Rhomberg AP235 3Ph+N Supply Monitoring Relay (OV & UV contacts)

AP234 monitors 3 Phases only, AP235 monitors 3 Phases and Neutral

Protection of phase failure & incorrect phase sequence

DIN rail mount.

Fail-to-safe design.

Combined overvoltage and undervoltage monitoring with phase failure or sequence detection

Monitoring of own supply voltage (3 phase).

Separately adjustable setpoints: over-voltage, (5 to 20%) and, under-voltage (-5 to -20%).

Separately adjustable response times on trip & recovery (0.1 to 10 seconds).

Fixed hysteresis: 2%.

Adjustable start-up delay for disabling latching 0.1 to 10 sec.

Selectable latching (ie manual or auto reset).

LED indication of Relay ON and fault type.

2 x 10A SPDT relay outputs (1 for Overvoltage, 1 for Undervoltage)
