Independent self-resetting over-voltage and under-voltage protector, also known as self-recovery over-voltage protector, over-voltage protector, automatic reset over-voltage protector, over-voltage and under-voltage protector, fully automatic over-voltage protector, single-phase over Undervoltage protector, overvoltage, undervoltage protector, self-resetting overvoltage, undervoltage protector.
Design principle
The control circuit uses a high-speed micro-low-power processor as the core.
The magnetic holding relay is designed for the main circuit and the modularization standard. When the power supply line has overvoltage or undervoltage, the protector can cut off the circuit quickly and safely under the continuous high voltage impact to avoid the accident caused by abnormal voltage being sent to the terminal electrical equipment. When the voltage returns to the normal value, the protector will automatically turn on the circuit within the specified time to ensure that the terminal appliance operates normally under unattended conditions.
