Lumintech AVP (Automatic Voltage Protector) is a multifunctional single-phase two-wire power supply system or monitoring and protection device for electrical equipment. It integrates single-phase voltage display, overvoltage protection, undervoltage protection, and electrical short-circuit protection. It can be used to monitor the electricity supply voltage and will cut-off the power supply for abnormal voltage conditions that may endanger the safe and reliable operation of the power supply system and equipment. This allows the control system to respond appropriately before the appliances are damaged.
