Dual LED display adjustable voltage current protector is suitable for single-phase operating current 220V, 50/60Hz, 63A. It is mainly used for overvoltage, undervoltage or overcurrent protection of single-phase electrical equipment distribution lines. Its main feature is that when the circuit has overvoltage or undervoltage, overcurrent problems, the product can cut off the power supply instantly to protect the electrical equipment from damage. In addition, the protector can automatically turn on the 'food. when the circuit voltage returns to normal. The overvoltage, undervoltage and overcurrent values of this product can all be configured by yourself and can be adjusted according to local practical conditions. Features: Voltage and Current Protection - Turn off the power when the circuit has overvoltage, undervoltage or overcurrent. Protect your home electrical equipment from damage. Automatic reconnection - Turn on the power when the circuit voltage and current return to normal. Adjustable - Overvoltage value range 230V-300V, range of undervoltage values 140V-210V, overcurrent value 1-63A Fault recovery delay time adjustable from 1 to 600 seconds Dual LED display - Two digital seleprate LED displays can display the actual voltage, current independently for easier and clearer reading, can be used as voltmeter and ammeter. Customizable - The overvoltage, undervoltage and overcurrent values of this product can all be set up by yourself and can be adjusted according to local practical conditions.
