OPERATING INSTRUCTIONS
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
Read current limit
Value from meter
Midrange
Adjust to
desired
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.
