Product Overview
Features
- 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)
