Notes
1. The sinusoidal voltage is assumed as the normal operating condition. If a non-sinusoidal voltage is present, type selection should be based
on multiplying the peak voltage by a factor of 0.707.
2. The voltage measured at 1 mA meets the requirements of “paragraph 4.3 of CECC specification 42000”.
