Dynamic arbitrary signals up to 1kHz defines this class of instruments as the superior class. Besides this improvement a clear miniaturization is involved due to the SMD technology. This miniaturization allows the integration of power packs up to a size of approx.300 W in the control center. Power packs can also be inte- grated in more compact casings. Decisive for elneos five is the packing density. This has been made possible by the SMD technology and the fully automatic calibrating function where the internal winding changeovers are controlled fully auto- matically by means of firmware. An additional new highlight is the integrated square-wave generator up to 250 Hz in load. elneos® five | 41 Precision regulating power supply unit incl. square-wave generator Ref. No. EL5.32 til Ref. No. EL5.61 (0-30V/0-2A til 0-60V/0-10A, see p.58) The regulating power supply units are a comprehen- sive device family with different voltages and currents. elneos five offers variable DC power supplies inclusive a universal measuring device of high precision. An essential feature is the development of a control card which can be used for all models. This control card is equipped with respective cooling elements and power transistors and is completed in different ways depen- ding on the model. Likewise each device is equipped with a transformer of different strength. Technical data and features of standard equipment Visualisation of the ramp functions Freely programmable ramps in tabular form. After starting the ramp, the voltage and the flow of the current are automatically visualized in a X-Y chart. Ramp input voltage and current: 1) Voltage ramps with current limitation 2) Current ramps with voltage limitation Preset function (output OFF/ON) Function for switching off and on the output. When the output is deactivated, the maximal current can be changed. Only when connecting the output the new maximal current value is activated. There is no need any more to isolate the circuit manually from the power pack. Read-out of all device conditions All device conditions can be read out by means of the interfaces. The conditions are directly displayed in the control software highlink Power. This scanning possibility can also be used in a sensible way for test systems. Source of constant voltage and constant current Automatic change of the operating modes CV and CC–On the one hand elneos five is a voltage source and on the other hand a current source. These characteristics allow to generate voltage ramps as well as current ramps.
