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.
