age when the unit is in voltage mode, or voltage limit when the unit is in current mode. Figure 3-
16 is a similar diagrams for programming either output current when the unit is in current mode,
or current limit when the unit is in voltage mode
CAUTION
Observe the following to avoid damage to the power supply. The external voltage source
output must be isolated from ground (floating output), or be powered from an a-c source that is
isolated from ground to avoid short-circuiting the internal sensing resistor.
The external voltage source is applied to the input of the uncommitted amplifier which is config-
ured as a noninverting amplifier having a gain of 10.
