Set Output Voltage - VOLTCRAFT HPS-11530 Mode D'emploi

Set current limitation
1
Limiting the output current is a protection mechanism to protect the consumer or connection cables. Current limitation
can be pre-set at the output without any short circuit. The power unit then supplies the maximum current set.
1. Remove any connected consumers from the power unit.
2. Switch on the power unit at the power switch (1). The display (2 and 3) lights up, and after a short selftest, the
current and voltage displays appear.
3. Set the current limitation at the "CURRENT" control according to your application.
4. Turn the control and a current limitation value appears.
Where no setting is made within 3 seconds, the display switches back to the current display.
5. Turn the control to the left or right to set the current limitation. After switching on, the fine 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.
Settings can be made coarsely (whole numbers) or fine (by tenths).
Where the desired current value was set, the display switches back to normal display after 3 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." (5).

Set output voltage

2
The output voltage can be set at the "VOLTAGE" (7) control. The coarse and fine 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 display "CV" (4).
Connecting a load
3
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 specifications.
For serial connection of the outputs with several power supplies, the resulting voltages can be fatal on
contact (> 70 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, flame-resistant insulation materials or by other
measures and be protected from direct contact and short circuits.
Ensure a sufficient cable diameter for the intended current.
