Selection Notes

The 520782-hour MTBF at 40 degrees C positions this unit for continuous-duty cabinets where unplanned downtime is costly. Screw terminals instead of push-in connectors suit installers standardizing on ring-lug or ferrule termination across a panel. Output voltage trims from 46 to 56 V via the front potentiometer, useful when compensating for cable drop to a distant 48 V load, and the relay-based 48 V OK contact (60 V DC/0.3 A) can drive a PLC input directly for supervisory wiring.
