VOLTCRAFT HPS-11530 Mode D'emploi page 39

Set output voltage
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
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 VDC). As of this voltage, you may only use insulated accessories.
Avoid the use of non-insulated metallic cables and contacts.
A ll 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.
E nsure a sufficient 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.
At the front sockets (9 and 10), only a current of max. 5 A can be tapped. An automated current
limitation is integrated
The screw sockets on the back are indicated for full nominal current.
From an output current of 20 A, the screw clamp function of the rear sockets is recommended to
avoid overheating of the plug sockets.
Remove any connected consumers from the output.
Switch on the power unit at the power switch (1). The operating display (2/3) lights up and the current and voltage
display appears on the display.
Set the parameters according to your specifications as described in the chapter "Start-Up".
Check once more that the correct output voltage is set.
