DLM-E 3kW & 4kW Series Power Supplies Advanced Operation
Programming Output Current Limit with a 0–5k Ohm Resistance
1. Set S1-2, the rear panel DIP Switch, UP, in the open position for 0–5k ohm programming
range.
2. Connect pins 10 (current programming input/positive) and 22 (1mA current source for
current control) to the counter–clockwise end of the potentiometer and connect the tap
and clockwise end of the potentiometer to pin 12 (return). Adjusting the resistance from
zero to maximum will vary the output voltage from 0 to 100% of the model rating. Adjust
the programming signal to zero.
3. Turn the power supply ON.
4. Set the front panel LOCAL/REMOTE switch to the REMOTE position and adjust the
external programming resistance. By pressing the V&I PREVIEW button and observing
the front panel ammeter reading, the external control can be adjusted to the desired
setting.
