I. GENERAL DESCRIPTION
1.3 Introduction
INFORM PDSP Series Uninterruptible Power Supplies are double-conversion, on-line UPS’s, manufactured
with the latest IGBT and PWM technology, to produce an uninterruptible, microprocessor controlled pure sine
wave output to critical loads.
INFORM PDSP Series units are 3-phase in/3-phase out devices, and they are installed between a three phase
critical load, and a 3-phase+N mains supply
The advantages of using PDSP UPS:
• Power blackout protection:
If the mains power fails, the UPS continues to supply the critical load using the energy stored in its
batteries, keeping the load immune from power disturbances.
• Increased power quality:
The UPS has its own internal voltage and frequency regulating circuits, which ensure that, its output to the
critical load 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 (Double-Conversion) any
electrical noise present on the input mains supply line is effectively isolated from the UPS output. Therefore
the critical load is supplied with only clean and uninterrupted AC power.
