The DIN Rail Display Adjustable Over and Under Voltage Protective Device Relay is a smart electrical protection solution designed to safeguard equipment from voltage fluctuations. It continuously monitors power supply and disconnects the load during over-voltage or under-voltage conditions. Featuring an easy-to-read digital display and adjustable protection settings, it ensures precise and reliable control. Its compact DIN-rail mount design allows quick installation in distribution panels. Ideal for residential, commercial, and industrial systems, this relay enhances electrical safety and power stability. Features: Turn off over-voltage protection, press the up button when it reaches 300V Turn off low voltage protection, press the button below when it reaches 150V When off, the product can record Kw h, over-voltage, under-voltage, and over-current value. When the V LED flashes, it means more or less voltage protection When an LED flashes, it means over current protection. Under-voltage protection 2 10V-145 V (adjustable) (default: 170 V) can be disabled Overvoltage protection 230V-300V (adjustable) (default: 270) can be disabled Over-current protection 1A-63A (adjustable) (default: 40A) Reconnection time (delay to time): 3-300s (default: 30 s) voltage meter ammeter energy meter Specification: Brand name : TOMZN Rated voltage: 220V Type : Mini Can be customized : Yes Model number : TOVPD1-63VEA Over Voltage adjustable range : 230-300V adjustable Under voltage adjustable range: 210-150V adjustable Overcurrent adjustable range : 1-63A adjustable Frequency: 50Hz / 60HZ Uses: Industrial electrical panel protection Motor and machinery safety Commercial building voltage monitoring Residential electrical system protection Voltage-sensitive equipment safety Package Include: 1 x Din Rail Display Adjustable Over and Under Voltage Protective Device Relay
