Electrical Characteristics

1. SPD structure: Inner core part is a metal oxide varistor made with zinc oxide.
2. Rated voltage (Un): The rated voltage of SPD device will be the same with rated voltage of the device being protected.
3. Maximum continuous operating voltage (Uc): 275VAC, Uc should be 15% greater than Un.
4. Frequency: 50/60 Hz
5. Time: MOV≦25ns, NPE≦100ns
6. Voltage protection level (Up): Less than rated impulse withstand voltage of the device being protected.
7. Life expectancy: It takes voltage surge 10000 times within rated discharge current
8. Operating temperature: -5˚C ~ +40˚C, relative humidity: 30~99%, operating altitude: 2000 meter below.
