HI-POT TESTING OF DC to AC Inverter
Most of our AC inverters are Listed by Intertek to conform to UL 458 One of the
requirements of UL 458 is that all AC inverters pass a High Voltage Dielectric Withstand
Test, commonly called the Hi-Pot Test. The voltage applied to the control is usually
equal to 1,000 volts, plus two times the line voltage rating of the inverter. Therefore, the
standard hi-pot voltage for 115 VAC inverter is 1,250 VAC. For 230 VAC or dual voltage
inverters, the hi-pot voltage is 1,500 VAC. This Aims power inverter is hi-pot tested
before it leaves the factory, with a UL Certified hi-pot tester, set to the voltages shown
abov
For UL Listed equipment, UL requires that customers perform a final Hi-Pot test of their
machine with the AC inverter installed. Hi-Pot testing is used to detect any electrical
leakage between live metal components and the frame of the machine that is connected
to earth ground. This helps prevent electrical shock to the user of the equipment should
a live component touch the frame and the user touch the frame and ground at the same
time.
