TECHNICAL DESCRIPTION
he Digital Technology-Extreme Temperature
SP560/SP1250LE Series Continuous Power
System (CPS) is a revolutionary new concept in total
power protection and management. The
SP560/SP1250LE Series is a DSP processor-based
UPS that allows the user to set most of the control
feature parameters. By directly linking a personal
computer to the SP560/SP1250LE Series Com
ports, frequency settings and operation, alarm
signals, load switching, fan operation, etc. can all be
programmed to meet specific application
requirements.
The SP560/SP1250LE Series is a true on-line,
continuous power UPS. In the tradition of Clary
products, the SP560/SP1250LE Series generates
the same high quality and proven reliability to provide
the best power protection available for today’s critical
applications.
In keeping with the state-of-the-art design, the power
electronics are completely governed by an on-board
DSP based processor. Given the powerful
processing capability of today’s DSP chips, this
allows the UPS to evolve into an all-in-one complete
power distribution and monitoring center. Not only is
your critical load insured of the most reliable and
constant power available, but the user may now
continuously monitor the status of the various
operational parameters in the system.
The AC utility source is connected to the power
switching and control electronics when the input
switch is closed. The input line is filtered, rectified
and power factor corrected for enhanced
performance without disturbing other equipment that
may share the same utility circuit.
The DSP processor controls an Inverter Generator
that produces a clean, low harmonic, AC output
sinewave for continuous power applications.
When the input AC utility line fails, the battery circuit
within this system takes over to ensure continuous
power. Only when properly rated input power is
returned, does the unit reconnect the input source
back to the system.
The unit is connected to a Com port which allows the
user to monitor and set operating parameters. With
a simple link to a personal computer using the
“SP560/SP1250LE UPS software program”, the user
can view the event history of the power distribution
system. More sophisticated users may choose to
implement the optional SNMP package to allow full
Network Power Management capability.
