The Automatic Reset Over/Under Voltage Delay Protection Device (special for photovoltaic use) is a new generation product developed by our company to meet market demands. The protector is designed reasonably, utilizing imported components and domestically assembled devices, and is manufactured with 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 after a delay, restoring power supply. It effectively protects appliances from the impact of instantaneous power-on. All functions are fully automated, requiring no manual operation, and features dual-light indicators.
