The internal energy source (the battery) cannot be de-energized by the user.
When changing batteries, install the same number and same type of batteries.
I. GENERAL DESCRIPTION
1.1
Introduction
VISION DSP0.9 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.
VISION DSP0.9 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 DSP0.9 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.
