Would anyone tell me why IEC950 allows a capacitor having a discharge means in a time constant not exceeding: ---, i.e. during one time-constant the voltage decays to 37 % of its original value?
The reason of my question is: If the original voltage is 120 V ac, 37 % or its original will exceed 60 V dc which I think is hazardous in terms of voltage. Is there any implied consideration in IEC950 for energy level other than voltage? Thank you for your help in advance. Mike Gomi [email protected] QA Dept. A-Pex International Co Ltd
