AC-DC MIL-COTS Power Supply

The MC1U series from Powerstax plc comes in 400 W (MC1U-6A), 700 W (MC1U-6B) and 1000 W (MC1U-6C) versions, supporting a 47 Hz to 440 Hz input frequency range, these power supply units (PSUs) provide design engineers with a plug and play solution that can easily be adapted to meet their exact functional specifications - with the output voltage adjusted as required using an integrated multi-turn potentiometer. Measuring 26.0 cm x 12.7 cm x 4.0 cm, these user-configured PSUs exhibit power conversion efficiencies of up to 91%. The available input voltage range is 85 VAC to 264 VAC at 47 Hz to 63 Hz and 90 VAC to 120 VAC at 390 Hz to 440 Hz. These units can be combined with the company's popular A3600 chassis in order to form 19" rack mount solutions.

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 into military commercial-off-the-shelf (MIL-COTS) and other high reliability (high-rel) systems, such as marine/military communication, satellite guidance, avionics and radar. Over-current, over-voltage and inrush current protection mechanisms are incorporated into these units, as well as thermal shutdown. They also have a 3000 VAC voltage isolation and an operational temperature range spanning from -55 ºC to 70 ºC. A conformal coating on their exterior offers added protection against dust and liquid ingress.
