DC-DC conduction cooled from 50W to several kWs

The PST21A, a very compact and low profile AC-DC power supply up to 1200W in chassis format, incorporates input filtering, input and output protections, very robust mechanical mounting and connection, conformal coating, and MIL-STD options required in most of the severe environments for industrial, defense applications. The PSU provides high reliability thanks to the integration of Vicor Corp. modules, high efficiency, input-to-output isolation, soft start and active very low inrush circuit, overtemperature protection, and input over/under voltage lockout.

The PSU is configurable with 1 to 6 outputs in many output voltages from 2V to 54Vdc, other outputs are even possible as semi-standard versions. They are continuously short-circuit proof. The 100°C baseplate allows operation in high-temperature environments.
