Intelligent Protection for AC Power Circuits
The Adjustable Over and Under Voltage Protector is designed to protect electrical equipment and AC distribution circuits from abnormal voltage and current conditions.
The device continuously monitors circuit voltage and current and provides automatic protection against overvoltage, undervoltage and overcurrent. When any value exceeds the preset protection threshold, the device disconnects the circuit automatically to help prevent damage to connected equipment.
After the power supply returns to the normal range, the device can reconnect automatically based on the selected settings and adjustable reconnect delay.
A built-in digital display allows users to monitor voltage and current values clearly, while the adjustable setting function makes the product suitable for different application requirements.
Designed for DIN rail installation, this protector is widely used in residential, commercial and industrial AC distribution systems where reliable automatic power protection is required.
