ATC DPR350C Phase Monitoring Relay, SPDT, 5 A, DIN Rail, Screw, 250 VAC

DPR350C is a DIN rail mount voltage phase monitor. It is designed to monitor under voltage, over voltage, frequency shift, imbalance, phase loss and phase sequence for three-phase, three-wire and three-phase, four-wire 460VAC applications. It is packaged in a 35mm wide din-rail mount housing and features a three digit LCD display. Available onboard functions include true RMS measurement, restart and fault delays, adjustable switching hysteresis, as well as two separate alarm relays and auto/manual reset. This self-powered device has an operating range of 280 to 600VAC (L-L) for 3 phase 3 wire systems and an operating range of 160 to 300VAC (L-N) for 3 phase 4 wire systems. Output specifications of the DPR350C DIN rail mount voltage phase monitor consists of two SPDT relays with a contact output rating of 5 amps at 250VAC. The model DPR350C is also UL approved and CE certified.
