The third part serves for the phase sequence indication. A voltage divider is provided between two of the test prods., and a series circuit consisting of a resistor and a capacitor is between at least one of the two test prod. and the third, with the capacitor connected to the third ...
24Vdc power supply (DIN Rail Mount). It passed all the tests, except it failed the Phase-to-PE HiPot test at around 1000V. I tried both AC and DC voltage and tried connecting it from a single phase to PE and tried all phases connected together to PE. I tested a second power supply...
