Over-Voltage, Under-Voltage Self-Recovery 3 Phase Protector

1. General IntroductionThe Model SRO-125 self-recovery over-voltage and under-voltage delay protector can quickly and reliably cut off the power supply under high-voltage shock and under-voltage conditions to protect electrical appliances. When the voltage returns to the normal value, the circuit can be automatically turned on and the power supply will be restored after delay, which can effectively protect the electrical appliances from the impact of the power supply momentarily. All functions are fully automated with no special person operation is required. Two-color light-emitting diodes are selected. The power indicator is green and the protection indicator is red.2. Main technical parameters SpecificationRated Current(A)Rared Voltage(V)Rated Frequency(Hz)Overvoltage Start Value(V)Normal Voltage Start Value(V)Undervoltage Start Value(V)Two phase overvoltage20,25, 32,40,50,63,80,100,125230VAC50,60275±5240-260170±5Three phase overvoltage with lack of phase/ Three-phase four line overvoltage with lack of phase380VAC460±15420-440300±15 SpecificationNormal Voltage Start Value(V)Overvoltage and Undervoltage start time(S) Power Consumption(W)Electrical Machinery LifeTwo phase overvoltage250,190≤60S100000 timesThree phase overvoltage with lack of phase/ Three-phase four line overvoltage with lack of phase340, 440
