This intelligent protecting switch is mainly designed for monitoring and protecting the voltage in the power system. Effectively protects the power system and equipment from overunder voltage. It is suitable for a 220 V power system. It has overvoltage and undervoltage protecting functions, and the over-voltage, and under-voltage thresholds of this product can be set by yourself. With a self-resetting function, the device can automatically return to a normal working state after a fault or abnormal situation without manual intervention.
Features:
Utility Power Equipment: This intelligent protecting switch is mainly designed for monitoring and protecting the voltage in the power system. Effectively protects the power system and equipment from overunder voltage. It is suitable for a 220 V power system.
Automatic Phase Switching: This means that the device can simultaneously receive inputs from three phases and output voltage from one phase. This is useful for power systems that need to monitor multiple phase voltages simultaneously. The device can automatically switch the phase of the input to keep the output voltage stable.
Uninterrupted Digital Display: This feature allows the unit to display voltage values in real-time without manual intervention.
Adjustable Over- and Under-voltage Protection: You can adjust the overvoltage and undervoltage protecting thresholds as your need to prevents the power system from being damaged by overvoltage or undervoltage.
Zeroline-loss and Phase-loss Protection: It can automatically cut off the powersupply when zeroline loss or phase loss in the power system to prevents equipment damage.
With Self-resetting Function: The device can automatically return to a normal working state after a failure or abnormal situation without manual intervention. This function can greatly improve the availability and reliability of the device. 1-500 seconds self-reset time is adjustable.
Input Phase Priority Selection: The changeover switch can set which power resource is the priority, when the priority phase recovers to the normal voltage, the phase transfer switch will change back to a priority power resource.
Wide Applications: Suitable for a variety of occasions, such as rental houses, shopping malls, schools, factories, etc. Mainly used in all kinds of equipment and systems that need powersupply, such as industrial production equipment, elevators, air conditioning systems, powersupply systems, and so on.
