The well-regarded EA-PS 9000 series’ flexible output level concept, with the option of high voltages & high currents in one device, is now rounded off with microprocessor-controlling & a digital operating unit. The user-friendly & interactive menu structure offers previously unprecedented functionality. User-profile, function sequences & curves, monitor functions, alarm management almost no wish goes unfulfilled. The ZH-equipment is equipped with a two-quadrant module for the fast & defined unloading of the output voltage (source lowering principle) according to DIN 40839, in order to be able to use the equipment in auto-electronics inspection stations. Thus auto elektronic tests can be accomplished by simulation of the engine characteristic or the auto Hi Fi test
