Where no setting is made within 2 seconds, the display switches back to the current
current display.
5. Turn the control to the left or right to set the current limitation. After switching on, the ne settings
area (0.1 A) is always active. This is indicated by a slightly lighter digit. Press the rotary control
slightly from the front. The decimal position (1.0 or 0.1) of the setting range changes each time you
press. Turning changes the value.
6. Settings can be made coarsely (whole numbers) or ne (by tenths).
7. Where the desired current value was set, the display switches back to normal display after 2 seconds.
If the preset current is reached in normal operation, the power unit switches to current limitation
mode and reduces the voltage value. This operation is signalled with the red status display
C.C. (1).
b) Set output voltage
The output voltage can be set at the control knob VOLTAGE (3) control. The coarse and ne control
is performed in the same way as for setting the current limitation.
With the large control range, it is possible that the voltage setting takes approx.
1- 2 seconds to switch from a high to a low voltage value.
In normal mode the device operates in constant voltage mode. This means that the power
unit emits a constant, preset output voltage. This operation is indicated with a green status
LED C.V. (1).
c) Connecting a load
When connecting a consumer, make sure that it is connected to the power unit when
switched off. The maximum current consumption of the device to be connected
must not exceed the capacity indicated in the technical specications.
For serial connection of the outputs with several power supplies, the resulting
voltages can be fatal on contact (> 75 V/DC). As of this voltage, you may only use
insulated accessories.
Avoid the use of non-insulated metallic cables and contacts. All these exposed
areas must be covered with suitable, ame-resistant insulation materials or by other
measures and be protected from direct contact and short circuits.
Ensure a sufcient cable diameter for the intended current.
The power unit has two outputs. These outputs always have the same output voltage. The difference,
however, is in the current carrying capacity.
