| Datasheet | Download Datasheet |
The Macromatic PCPU is a Plug-In phase monitor relay with 1C SPDT output and rated 10 A at 277 V AC, 7 A at 30 V DC, driven by a (190...500)V AC input.
It watches all three phases for phase reversal, measuring true RMS with full-wave monitoring.
It drops out 100 ms fixed after a lost or reversed phase and re-energises 1 s fixed after the fault clears.
It has Socketable mounting and Plug In terminals.
