Military-Grade 3-Phase Input UPS 1500VA

MIL-SPEC Uninterruptible Power Supply with Lithium Polymer Battery Backup

UPS-1500 Series Uninterruptible Power Supply units are designed for the extreme environmental and demanding electrical conditions of Military/Aerospace applications. SynQor’s UPS incorporates field proven high efficiency designs and rugged packaging technologies. This UPS will accept a wide range of input voltage and frequency values while delivering a well-conditioned AC output to the load. Up to three units can be combined to provide higher power, higher voltage and/or multiple output phases.

The use of lithium polymer batteries permits the lowest profile and lowest weight solution in its power class. Options include a 500W or single 1250W DC output, a DC input rated for military 28 VDC sources, and an electronic breaker on the AC output provides fault-tolerant parallel operation for higher power and/or N+M redundancy.

As the figure below shows, there is a nominal 28 V mid-bus within the UPS that draws power from one of up to three power sources: the 3-Phase AC INPUT (primary source), the optional DC INPUT (secondary source) or the battery (backup source). EMI filters are present at all external inputs and outputs.
