I. GENERAL DESCRIPTION
1.1
Introduction
TESCOM DS300SHP Series Uninterruptible Power Supplies are double-conversion;
on-line UPS’s manufactured with the latest IGBT and PWM technology, to produce an
uninterruptible,
fully DSP (Digital Signal Processor) controlled
pure sine wave output to
critical loads.
TESCOM DS300SHP 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 DS300SHP 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 software, which
ensures that, its output to the critical load is maintained within close tolerances, independent
of voltage and frequency variations on the mains power lines.
•
Fully digital control by three DSP controller for each UPS:
The UPS is controlled by 3 independent DSP chips which are communicating each
other continuously. Rectifier, Inverter and User Interface modules have separate DSP’s to
achieve the highest performance. Each DSP module has many parameters to control and
monitor the system to have the best electrical power output and to help diagnostic.
•
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.
