PEF power factor controller
PEF power factor controller is a new type of intelligent power distribution measurement and control equipment that integrates functions of measurement, protection, switching control, and communication.
Measuring function: power factor, voltage and current, frequency, active power, reactive power, voltage / current harmonic total distortion rate, voltage / current harmonic content rate, temperature, etc.
Protection functions: over-voltage protection, under-voltage protection, over-current protection, small current protection, harmonic over-limit protection, over-temperature protection, parameter power-off protection.
Additional functions: temperature measurement, fault alarm, forced air cooling control, RS485 communication interface.
