Protection Device: Overvoltage and undervoltage protection devices are produced by professional production lines, and professional protection devices can be used safely. Automatic recovery: When the circuit is overvoltage, undervoltage or overcurrent, the voltage protector can cut off the power supply instantly to protect the electrical equipment from damage. When the line voltage returns to normal, the protector can be automatically reset, without the need for manual operation. Overload protection: After the overcurrent exceeds 5 times within the specified time, the protector will not automatically restore the power supply. It is necessary to manually press "SET" to unlock the power supply, which can effectively protect the frequent opening and closing caused by the overcurrent not released in time and avoid damage to the equipment. Reliable material: The current protection shell is made of high-quality material, high temperature resistance, insulation protection, ultra-low power consumption and long mechanical life. Do not touch the live parts after power-on to avoid electric shock. Scope of application: The voltage stabilizer is suitable for users or loads with single-phase AC voltage of 230V, 50/60Hz and rated working current of 63A and below. Mainly used for overvoltage, undervoltage or overcurrent protection of distribution lines in residential cabinets, or for the protection of single-phase electrical equipment. Tips: 1. The phase conductor must meet the relevant current standard value, and the load current must not exceed the maximum protection current value of the protection device. 2. The neutral wire N must not be misconnected and must be safe. The neutral line N of the protection is directly connected and there is no disconnection function. 3. After turning on the product, do not touch the live parts to avoid electric shock. 4. This protection has no insulation and short circuit protection. Please use a small circuit breaker in the front to protect against insulation and short circuit. Please disconnect the front circuit breaker when repairing the circuit. If the circuit breaker is not used, the short-circuit current cannot be interrupted when there is a short-circuit fault at the input or output of the circuit breaker. 5. Because the protector has a self-resetting function, after the overcurrent protection and disconnection of the protector, immediately remove the electrical load device and check the circuit, otherwise the protector will frequently turn on the electrical load device, which may be due to long-term frequent switching on and off Turn off to damage the electrical appliance and the protection itself. 6. Please note! If the undervoltage cut-off time is greater than 0.3 seconds, the protection will not open after the power failure. (The MCU power failure will not work after a power failure of 0.3s) 7. After the overcurrent exceeds 5 times within the specified time, the protection lock will not automatically restore power. You need to manually press "SET" to unlock the power supply, which can effectively protect the frequent opening and closing caused by not releasing the overcurrent in time. damage to the device.
