YJQGs-100 type 1P+N

Scope application

YJQGs-63/100 automatic reset overvoltage and undervoltage delay protector (photovoltaic specific) is a new generation product developed by our company according to market demand. The protector is designed reasonably and assembled with imported components and domestic * * components, using advanced manufacturing techniques.

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.

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 in household and shopping mall power distribution (single-phase AC230V, three-phase three wire AC400V) lines as overvoltage, undervoltage, and phase failure.

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.
