Safety IEC/EN 60950-1, RoHS lead-free-solder compliant

The PST14, very compact DC-DC converter in chassis mount format, incorporates input filtering, input and output protec�ons, very robust

mechanical moun�ng and connec�on, op�onal conformal coa�ng, required in most of the severe environment for industrial, railways, defense

type of applica�ons. The converter provides high reliability thanks to the integra�on of Vicor Corp. modules, high efficiency, input-to-output

isola�on, so� start, overtemperature protec�on, input over/undervoltage lockout. The converters wide range of inputs are protected against

surges and transients and EMI filtered. The outputs are coun�nuously short-circuit proof .The 100°C baseplate opera�on allows opera�on in high

temperature environment.

The output can be configured in many different output voltages from 3V3 to 48Vdc, can be put in series and parallel, others possibili�es are even

possible as semi-standard versions.

Wide range of accessories (see page 16) like input & output Bus bars, N+1 oring diodes, parallel cables are available to simplify mul� units

assemblies. Military op�ons (M) make it suitable for MIL STD compliance.
