n Performance Characteristics
Characteristics Standard Test Condition Test Methods Electrical measurements (initial/after tests) shall be conducted at temperature of 5 to 35 C, relative humidity of maximum 85 % The voltage between two terminals with the specified measuring current CmA DC applied is called Vc or VCmA. The measurement shall be made as fast as possible to avoid heat affection. The recommended maximum sinusoidal wave voltage (rms) or the maximum DC voltage that can be applied continuously. The maximum voltage between two terminals with the specified impulse current (8/20 s). The maximum power that can be applied within the specified ambient temperature. Maximum energy at less than 10 % of varistor voltage change when the standard impulse (2 ms) is applied one time. Maximum current at less than 10 % of varistor voltage change when impulse current (8/20 s) is applied two times continuously with the interval of 5 minutes. VCmA at 85 C VCmA at 25 C 1 60 100(%/C) VCmA at 25 C The change of Vc shall be measured after the specified impulse is applied 10000 times continuously with the interval of 10 seconds at room temperature.
