Overview
C1 Series Uninterruptible Power Supply (UPS) is a high technology product
that was manufactured to provide uninterruptible energy to fields including but not
limited to industrial facilities, hospital, schools, banks, business centers, and
computer and communication systems. You can use your device, which is equipped
with static bypass system, all necessary protection systems and an online structure
with all loads safely.
Because this device was designed double conversion online system basis, it
supplies all connected loads with continuous voltage with stable frequency and stable
amplitude. Therefore, no transition period is necessary when electric power is
interrupted or recovered.
With deployment of a DSP (Digital Signal Processor) based microprocessor
in its design, UPS output voltage is accurately controlled, thereby ensuring stable
operation of devices that are sensitive to voltage fluctuations.
Static bypass unit of the system ensures that the mains voltage is constantly
kept at backup. In case of an overload, this system takes over the load
uninterruptedly. Once overload is recovered, load is transferred back to inverter. In
addition, static bypass unit acts in similar way in cases of UPS failure and prevents
power shortage at the system.
UPS will supply loads from the battery in cases of mains voltage outage.
Loads are supplied from the battery 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 online mode automatically and continue supplying power to loads.
Meanwhile, batteries are charged as well.
When UPS is connected to a computer system using any of a several
communication options, all functions of the device can be monitored by means of
designated software. Connecting to a remote device via modern is possible to
transfer information on device related functions and problems.
System used in C1 series uninterruptible power supply is shown in the
following simple block diagram.
