Behlman UPS Delivers Uninterruptible Power, With Frequency Conversion Capability, From Any Ground, Sea, Air or Worldwide AC Source

Behlman Electronics Inc., a specialist in power products for military, industrial, and commercial applications, has provided its RUPS-1250 Uninterruptible Power Source (UPS) for use in many 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.

Behlman’s RUPS-1250 units can operate from an aircraft’s variable frequency (350-450 Hz) and output regulated 115Vac at 50 Hz, 60 Hz or 400 Hz. They can also operate from either a 50 Hz or 60 Hz main and output 50 Hz, 60 Hz or 400 Hz. This selectable frequency capability, combined with its 95 to 270Vac Power Factor Corrected input capability, makes the Behlman RUPS-1250 UPS a truly unique, go-anywhere solution for uninterruptible power protection of mission-critical systems.

The U.S Air Force has tested the Behlman RUPS-1250 for compliance to MIL-STD-461F EMI and approved it for use on Air Force large-body fixed-wing aircraft.

Other features of the Behlman RUPS-1250 include 1250VA/1000W output, PFC input, hot-swappable batteries (from the front panel) that provides 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 28Vdc 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 a fixed 115Vac at a fixed frequency of either 50 Hz, 60 Hz or 400 Hz, ±0.1 percent regardless of load, input voltage or temperature.

Recent applications of the Behlman RUPS-1250 include installation aboard aircraft used to transport VIPs who require fail-safe communication systems; installation on USAF aircraft to supply battery-backed ground power for critical equipment; deployment to desert field posts in Iraq and Afghanistan; and operation at major aircraft manufacturing, repair and maintenance facilities.

According to Behlman Vice President of Sales and Marketing Ron Storm, "The extremely varied use of RUPS-1250 is especially gratifying, because it validates the expertise of the Behlman engineers that have taken UPS design to a whole new level. Now, more than ever, high-end industrial and military requirements, including aerospace, mobile, ground and shipboard applications, need the flexibility and versatility that only this unit provides."

RUPS-1250 UPS systems are available from $8,795 depending on configuration and quantity. Delivery is approximately six weeks.
