The PST22 , very compact DC-DC converter in an eurocard format, incorporate input and output protection and filtering, signalling features, which are required in most of the
severe environment for industrial, railways type of applications. The converter provides significant advantages such as flexibility of output configuration, high reliability thanks
to the integration of Vicor Corp. modules, extremely high efficiency with secondary active MOSFET circuit for redundancy operation, very low ripple and noise levels, input-tooutput isolation, soft start, overtemperature protection, input over/undervoltage lockout, parallel operation . The converters wide range of inputs are protected against surges
and transients and EMI filtered. The outputs are countinuously 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 saving cost .
