Operation; General Description; System Configuration; Ups Control - Powercom Line-Interactive 1025AP User Manual

Necessary information for the operation of the unit is covered in this chapter.
Normally UPS runs automatically, but on a few occasions such as just after
installation, all procedures are described herein.

4.1 General Description

As Line-Interactive UPS, it is capable of providing clean and stable power to your critical
system. While the UPS regulates and filters power fluctuation, it also keeps the battery
charged for any emergency.
 Automatic transformer regulates over and under-voltage power.
 During a power failure, the UPS immediately provides backup power from the
battery to support your essential equipment.
 Power transference is typically achieved uninterrupted within 4 milliseconds
Line-Mode/Battery-Mode
UPS will operate in Line-Mode that supports power and charge battery while
connected to power. During a power failure, the UPS will switch to Battery-Mode, in
which power is maintained from the battery. In case of failure time exceed
Battery-Mode duration, UPS will shut down until voltage return to prevent battery
discharge.
Diagnostic Test
While the advanced battery management system monitors the conditions of the
batteries, it sends early warnings if a battery replacement is needed. Diagnostic tests
can be performed from the control panel.

4.2 System Configuration

The UPS device and battery make up the system. Depending on site and load
requirements, certain additional options are available as tailored solutions. Please
consider the following when planning your UPS system:
 The total demand for the protected system shall dictate the output power
rating (VA). When measuring demand, please allow a margin for future
expansion and calculation error.
 Battery-mode duration needs dictate the battery size. If the load is less than
the UPS nominal power rating, then the actual backup time is longer.
