The PST22 , very compact DC-DC converter in an eurocard format, incorporate input and output protec�on and filtering, signalling features,

which are required in most of the severe environment for industrial, railways type of applica�ons. The converter provides significant advantages

such as flexibility of output configura�on, high reliability thanks to the integra�on of Vicor Corp. modules, extremely high efficiency with secon-

dary ac�ve MOSFET circuit for redundancy opera�on, very low ripple and noise levels, input-to-output isola�on, so� start, overtemperature

protec�on, input over/undervoltage lockout, parallel opera�on . The converters wide range of inputs are protected against surges and transients

and EMI filtered. The outputs are coun�nuously short-circuit proof . Series, Parallel and N+1 redundant opera�on are possible through an ac�ve

MOSFET based circuit, improving significantly efficiency thus lowering power dissipa�on and allowing opera�on in high temperature environ-

ment, simplifying connec�on when several converters are connected in parallel without the need of wire connec�on 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 saving cost .
