This voltage protector is made of PC material, flame-retardant, with high impact resistance, wear resistance, and excellent durability. It features a high-quality chip control system that ensures reliable performance and helps protect household appliances. The unit offers multiple protection functions, time delay, and automatic power cutoff. It includes a child safety lock and an internal shutter design to help prevent accidental insertion and reduce the risk of electric shock.Features: Premium Material: Constructed from PC material, flame-retardant, with high impact resistance, wear resistance, and long-lasting durability. High-quality Chip: Equipped with a high-quality chip for stable operation and enhanced protection of home appliances. Easy to Use: Plug-and-use design for convenient and straightforward operation. Safety Lock: Includes a child safety lock and built-in shutter to help prevent accidental contact and electric shock. Multiple Protections: Provides protection against over-voltage, under-voltage, and overload conditions. Offers protection against electrical faults due to voltage fluctuations. Automatic Off: Automatically cuts off power when internal temperatures are too high. Delay Function: Features a 5-6 minute delay that helps protect sensitive electronics such as refrigerators and televisions. Voltage Protection: Operates within a voltage protection range of 170V–260V, helping ensure safer electrical usage. High Compatibility: Suitable for use with various indoor electronic devices, including household appliances, lighting, and holiday decorations. Operation: 1. After connecting to power, the yellow light turns on when the voltage is between 175VAC and 260VAC. After approximately 5 minutes of delay, or by pressing the ON/OFF button, the green light stays on and power output begins. 2. If the voltage is below 175VAC or above 260VAC upon connection, the device enters protection mode. The red light stays on and no power is output. 3. While in protection mode (red light on), if the voltage rises above 190VAC or drops below 240VAC, the yellow light turns on. Power resumes after about 5 minutes of delay. 4. The ON/OFF button only functions when voltage is within the normal range. It has no effect during protection mode. 5. Once in normal operation, if voltage becomes unstable or falls outside the acceptable range, the device immediately enters protection mode and stops power output.
