Applications
Used in home and villa 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.
Features:
Built-in microprocessor, true RMS measurement, voltage measurement accuracy ≤1%.Knob setting, LED indicator shows working status. Use(magnetic latching)relay to achieve products low-power. DIN-rail mounting.
