The Automatic Over/Under Voltage Delay Protection Device (Specialized for Photovoltaic) is a new generation product developed by our company in response to market demands. The protector is well-designed, incorporating imported components and domestically assembled devices, and is manufactured using advanced production techniques.
The product can quickly and reliably cut off power under high-voltage surges and under-voltage conditions, protecting household appliances. Once the voltage returns to normal, it can automatically reconnect the circuit and restore power after a delay, effectively protecting appliances from power surges upon immediate power-on. All functions are fully automated, requiring no manual operation, and features dual-light indicators.
