Solid-on LED lighting/alert

  • 17-Jan-2011 04:13 EST

The UPA-130S series from the Diversified Electronics Division of Marsh Bellofram provides solid-on LED lighting and alert capabilities for monitoring applications requiring enhanced NFPA70E and OSHA safety compliance, instead of the flashing LEDs found on the standard model. The series reduces the risk of electric arc flash by preverifying the electrical isolation from outside of a control panel before its reverification with a meter. The system operates over a standard range of 40 to 750 V ac (30 to 1000 V dc) line-to-line or ground-to-ground, is phase insensitive, and offers high surge immunity protection. When hardwired to the load side of a circuit breaker or main disconnects, it detects stored hazardous ac and dc voltage in any individual phase. After disconnecting power to an enclosure, electricians can preverify voltage isolation while an enclosure door is safely closed. The series offers a potted construction with 6-ft leads and fits a 30-mm knockout.
