Automatic Over/Under Voltage & Overload Protection Device with Adjustable Settings, LED Display & Weather-Proof Cover

The amiciSmart Automatic Over/Under Voltage and Overload Protection Device is designed to safeguard your home appliances from harmful electrical fluctuations. Whether it’s voltage spikes, drops, or overload conditions, this device reacts instantly with a 0.1-second response time, ensuring reliable protection at all times.

With adjustable protection ranges—over-voltage (230–300V), under-voltage (140–210V), and overload current (1–63A)—you can fine-tune the settings to match your specific electrical environment. The auto reconnect feature cuts off the power when voltage goes beyond safe limits and automatically restores supply once conditions stabilize, with a customizable delay of 1 to 500 seconds.

Built with user convenience in mind, the protection values and reconnect time can be fully adjusted. It supports multiple wire thicknesses, making it suitable for a wide range of household and commercial applications. The device also includes a weather-proof cover for safe installation and added durability.

In case of extreme surges above its 440V tolerance, the protection module will safely disconnect and sacrifice itself—keeping your appliances fully protected.
