5. Check that the voltage rating of the equipment does not exceed the

power supply’s rating.

Dual Power Supply Used in Independent Mode

Set the tracking switches 11 & 12 to the OUT position.

Constant Voltage Mode

1. Turn the master and slave output current adjustment control knobs (4

& 6) clockwise to the maximum position. Adjust the voltage adjustment
control knobs (3 & 5) counter clockwise to the minimum position.

2. Turn the power switch ON. Both CV LED’s should be lit.

3. Adjust the master and slave voltage adjustment control knobs (3 & 5)

to the desired voltage.

4. Connect the positive and negative output terminals to a load or similar

component.

Constant Current Mode

1. Turn the master and slave output voltage adjustment control knobs (3

& 5) clockwise to the maximum position. Adjust the current adjustment
control knobs (4 & 6) counter clockwise to the minimum position.

2. Turn the power switch ON. Both CC LED’s should be lit.

3. Connect the positive and negative output terminals to a load or similar

component.

4. Adjust the master and slave output current adjustment control knobs (4

& 6) to give the desired current.

Current Limit Protection Mode

(DC power supply: Output voltage less than 20V, or output current less than 2A)

1. Turn the master and slave output current adjustment control knobs (4 &

6) counter-clockwise to the minimum position. Turn the power switch ON.

2. Adjust the master and slave voltage adjustment control knobs (3 & 5)

to give the desired output voltage and then connect the output terminals
13 with 15 and 16 with 18 respectively.

3. Adjust the master and slave output current adjustment control knobs (4

& 6) to give the desired value or current limit. Remove the connection
between 13 & 15 and 16 & 18, and connect the load.
