3.0 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
SM5020
SM3040
SM10010
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
SM5020, SM3040 and SM10010 feature independent displays for both output voltage and output current.
3.5 Output terminals
The SM3040 has two sets of output terminals. For output currents exceeding 20A both sets of terminals must
be connected in parallel.
3.6 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.
3.7 Caution
In the event of a short circuit at the output the current will limit at the value set by the current controls, how-
ever the unit should be turned off and the short circuit removed before continuing use.
