The new LCD-Display offers the total overview of all adjustments and measurements. Continuously the adjusted values of AC-Voltage, DC-Voltage, Current, Frequency and PhaseAngle for switching the output on and off, are displayed. In the range of the measurements the true RMS value of the Voltage, the true RMS value of the Current, the Peak-Current, the Real Power, the Apparent Power and the Power Factor are continuously displayed and refreshed. Not only the new display makes the AC-Source easier to operate, also the new operation features make it real simple to use the AC-Source Type EAQ. By pressing a button the fixed frequency can beselected between 50, 60 and 400 Hz and also variable frequency is available. To change between standard sine wave output and user curve it is only a button to press. The last adjustments before switching the unit off at the main switch will be saved and are available by pressing the button POL (PowerOnLast) after switching the unit on again. tage, the Current, the Frequency and the Phase Angle is adjusted on a potentiometer. To switch the potentiometer between the different parameters it just has to be pressed. From now on the Electronic AC -Source comes with Arbitrary Function. By simply switching via interface a change between sine wave and variable user curve is possible. The user memory can be set with up to 1024 dots for the user curve. Now very easy voltage spikes, drop outs, often in reality existing cut off crest voltage and much more can be simulated. The wave form is transferred via the USB or optional available RS232- or Ethernet Interface and then selected by sending a command or pressing a button. With this feature the electronic AC-Source can also be used as an arbitrary function generator with high power and high voltage of up to 425 V.
