TECH NOTE: We get numerous calls from users who are looking for AC hipot testers with high output current capabilities. In almost every case, the user actually needed a DC hipot tester. When hipot testing products that incorporate EMI filters (for EMC regulations), you need to use DC, not AC! 

With AC, the Y capacitors in the EMI filter will conduct current, causing false failure indications ａnd possibly damaging these capacitors. Most "high-tech" standards anticipate this ａnd permit DC testing at 1.414 times the AC test voltage. This includes IEC950, IEC1010, ａnd IEC601 based Standards.
