OPERATING INSTRUCTIONS___________________________________________________________________________
8. If the load current exceeds the preset current limit, the
CONSTANT CURRENT 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 VOLTAGE control away from zero sufficiently
for the Constant Current indicator to light.
4. Adjust the CURRENT control for the desired current limit.
Read the current value on the mA meter.
5. The current limit (overload protection) has now been
preset. Do not change the CURRENT control setting after
this step.
6. Remove the short between the (+) and (-) terminals and
hook up for constant voltage operation.
Typical Constant Current Operation
1. Before connecting the device to be powered to the power
supply, determine the maximum safe voltage to be applied,
Figure 4. Typical constant voltage operation
set the A/B Meter s election switch to the A (up) position, and
set the VOLTAGE control to obtain that voltage reading on the
Volt meter.
2. Determine the desired constant current value.
3. Set the CURRENT control to minimum (fully
counterclockwise).
4. Turn off the power supply and connect it to the device to
be powered.
5. Turn on the power supply. The CONSTANT CURRENT
indicator should light.
6. The current can be read directly on the mA meter.
