Descrip�on
Safety IEC/EN 60950-1, RoHS lead-free-solder compliant
RoHS
The PST21A, 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 environment for industrial, defense appli-
cations. 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, input over/undervoltage 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 countinuously short-circuit proof. The 100°C baseplate allows operation in high temperature
environment.
