General Product Information
Product Description
The SynQor UPS-1250 DC Output Series is an advanced technology military-grade uninterruptible
power supply (UPS) that uses lithium polymer batteries and highly efficient power electronic
circuitry to achieve a high power level and battery run-time in a low-profile, low-weight, rack-
mountable package. It provides voltage conditioning, electrical isolation, and power flow
smoothing between the power inputs and its power outputs. It provides battery backed-up
power when other power sources are not present.
A communication/control port is available to permit monitoring and control by a host computer
system. Front panel LEDs and an audible alarm provide information on the status of the UPS and
the battery pack.
The UPS-1250 DC Output Series products can draw power from an AC input having a wide range
of voltage and frequency levels, or from an 28 V nominal DC input. The AC input has priority over
the DC input. The UPS provides up to 1250 W of DC output power at 28 volts nominal.
The electronic circuitry within the UPS-1250 DC Output Series products is designed, qualified
and screened according to SynQor’s MIL-COTS Standards. It complies with the requirements of
MIL-STD-704F, MIL-STD-1399-300B, MIL-STD-1275D and MIL-STD-461F, as well as IEC-EN61000
specifications for world-wide commercial utility applications.
The UPS-1250 DC Output Series products are designed and manufactured to withstand the harsh
environments and use encountered in military applications. The electronic circuitry and battery are
contained in a sealed chamber constructed from a die-cast aluminum chassis that is weather-proof
and shock-proof. Redundant, water-proof fans on the rear panel draw cooling air over the heat-sink
fins below the sealed chamber. Military-grade circular connectors are used, and optional attached
connector covers are available for when the cables are not attached. The UPS-1250 DC Output
Series products comply with a wide range of testing according to MIL-STD-810G.
The UPS-1250 DC Output Series has three product formats: 1) a 1U high unit that has a standard
battery pack that provides >10 minutes of full-power run-time, 2) a 2U high unit that has an
extended battery pack that provides >24 minutes of full-power run-time and 3) a 2U high,
shallow-rack unit that has a standard battery pack that provides >10 minutes of full power run
time. The first weighs approximately 33 lbs., the second 52 lbs. and the third 33 lbs.
The SynQor UPS-1250 DC Output Series products are designed and manufactured in the U.S.A.
