Scope applicationThe multifunctional overvoltage, undervoltage, and overcurrent intelligent protector is a comprehensive intelligent protector that integrates overvoltage protection, undervoltage protection, and overcurrent protection. When any line experiences overvoltage, undervoltage, or overcurrent faults, this product can instantly cut off the power supply to avoid unnecessary damage to electrical equipment.When the line returns to normal, the protector…
Scope application
YOG self resetting overvoltage and undervoltage delay protector is a new generation product developed by our company according to market demand. The protector is designed reasonably and adopts advanced manufacturing methods for imported components and domestic components assembly. The product can quickly and reliably cut off the power supply under high voltage impact and undervoltage conditions, protecting household appliances. When the voltage returns to normal, after a delay, it can automatically connect the circuit and restore power supply, effectively protecting appliances from the impact of momentary power on. All functions are fully automated, without the need for dedicated personnel to operate, and dual light indicators are selected.

5. Installation category: Category II
6. Installation method: Adopting international standard guide rails.
PRODUCT FUNCTION
A device that can automatically disconnect and detect the line voltage when the overvoltage and undervoltage in the circuit exceed the specified values, and can automatically close when the voltage in the circuit returns to normal. Mainly used for overvoltage, undervoltage, phase failure, and neutral line protection in household and shopping mall power distribution (single-phase AC230V, three-phase three wire AC400V) lines.
The control circuit adopts a high-speed micro low power processor as the core, magnetic holding relay as the main circuit, and modular standard design. When overvoltage or undervoltage occurs in the power supply line, the protector can quickly and safely cut off the circuit under continuous high voltage impact, avoiding the occurrence of accidents caused by abnormal voltage entering the terminal electrical appliances. When the voltage returns to normal, the protector will automatically connect the circuit within the specified time, ensuring that the terminal electrical appliances operate normally without human supervision.
