Operating instructions

3.1

Mains input

The mains input connector is located on the rear of the unit. Before connecting to the mains supply the user

should verfy that the unit is set to the correct voltage for the country of use. The mains voltage is set by the

external mains voltage selector switch located on the rear of the unit.

3.2

Mains input fuse

The mains fuse is located on the rear of the unit. The correct fuse for each supply voltage is as follows :

Model

HV10001

HV20001

HV30001

3.3

Power on/off

The mains power to the unit is switched on and off using the POWER on/off pushbutton.

3.4

Voltage and current display

HV10001, HV20001 and HV30001 feature independent displays for both output voltage and output current.

3.5

Output voltage and output current

The output voltage is adjusted to the desired value using both the Coarse and Fine Voltage controls. The out-

put current level is adjusted to the desired value usng both the Coarse and Fine Current controls. If the output

current exceeds the set current value the power supply will limit the output current to the set value.

3.6

Caution

The HV series power supplies include short circuit protection, if a short circuit occurs the unit should be

switched off. The level of the current limit can be set by connecting a resistor to give an output current of 1A

or less.
