1. Introduction
1.1 Overview
PC-Power is an advanced line-interactive Uninterruptible Power System (UPS), designed to protect sensitive
equipment, such items as computers, telecommunication systems, and computerized instruments, from
spikes, surges, saps, transients and blackouts.
When mains is present, the UPS filters small fluctuations continuously. When mains fails, the UPS uses its
internal battery to supply back-up power.
1.2 Smart Buck and Boost Line Conditioning
The standard European nominal mains voltage is 230V. The actual mains voltage can fluctuate above or
below this nominal value. To protect sensitive loads from such mains fluctuations, the UPS provides line
conditioning using both buck (step-down voltage) and boost (step-up voltage) functions.
The line conditioning feature allows the UPS to provide protection over a wider mains voltage range
without drawing power from its internal battery.
1.3 User Replaceable Battery Design
The internal battery is the most critical component in the UPS. It has a design life of between 3-5 years.
With a PC-Power UPS, the battery can be replaced by the user, even in hot mode.
1.4 Advanced Computer Interface
PC-Power UPS provide complete RS232 and volt-free contact interfacing.
Using the UPS monitoring and shutdown package, OptiSafe, a user can use a computer screen to determine
the input/output voltage and current, frequency and battery voltage, etc, and analyse power problems.
1.5 User Configurable Settings
The operating parameters of a PC-Power UPS can be adjusted to suit the characteristics of its site.
