Marsh Bellofram Diversified Electronics' Hazardous Area Certifications for UPA-130 Series Universal Voltage Alert
The UPA-130 series Universal Voltage Alert is designed to reduce the risk of electric arc flash by pre-verifying the electrical isolation from outside of a control panel before it is re-verified with a meter. It operates over a standard range of 40 to 750 VAC (30 to 1000 VDC) 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, the UPA-130 series flashes upon detection of hazardous AC and DC voltage in any individual phase. After disconnecting power to an enclosure, electricians can pre-verify voltage isolation while an enclosure door is still safely closed. The compact, eight-detector UPA-130 series offers a potted construction with six-foot leads and is designed to fit a 30mm knockout. Its design includes redundant circuitry and the incorporation of long-life display panel LED's for extended use, with components housed in NEMA 4X, 12 and 13 electrical enclosures.
