Figure 5. Setting Current Limit.

5. . Increase the

VOLTAGE

setting until the Voltage LED

display reads the desired value. The FINE control permits

easier setting to a specific value.

6. Note the load current on the Current LED display.

7. If the load current exceeds the preset current limit, the CV

indicator will go off and the CC indicator will light. In this

case, the power supply automatically switches to the

constant current mode, and further rotation of the

VOLTAGE control will not increase the output voltage.

SETTING CURRENT LIMIT

1. Determine the maximum safe current for the device to be

powered.

2. Temporarily short the (+) and (-) terminals of the power

supply together with a test lead.

3. Rotate the Coarse VOLTAGE control away from zero

sufficiently for the CC indicator to light.

4. Adjust the Coarse and Fine CURRENT control for the

desired current limit. Read the current value on the Current

LED display.

5. The current limit (overload protection) has now been preset.

Do not change the CURRENT controls settings after this

step.

6. Remove the short between the (+) and (-) terminals and hook

up for constant voltage operation.
