Conduction cooled power units maximise operational longevity
Two switch-mode COTS DC/DC power supply units have been added to Powerstax's power supply portfolio. Designed to cope with demanding application environments, the Behlman VPXtraä 1000CM is a rugged, OpenVPX and Vita 62 compliant unit that accepts a wide range 28VDC input.
It is 600W DC rated across 5 outputs. These outputs offer 12VDC at 40A, 5VDC at 24A, 3.3VDC at 15A, -12VDC at 2A and +12VDC at 1A, with the unit’s 12VDC output capable of being paralleled in order to attain higher power or for the purpose of including redundancy. The advanced Xtra-Coolingä technology dissipates heat from the unit and maximises operational longevity. The VPXtraä 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 to500VDC, while its line and load regulation are 0.5% and 1.0% respectively.
To complement this, Powerstax now also markets the VPXtraä 1000CD - a dual output COTS DC-DC unit that has the same wide range 28VDC input as the VPXtraä 1000CM along with an identical card edge conduction cooling mechanism, but delivers up to 1000W of clean, regulated 12VDC output power and 3.3VDC 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.
