Hipot test voltage may be specified as either ac or dc. dan kita bisa sedikit bermain Ideally, so one can test near the rated voltage of the wire insulation without exceeding the rated voltage of the insulation. You are responsible for your actions. They are both screwed to the same metal heatsink. Skip to main content Continue to Site .
