DPC01 - PPC01 True RMS 3-Phase voltage monitoring relay Benefits Wide voltages and frequency ranges. Working in systems from 100 to 690 VAC and 50 to 400Hz. Adjustable voltage levels, asymmetry, tolerance and time delay. To allow a correct response to real alarm conditions. Output and status LED indication. For quick troubleshooting. Two mounting versions. Available for DIN-rail (DPC01) and Plug-in (PPC01) mounting. Adjustable power ON delay. To avoid nuisance tripping at start-up. Ultra-high harmonic immunity. For very noisy environments. Description DPC01 and PPC01 are 3-phase mains monitoring relays. They operate on 3P and 3P+N systems, monitoring phase loss and phase sequence, overvoltage and undervoltage, voltage asymmetry and torelance. Power supply provided by the monitored mains. Two independent delay functions, up to 30s, for over/under voltage and asymmetry/tolerance alarms. Applications DPC01 and PPC01 offer solutions for a wide range of applications: lifts, escalators, HVAC, material handling, pumps, compressors and mobile machinery installations. Main functions Monitoring 3-phase mains with 3 wires (3P) or 4 wires (3P+N). Detection of the correct phase sequence, phase loss, asymmetry and tolerance. Front dial adjustable overvoltage, undevoltage, asymmetry and tolerance setpoints. Time delay. Two changeover relay outputs. 06/08/2020 DPC01-PPC01 DS ENG Carlo Gavazzi Controls S.p.A. 1DPC01 - PPC01 Structure A A N L1 L2 L3 N L1 L2 L3 10 14 10 14 E 10 14 10 14 E 10 14 10 14 E 6 18 6 18 6 18 6 18 6 18 6 18 222% 222% 222% 222% 2 22% 2 22% B / B / B / AL 1 3 1 3 AL 1 3 1 3 1 3 1 3 A+D 0.3 10 0.3 10 0.3 10 0.3 10 0.3 10 0.3 10 AL 30s 0.1 30s 0.1 0.1 30s 0.1 30s 0.1 30s 0.1 30s DELAY1 DELAY2 DELAY1 DELAY2 DELAY1 DELAY2 F F F C C C DPC01 DPC01 400HZ PPC01 16 18 15 26 28 25 D Element Component Function A Input terminals Connection of the line voltages (neutral when present) Yellow for relay output status B Information LED Red to signal alarm status Green for device ON C DIP-switches Setting the nominal voltage, type of mains, power ON delay D Output terminals 2 x SPDT relay outputs E Setpoints dials Overvoltage/asymmetry and undervoltage/tolerance setpoints adjustment F Delay time dials Setting the alarm ON delay time 06/08/2020 DPC01-PPC01 DS ENG Carlo Gavazzi Controls S.p.A. 2 DPC01 3-phase monitoring relay DPC01 3-phase monitoring relay PPC01 3-phase monitoring relay
