Introduce
Self resetting overvoltage and undervoltage protector is an intelligent electrical protection device widely used in single-phase and three-phase power supply systems. It can automatically monitor the voltage status of the power grid and provide reliable protection under abnormal conditions.
KP2-VA Overvoltage And Undervoltage Protector
The KP2-VA self-resetting protector monitors single-phase power (80V-400V), safeguarding equipment from overvoltage (230-300V) and undervoltage (210-140V) faults for enhanced system reliability.
Key Features
- Overvoltage protection: When the voltage exceeds the set range (such as single-phase 230-300V, three-phase 390-500V), the circuit will be automatically cut off.The default overvoltage protection value is 280V (single-phase)/overvoltage protection action time is adjustable from 0.1-30s.
- Undervoltage protection: When the voltage is below the set threshold (such as single-phase 210-140V, three-phase 370-260V), the protection mechanism is activated, and the default undervoltage protection value is 160V (single-phase).
- Overcurrent protection: Supports adjustable protection values of 0.5-63A, with continuous overcurrent protection times set (1-20 times/OFF).
- Self recovery function: After the fault is eliminated, the power supply will be automatically restored with a delay time of 1-600S, which can be set.
- Multiple Display: Real time display of parameters such as voltage, current, and battery level, with some models supporting power factor measurement.
Applications
- Residential power distribution system protection
- Industrial equipment power protection
- Power monitoring in commercial premises
- Protection of important load equipment
This series of products adopts modular design, with fast response speed (protection action time as short as 0.1S), high measurement accuracy (voltage error ≤ 2%), flexible settings, etc., which can effectively prevent equipment damage caused by abnormal grid voltage and ensure electrical safety. All models have power-off memory function, and the set parameters can still be maintained after power-off.
