AC-to-DC Front End Power Supply

Behlman Electronics Inc. has introduced the VPXtra(tm)1500CS Three-phase AC-to-DC COTS power supply. Now, with the introduction of the new Behlman VPXtra(tm)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.
