What is a way to bypass this ground leakage safety. ![]() The unit works fine in smaller cells but I am working with a large one, 4x5 meters it is for an art installation and I need the high voltage to accelerate the particle migration which is why I am using an electrophoresis power supply. I understand that the supply shuts down if there is a leakage of more than. I've had the same problem with the interlock which I solved but I am also having a problem with ground leakage. I can't blame them for having all these safety features considering they are for use on "wet bar" biology lab benches. The intended electrophoresis cell loads are expected to be floating from ground. The power supply has an internal center-tap tied to ground. In this case, leakage is 'ground fault current' detected as the difference between the current out the positive terminal vs. "Leakage" can shut down the output, on mine there is a red led that goes on when the ps is cut-off due to leakage. ![]() I only have one electrophoresis power supply, but it has another safety feature to be aware of.
