Adjustable Voltage Protector Self Resetting Smart Over Under Voltage Protective Device with Power Display AC230V 1‑63A

Feature: 1. Circuit Guard: This protector provides overvoltage guard, undervoltage guard, and voltage display (voltage measurement), supports manual adjustment of overvoltage, undervoltage, and overcurrent guard values. 2. Main Purpose: Can prevent the frequent on off of unstable voltage from causing additional damage to electrical devices. With delayed power on function, after the voltage stabilizes for 1‑500s, it automatically restores power supply. 3. Clear Display: This smart protective device provides voltage, current, and KWH displays, ensuring clear and intuitive readings, greatly improving operational convenience and work efficiency. 4. Multiple Functions: This self resetting overvoltage undervoltage protector has functions such as reset mode selection, fault inquiry, and factory recovery, meeting the needs of more scenarios for use. 5. Flame Retardant PC: The voltage protector shell is made of excellent PC material, which is environment friendly, flame retardant, safe and reliable, can be used in various environments, has a long service life.
