SVP-912 Adjustable Smart Self-Resetting Over/Under Voltage Protector 110V/120V Auto Recovery Switch 40A

The SVP-912 Self-Resetting Overvoltage/Undervoltage Protector is specifically designed to safeguard domestic and commercial electrical appliances from harmful voltage fluctuations. At its core is an intelligent microprocessor that responds instantly to voltage anomalies, automatically cutting off the circuit in the event of overvoltage or undervoltage, and seamlessly reconnecting once the voltage returns to a safe level—all without the need for manual intervention, giving you complete peace of mind. The device supports dual voltages of 110V and 120V and is equipped with adjustable threshold settings to adapt to various mains supply environments. With a robust current rating of 40A, it can easily handle high-power appliances such as air conditioners, refrigerators and water heaters. The flame-retardant PC casing is heat-resistant and impact-resistant, whilst the sensitive built-in relay and overcurrent protection provide multi-layered safety safeguards, ensuring long-lasting and stable operation. Designed specifically for standard DIN rail mounting, the unit is simple to install, and its clear LED indicators display the operating status in real time. The SVP-912 is ideal for domestic distribution boards or small commercial premises, providing an efficient and reliable voltage protection solution.
