Key Functions
- Overvoltage Protection: Adjustable overvoltage threshold, power cut when voltage exceeds preset value
- Undervoltage Protection: Trip when voltage below setting value, protect appliances from low voltage damage
- Overload & Overcurrent Protection: Adjustable current limit, break circuit under overload
- Self-reset Delay: Configurable delay time after power recovery, prevent frequent on/off caused by voltage fluctuation
- Dual Digital Display: Simultaneously display real-time voltage(V) and current(A)
- Parameter Setting Buttons: SET + UP/DOWN keys to adjust protection thresholds easily
- Fault Indication: Show fault type after tripping for quick troubleshooting
Application
Household main distribution box, whole house appliance protection
Shops & office single phase power circuit
Single-phase photovoltaic / residential PV system
Water pump, water heater, air conditioner and other high-power single-phase loads
Rental house & construction site terminal power distribution
AVP-40 and AVP-63 belong to the same series single-phase DIN rail digital self-resetting protector, AC220V. They provide overvoltage, undervoltage and overcurrent protection with adjustable thresholds and dual display for voltage & current. The core difference is rated current: AVP-40 is 40A for medium-small power incoming circuit; AVP-63 is 63A with higher load capacity for high-power single-phase loads and heavy-current main circuit.
