Automatic Voltage and Current Protector Socket LED Display Multifunctional Refrigerator Protecting Socket with Automatic Reset Function 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. 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. Flameretardant plastics, high-temperature resistance, safer to use. Nickel-plated brass plate, rustproof and low heat, with high conductivity. 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. It can instantly cut off the powersupply when the line has an overvoltage or undervoltage overcurrent fault, so as to the electrical equipment from being damaged. Voltage measurement accuracy ≤1%. 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. Automatic reset to prevents failure for a long time. Quick response to prevents the danger of over voltage and under voltage. And the recovery time is adjustable. 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 plugs. This kind of socket is especially suitable for high- electrical appliances such as refrigerators, which can effectively these electrical appliances from voltage or current fluctuations.
