*1. AC for 1 minute, R.H. = 40 ~ 60%
Isolation voltage shall be measured using the following method.
(1)Short between anode and cathode on the primary side and between collector, emitter and base on the secondary side.
(2)The isolation voltage tester with zero-cross circuit shall be used.
(3)The waveform of applied volttage shall be a sine wave.
*2. For 10 seconds.
