OPERATING INSTRUCTIONS
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.
