ApplicationsUsed in single-phase control system,when the power
supply is abnormal(voltage too high or too low),cut off the power
to protect electrical equipment from damage. Built-in
microprocessors,true RMS measurement,voltage measurement accuracy
≤1%.Measuring frequency 45Hz-65Hz,knob setting,LED indicator shows
working status.Lock function with fault status,DIN rail
mounting.Model Description Model Selection
