TECHNICAL DESCRIPTION
he DC/AC Digital Technology-Extreme
Temperature SP1250DLE Series
Continuous
Power System (CPS) is a revolutionary new concept
in DC/AC total power protection and management.
The SP1250DLE 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 SP1250DLE Series Com ports,
frequency settings and operation, alarm signals, load
switching, fan operation, etc. can all be programmed
to meet specific application requirements.
The SP1250DLE Series is a true on-line, DC/AC
continuous power source. This product is a design
result of the need for the new, next generation of DC
Powered Traffic Control Cabinets. In the tradition of
Clary products, the SP1250DLE Series generates
the same high quality and proven reliability to provide
the best DC/AC 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 DC/AC 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, while
the DC output stages provide continuous low ripple
power.
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
.
