Rugged, high-power PSUs for military COTS and other demanding applications

Powerstax' new MC1U series of power supply units (PSUs) is offered in 400W (MC1U-6A), 700W (MC1U-6B) and 1,000W (MC1U-6C) versions.

Supporting a 47Hz to 440Hz input frequency range, these PSUs can easily be adapted to meet exact functional specifications - with the output voltage adjusted as required using an integrated multi-turn potentiometer.

Measuring 26.0cm x 12.7cm x 4.0cm, these user-configured PSUs have a power conversion efficiency of up to 91 percent. The available input voltage range is 85Vac to 264Vac at 47Hz to 63Hz and 90Vac to 120Vac at 390Hz to 440Hz. These units can be combined with the company’s A3600 chassis for 19in rack mount configurations.

UL60950, CSA22.2 No.950 and EN60950 approved, as well as fully conforming to both MIL-STD-461F (for electromagnetic interference) and MIL-STD-810G (for shock and vibration) standards, the products in the MC1U series are targeted at implementation in military commercial-off-the-shelf (COTS) and other high-reliability systems.

Over-current, over-voltage and in-rush current protection mechanisms are incorporated into these units, as well as thermal shutdown. They also have a 3,000Vac voltage isolation and an operational temperature range spanning from -55ºC to 70ºC. A conformal coating on their exterior offers added protection against dust and liquid ingress.
