Feature: 1. 【Voltage Current Protector】: It can instantly cut off the powersupply when the line has an overvoltage or undervoltage overcurrent fault, so as to protect the electrical equipment from being damaged. Voltage measurement accuracy ≤1%. 2. 【Premium Material】: Flameretardant engineering plastics, high-temperature resistance, safer to use. Nickel-plated brass plate, rustproof and low heat, with high conductivity. 3. 【Compact Structure】: Portable design, small size, and compact structure, it does not occupy too much space. Plugs-and-plays type, no need to install, convenient and quick. 4. 【Digital Display】: LED display panel, large font, the actual voltage, and actual current are highlighted and easy to read, you can see the data clearly at a glance. 5. 【Multiple Protections】: Support under-voltage protecting, over-voltage protecting, over-current protecting, surge protecting, etc. Automatic recovery, and with recovery time adjustment function. Built-in 16A magnetic relay, the high current impact will not burn. 6. 【Automatic Reset】: Automatic reset to prevents power failure for a long time. Quick response to prevents the danger of over voltage and under voltage. And the recovery time is adjustable. 7. 【Safety Socket】: A safety protecting door prevents the child from the danger of inserting fingers or small objects, the safety door is equivalent to the pressure produced by 8.5kg weight. Specification: This is a kind of socket with an automatic voltage and current-protecting function, which prevents electrical equipment from being damaged due to excessive voltage or current, which is suitable for EU standard plugs. This kind of socket is especially suitable for high-power electrical appliances such as refrigerators, which can effectively protect these electrical appliances from voltage or current fluctuations.
