Under Over Voltage Protection Device ZMGQ1

What Is Under Over Voltage Protection Device ?

An Under Over Voltage Protection Device is an electrical protection equipment that actively monitors the voltage status of the power grid and automatically cuts off the circuit when the voltage is abnormal. Its core function is to block the damage caused by “excessive voltage (over-voltage)” or “insufficient voltage (under-voltage)” to electrical equipment, circuits and personal safety, and it serves as a “safety barrier” between the power grid and electrical loads.

Advantages of Under Over Voltage Protection Device

• Precisely protects electrical equipment and extends its service life.
• Prevents equipment damage caused by over-voltage breakdown.
• Prevents equipment from “operating with faults” due to under-voltage.
• Reduces equipment maintenance and replacement costs.
• Prevents circuit overload and fire hazards.
• Reduces the risk of electric leakage and protects personal safety.
• Provides 24/7 real-time monitoring with fast response speed.
• Automatic reset when voltage returns to normal (for some models).
• Simple installation and commissioning.
• Suitable for a wide range of fields.

How Does an Over/Under Voltage Protector Work?

Its function is to continuously monitor the power supply voltage. When the voltage goes beyond the safe operating range of the equipment or circuit, it will automatically cut off the circuit to prevent damage to the equipment. Once the voltage returns to a stable state, it will then restore the circuit power supply automatically or manually.
