PowerPro HP300 Series User Manual
I. GENERAL DESCRIPTION
1.1 Introduction
T-300P Uninterruptible Power Supplies, are On-Line UPS’s, being manufactured with the state-of-the art
PWM and IGBT technology, produce micr oprocessor controlled pure sine wave output to critical loads.
T-300P series UPS’s install between the critical load and the mains.
The advantages of using UPS:
•
Power blackout protection:
If the mains power fails, the UPS continues to power the critical load from its battery source, leaving the
load immune from power disturbances.
•
Increased power quality:
The UPS has its own internal voltage and frequency regulator circuits, which ensure that its output is
maintained within close tolerances independent of voltage and frequency variations on the mains power
lines.
•
Increased noise rejection:
By rectifying the input AC power to DC power, and then converting it back to AC, any electrical noise
present on the input mains supply line is effectively isolated from the UPS output, therefore the critical load
sees only clean power.
