The Novatek OM-310 3-phase Power Limiter provides protection against over-voltage, over-current and phase-related faults, including voltage surges, phase loss, incorrect phase sequence, phase coincidence and phase/line voltage imbalance. For each type of fault, the user can set the unit to enable or disable automatic load resetting via a magnetic starter or contactor.
Additionally, the OM-310 output can be used to control additional relays for warning alarms, back-up systems, etc.
The ОМ-310 can communicate control and parameters with a PC via RS-485 interface according to MODBUS protocol or via RS-232 interface.
