PST 22 Series

The PST22 is a compact DC-DC converter in an eurocard format, incorporates input and output protection and filtering, signalling features, which are required in industrial and railway applications.

The PSU provides high reliability thanks to the integration of Vicor Corp. modules, high efficiency with secondary active MOSFET circuit for redundancy operation, very low ripple and noise levels, input-to-output isolation, soft start, over temperature protection, input over/under voltage lockout, parallel operation.

The wide input range converters are protected against surges and transients and EMI filtered. The outputs are continuously short-circuit proof. Series, parallel and N+1 redundant operation are possible through an active MOSFET based circuit, improving significantly efficiency thus lowering power dissipation and allowing operation in high temperature environment, simplifying connection when several converters are connected in parallel without the need of wire connection between the converters to ensure good current sharing.

LEDs at the front panel and an isolated Powergood signals indicate the status of the converter. V3 output can be either configured in high power version up to 150W with a DC-DC Vicor module or in a low power version up to 30W with switching regulator. A 4th non isolated output (-12V 1A) is also available.
