Behlman Electronics Inc., known for its leadership in power products for military, industrial, and commercial applications, has been providing its RUPS-1250 Uninterruptible Power Source (UPS) to support many critical applications not possible with standard UPS units. Examples range from rack-mounted RUPS-1250 units installed on aircraft to supply battery-backed ground power; to installation in ground-based equipment cabinets; and suitcase configurations that can be quickly deployed for portable operation anywhere in the world.
Says Behlman President Ron Storm, “I am proud to announce a new lower price, making RUPS-1250 an even better choice for high-end industrial and airborne, mobile, ground and shipboard applications that need the flexibility and versatility that only this unit provides.”
Behlman’s RUPS-1250 units can operate from an aircraft’s variable frequency (350-450 Hz) and output regulated 115 Vac at 50 Hz, 60 Hz or 400 Hz. They can also operate from either a 50 Hz or 60 Hz ac main or generator, and output 50 Hz, 60 Hz or 400 Hz. This selectable frequency capability, combined with its 95 to 270 Vac power-factor-corrected input capability, makes the Behlman RUPS-1250 UPS a candidate for uninterruptible power protection of mission-critical systems.
The U.S. Air Force has tested the Behlman RUPS-1250, and approved it for use on Air Force large-body fixed-wing aircraft.
Other exceptional features of the Behlman RUPS-1250 include 1,250 VA/1 kW output; PFC input; hot-swappable batteries (from the front panel) that provide five minutes standard, and up to twelve minutes run time at full load; alarms with contact closure; RS-232 interface for remote monitoring and control; cold start using DC in the event of an ac power failure; slides; and the ability to connect to a customer-supplied 28 Vdc to turn the output on/off.
RUPS-1250 input is power factor corrected with Galvanic Isolation; output is a sine wave with frequency conversion capability; and it can supply 115 Vac at a fixed voltage or temperature.
