| Datasheet | Download Datasheet |
The Macromatic PC1MDUL is a 60 mm DIN Rail phase monitor relay with 1C SPDT output and rated 5 A at 250 V AC, driven by a (30...660)V AC input.
It watches all three phases for phase loss, phase reversal, phase unbalance, undervoltage and overvoltage, measuring true RMS with full-wave monitoring.
The undervoltage trip point is adjustable from 80 to 95% of the line voltage setting, and resets at +2% of the trip setting.
It drops out 100 ms fixed after a lost or reversed phase, 0.3...30 s adjustable after an undervoltage and re-energises 1...300 s adjustable after the fault clears.
It has DIN Rail/Panel Mount mounting and screw terminals.
