The Model DPR350C DIN rail mount voltage phase monitor from the ATC Diversified Electronics division of Marsh Bellofram 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.
The Model DPR350C DIN rail mount voltage phase monitor is packaged in a 35mm wide din-rail mount housing and features a three-digit LCD.
The self-powered DPR350C 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 consist of two SPDT relays with a contact output rating of 5 amps at 250VAC. The Model DPR350C is also UL-approved and CE-certified.
