Features: This power socket features a clearly digital screen, displaying real-time voltages. With automatic power off and auto recovery, it ensures safe operate by protecting against over-voltages, under-voltages, short circuits, and overloads (3680W for maximums). Equipped with adjustable protections settings, this voltages protector automatically shuts off during unsafe voltages conditions (over/under-voltages) and restores power once stable. Features secure anti-misinsertion protections to prevent accidental access. The large digital display allows easy voltages tracking for enhanced safety. With manual power off option and delay protections, it’s a versatile solution for safeguarding appliances and electrical systems.
