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.

PACKAGING

our UPS has been carefully packaged to
withstand most abuse sustained during

shipment. The packing material has been
specifically designed to protect this system for
normal handling, using most shipping carriers. If
there is significant damage to the carton, or if there is
any physical damage to this unit, report this to your
carrier.

These units are encapsulated in a protective wrap
that comes apart once the product is removed from
the shipping carton. Save all packing material for
future use.

The packaging also contains important information
on use and care as well as valuable warranty
information. Read all materials before storing this
literature with your other valuable product
documents.

PHYSICAL DESCRIPTION SP1250DLE

his section will point out and illustrate the
various indicators, functions and controls of

the SP1250DLE Series DC/AC Power Supply
with built in backup capabilities. The important
attributes of the SP1250DLE Series unit are
numbered to assist you in locating them on your
machine and also to fully explain its function and
how it relates to system operation.

Numbers on the drawing will correspond to the

operating component’s name at the bottom with a

brief identification. In the next section, a complete
explanation of all numbered items will be enhanced
to ensure you have a full understanding of the

visual indicators used on the front panel are long
lasting, very efficient, light emitting diodes (LED).
When operating the push-button switches, always
hold the switch in for at least two seconds to insure
function confirmation. This feature has been
implemented into the system design to avoid
inadvertent operation of any of the user-available
functions.
