Automatic reset over and under voltage protector: Uses a single-chip microcomputer to collect voltage and stipulate a working voltage range. When the voltage exceeds the standard working voltage, it protects the product to prevent household appliances from being damaged.
Classification of self resetting overvoltage and undervoltage protectors:
Divided by the number of poles: a、Single-phase self resetting overvoltage and undervoltage protector, i.e. 1P+N, Three phase four wire self resetting overvoltage and undervoltage protector c、 Three-phase three wire self resetting overvoltage and undervoltage protector,
Control circuit division a、Analog circuit b、Digital circuit
At present, all products of our company use digital circuits, which have the advantages of good anti-interference and high accuracy According to the rated current of the product: a、 Single phase 32A, 40A, 50A, 63A, 80A b、 Three phase four wire: 32A, 40A, 50A, 63A, 80A, 100A
Divided by working voltage and frequency: a、50Hz AC230V/400V b、60Hz AC110V/220V
According to the instructions: a、 Indicator light display b. LCD or LED display
