A new range of ruggedized, flexible high power AC/DC PSUs has been released by
Powerstax. The company advises its MC1U series are available in 400W (MC1U-6A), 700W (MC1U-6B) and 1000W (MC1U-6C) versions, supporting a 47Hz to 440Hz input frequency range. Design features include an output voltage adjustble as required using an integrated multi-turn potentiometer. They measure 26.0cm by 12.7cm by 4.0cm, are user-configured PSUs, exhibiting power conversion efficiencies 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 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 this 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 3000VAC 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.
