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)
