c) Energize power supply and adjust its output voltage to +24 VDC. Adjust Potentiometer to the desired
setting (between 12 VDC and 14 VDC) and observe converter voltage output reading on DVM
d) Turn off power supply.
3.2) Current Limit Adjustment
a) Hook up the unit to be adjusted as shown in Figure #5. Apply a load set to the desired current draw at
the limit point:

b) Turn the current limit pot completely clockwise. Turn on the power supply and note that the load is
drawing current and note the voltage on the DVM.
c) Turn C limit pot slowly counter clockwise while observing the DVM reading. When the voltage drops
by 100 mV while the pot is being turned, that designates that the current limit point has been reached.
d) Adjustment is complete. Turn off the power supply.
