DESCRIPTION
DPC71DM48 is a True RMS 3-phase voltage monitoring relay designed for DIN-rail mounting that detects phase sequence errors, phase loss, asymmetry, tolerance deviations, and over/under voltage conditions with separately adjustable setpoints and delay functions ranging from 0.1 to 30 seconds. The relay operates on a supply voltage of 380 to 480 VAC ±15% at 45 to 65 Hz, with a measuring range of 323 to 550 ?VAC for phase-phase voltages and 220 to 277 VAC for phase-neutral voltages. It features two 5 A SPDT relay outputs with 250 VAC rated insulation voltage, mechanical life exceeding 30 million operations, and electrical life of at least 100,000 operations at 5 A and 250 V. The device includes LED indicators for power supply status (green), alarm conditions (red, flashing at 2 Hz during delay), and relay activation (yellow), along with a reaction time of less than 200 ms for phase sequence or total phase loss detection. DPC71DM48 is ideal for industrial applications requiring reliable mains quality monitoring, motor protection, and load management in three-phase power distribution systems.
