Options
These options are usually ordered along with the device, as they are permanently built in or preconfigured during
the manufacturing process.
POWER RACKS
19“ rack
Racks in various configurations up to 42U as parallel systems are available, or mixed
with electronic load devices to create test systems. Further information in our product
catalogue, on our website or upon request

Water cooling
Replaces the standard cooling blocks of the internal power stages by three interconnected,
water cooled blocks with two taps led out for supply. This options helps to avoid heating
up the environment due to exhausted heat caused by a certain power dissipation when
the device or a cabinet full of units runs as source.
As a side effect, this type of cooling also reduces audible noise.

The control panel (HMI, standard models)
The HMI (

a USB port.
1.9.6.1
Touchscreen display
The graphic touchscreen display is divided into a number of areas. The complete display is touch sensitive and
can be operated by finger or stylus to control the equipment.
In normal operation the left hand side is used to show actual values and set values and the right hand side is used
to display status information:
Actual voltage display
Voltage set value input
Additional status
Status area
Actual current display
Current set value input
Touch area for
rotary knob assignment
DC terminal status
Actual power display
Power set value input
Indicator source/sink mode
Actual resistance display
Resistance set value input
Touch areas for menu
access
Quick menu
Touch areas may be enabled or disabled:
Black text = Enabled
Grey text = Touch area tempo-
rarily disabled
This applies to all touch areas. Some can additionally show a small padlock sign, indicating that
the feature is permanently locked, usually due to a specific setting.
•
Actual / set values area (left hand side)
In normal operation the actual values (large numbers) and set values (small numbers) for voltage, current, power
and resistance on the DC terminal are displayed. For the two operation modes, sink (displayed as
EL
) and source
(displayed as
PS
), there are two separate set values each for current, power and resistance. The two resistance
set values are only displayed while resistance mode is active, while an actual resistance is only displayed during
sink mode operation.
The actual values of current and power can be negative (signed) or positive (unsigned). A negative value belongs
to sink mode and indicates that the device is working as electronic load.
When the DC terminal is switched on the actual regulation mode is displayed as
CV, CC, CP
or
CR
,
next to the
corresponding actual value, as shown in the figure above.
The set values can be adjusted with the rotary knobs next to the display screen or can be entered directly via the
touchscreen. When adjusting with the knobs, pushing the knob will select the digit to be changed. Logically, the
values are increased by clockwise turning and decreased by anti-clockwise turning.
