DESCRIPTION
DPB02CM44 is a True RMS 3-phase voltage monitoring relay designed for DIN-rail mounting that monitors 3-phase mains systems for phase loss, phase sequence errors, and voltage asymmetry. It operates on 208 to 480 VAC (±15%, 177 to 552 V) at frequencies from 50 to 400 Hz (±10%), with power supply derived directly from the monitored mains and consumption less than 2.5 VA. The device features front dial adjustable voltage asymmetry setpoint (2 to 22%), configurable alarm delay up to 30 seconds, and a changeover SPDT relay output rated at 8 A @ 250 VAC (AC15: 2.5 A @ 250 VAC). It supports both 3-wire (3P) and 4-wire (3P+N) mains configurations with selectable power-on delay (1 s or 6 s) via DIP switches, and includes status indication through green (power), red (alarm), and yellow (relay output) LEDs. This relay is ideal for industrial power distribution systems, motor protection circuits, and critical load monitoring applications where mains quality assurance is essential.
