3.4 External Programming

XR Series supplies allow voltage, current, voltage trip, and current trip to be programmed from a

remote location. Programming can be accomplished either by resistive, voltage, or current

programming circuits.

Figure 3.13 illustrates the three alternatives for programming the voltage set point. The method

applies equally to programming set point current, over voltage trip, and over current trip.
