The safety test of electrical devices must, after having been tested without current and depending on the relevant test standard, be completed by a line leakage measurement with increased rated voltage. Only by means of the line leakage test is it possible to activate the internal controls in case of electro-mechanical devices.
Series AI 5000 offers 3 different techniques. While tester AI 5000A draws its test voltage directly from the power supply, tester AI 5000P applies a safety isolating transformer.
A further and important feature of the testers is the cutting-in.
With testers AI 5001A, AI 5000P and AI 5010D an operating mode change-over is possible without turning off the supply voltage of the DUT.
