PST21D - 1

AC-DC Conduction Cooled 85-264Vac, 47-440Hz Input voltage ranges , PFC 100-350 Vdc input voltage operation 1 isolated output Active very low inrush current limiting circuit 165*61*35mm very low profile Industrial or ruggedizzed for hard environment Many output configurations available Conduction cooled 100°C baseplate Safety IEC/EN 62368-1, RoHS lead-free-solder compliant RoHS The PST21D, very compact and low profile AC-DC power supply in chassis format, incorporates input filtering, input and output protections, very robust mechanical mounting and connection, optional conformal coating and MIL-STD options required in most of the severe environment for industrial, defense applications. 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 current limitation, overtemperature protection and input over/undervoltage lockout. The PSU is configurable in many output voltages from 2V to 48Vdc, other possibilities are even possible as semi-standard versions, they are countinuously short-circuit proof. The 100°C baseplate operation allows operation in high temperature environment.

Parallel operation & current share Hold up time at 230VAC, 100% load - PST21D-28150 Parrallel operation is possible between different units but there is no active current sharing signal vailable on the PST21D, please use PST21C if needed. Output external circuit has to be used (risk of damage otherwise). Redundant Systems Operation When systems require a very high level of reliability and should work normally in the event of a failure, N+1 redundancy is implemented where N is the number of converter to support power requirement. If one converter fails, the remaining ones still delivers the...

Output Voltage Adjustment (ADJ) A potentiometer at the output side allows output voltage variation from -10% to +10% of Vnom. The TRIM signal allows output voltage to be adjusted by an external voltage 1,15 to 1,25Vmax voltage referred to -OUT. Extended range of adjustment down to -50% can be considered as semi standard product, consult factory. Remote Senses (+S -S) There is no remote sense functionnality integrated in the PST21D for compensation of voltage drop across the connector contacts and the load lines. Remote Sense can be done by an external circuit acting on the TRIM signal....

power system TECHNOLOGY These converters are components, intended exclusively for integration into other equipment by an industrial assembly process or by a professionally competent person. Installation must strictly follow the safety regulations in respect of the enclosure, mounting, creepage and clearance distances, markings of the end-use application. Connection to the system shall be made via the male connector Wurth. The AC/L is internally fused. This fuse is designed to protect the converter against overcurrent caused by a failure, but may not be able to satisfy all requirements....
