DPC02DM49, Control Relays and Three-Phase Control Protection. multifunction, TRMS measurement phase-phase, phase-neutral Model DPC02, DPC02DM49, Voltage control relays of three-phase or three-phase+ neutral lines for detection of incorrect phase sequence, phase loss, maximum or minimum voltage level (with independent adjustment), maximum or minimum frequency level with built-in delay function. Power scales from 208 to 690 WL Covered by four multi-voltage relays. Its most frequent field of application is that of generators., DPC02DM49, Connected to the 3 phases (and neutral), the DPC02 equipment operates when the 3 phases are present at the same time and the phase sequence is correct. Voltage level and frequency level control: If one or more phase-phase or phase-neutral voltages are above the pre-selected max level or below the min. level, the red LED starts flashing 2 Hz and the corresponding output relay disconnects after the adjusted delay period. If the network frequency falls outside the selected frequency symmetric band within the rated frequency scale, the red LED starts a 2 Hz flash and the corresponding output relay disconnects after the adjusted delay period. Example 1 (Generator control - 2 SPDT relays - phase voltage) The relay controls the phase loss, the correct sequence of phases, the max and min voltage level and the system frequency. A voltage fault is detected by relay 1 and a frequency failure is detected by relay 2. Example 2 (Network control - DPDT relay) The DPC02 equipment controls the phase loss and the correct sequence of phases, the max. and min. voltage level and frequency. Each fault is detected by relays 1 and 2 at the same time, allowing 2 independent simultaneous outputs.
