About the power supply

Attention! When grounding one of the output poles always

check if one of the poles of the load (eg. electronic load) is

also grounded. This could result in a short-circuit!

Attention! Notice the potential shift of the output poles

when using series connection! Grounding is hereby only

recommended at the pole with the lowest potential against

ground.

5.4 Terminal „Sense“ (Remote sense)

In order to compensate the voltage drop along the load leads

(max. 1V per lead), the power supply can „sense“ the voltage at

the load instead at the output. It will regulate the output voltage

so that the desired voltage is provided to the load.

The remote sense feature is wired with correct polarity to the

terminal Sense.

(+) Sense must only be connected to (+) at the load

application and (–) Sense must only be connected to

(–)! Else both systems can take damage.

For additional information also see section „10.1 Remote sen-

se“.

5.5 Interface card slot

The unit can be equipped with an optional interface card. The

slot to insert the card is located at the rear side. Further informa-

tion about the interface cards can be found in section „8. Digital

interfaces“.

6. Handling

6.1 The display

Figure 3 shows an overview of the graphical display. During

normal operation, the display shows the actual and set values of

voltage (upper left), current (upper right) and power (lower left).

In device setup mode, it display parameters and settings.

The power set value is only displayed at models from 1kW.

In case the optional „internal resistance control“ is unlocked, the

power set value might be replaced by the internal resistance set

value, depending on what is selected in the device setup.

6.2 Used symbols

In the following description the display and operating elements

are marked differently by symbols.

 = Displayed only, all elements which are only displayed

and which represent a state are marked with this symbol

= Parameter, changeable values, are marked with this

symbol and are emphasised

 = Menu items, selectable, lead to the next sublevel or to

the bottom level with parameters

Brackets {…} mark possible options or adjustment ranges for

parameters.
