High Performance Conduction Cooled COTS Power Sources

Powerstax has just added two new switch-mode COTS DC-DC power supply units to its portfolio which are designed to cope with even the most demanding application environments. The Behlman VPXtra 1000CM is a rugged, highly reliable, OpenVPX and Vita 62 compliant unit that accepts a wide range 28 Vdc input. It is 600 W DC rated across 5 outputs. These outputs offer 12 Vdc at 40 A, 5 Vdc at 24 A, 3.3 Vdc  at 15 A, -12 Vdc at 2 A and +12 Vdc at 1 A, with the unit's 12 Vdc output capable of being paralleled in order to attain higher power or for the purpose of including redundancy. The advanced Xtra-Cooling technology dissipates heat from the unit and maximizes operational longevity. The VPXtra 1000CM has no minimum load requirement and boasts extremely effective over-voltage, over-current, short circuit and thermal protection features. Its input-to-output isolation covers up to 500 Vdc, while its line and load regulation are 0.5% and 1.0% respectively.

To complement this, Powerstax now also markets the VPXtra 1000CD - a dual output COTS dc-to-dc unit that has the same wide range 28 Vdc input as the VPXtra 1000CM along with an identical card edge conduction cooling mechanism, but delivers up to 1000 W of clean, regulated 12 Vdc output power and 3.3 Vdc auxiliary power. Both these units are targeted at deployment in mission-critical airborne, shipboard, vehicle and mobile VPX power applications, as well as high-end industrial hardware. They are IAW MIL-STD-704 compliant.
