Behlman Announces That Their New VPXtra(TM) 1500CS AC-to-DC Front End Power Supply Breaks through another Power Ceiling

This may be the VPX industry’s highest-power 6U front-end power module.

Hauppauge, New York, — Behlman Electronics Inc., known for its break-though leadership in VPXtra™Â  power products for military, industrial, and commercial applications, has introduced the VPXtra™1500CS Three-phase AC-to-DC COTS power supply.

In late 2012, Behlman raised the VPX power bar to an unprecedented 1000 Watts with two 6U Open VPX VITA 62 Compliant DC-to-DC COTS power supplies: VPXtra™ 1000CD (Dual-output) and VPXtra™1000CM (Multi-output).

Now, with the introduction of the new Behlman VPXtra™ 1500CS, VPX design engineers can obtain a DC output from a three-phase AC source, to support design initiatives requiring power factor correction and input current harmonic reduction. Although initially conceived to power Behlman’s VPXtra™1000CD and VPXtra™1000CM DC-to-DC power supplies, VPXtra™ 1500CS can also be used to power devices from other manufacturers having similar wide-range DC inputs.

VPXtra™ 1500CS is a rugged, highly reliable, conduction-cooled, switch mode unit built for high-end industrial and military applications. It accepts 115/200 VAC, 3-phase input, IAW MIL-STD-704, and delivers 1500 Watts of 33 VDC power. Input current complies with CE101 and MIL-STD-1399. This front-end module is designed and manufactured using Behlman’s outstanding Xtra-Cooling™, Xtra-Rugged™ Construction and Xtra-High™ Reliability. It has no minimum load requirement and has short circuit protection, as well as over-voltage and thermal protection.

According to Behlman President, Ron Storm, “When we introduced the VPXtra™ 1000CD and VPXtra™ 1000CM power supplies, we knew that the VPX industry would benefit greatly from having a reliable front-end module that would deliver DC power from 115/200 VAC, 3-phase inputs. It took Behlman a year to perfect the solution in the form of the VPXtra™ 1500CS, but the additional capability and versatility provided by this unit will prove to be well worth the effort.”

VPXtra™ 1500CS features include:

• Open VPX VITA 62 compliant

• 6U VPX, 1.0” pitch single slot

• Three-phase AC input, 47-440 Hz

• High-power DC output: 33 V/46 A
