Operation
Setup Menu : Supply
Note
The operating current must be less than 0.1% of I
max
in order to
change the supply selection. If a change is attempted above this
current, the Model 420 will beep and ignore the keypress. Power
supply selection should also preferably be performed with the power
supply off for maximum safety.
The power supply settings define the V-I ranges for a specific
supply. For example, V-I diagrams are presented in Figure 3-3 for
the AMI 12100PS and AMI 4Q05100PS selections. The AMI
12100PS operates as a one-quadrant system without the addition of
an energy absorber. With the addition of an energy absorber, the
AMI 12100PS system can function as a two-quadrant supply. The
AMI 4Q05100PS power supply operates as a four-quadrant power
supply without the addition of an energy absorber.
The addition of an energy absorber to the system does not change
the capabilities of the power supply (or the values entered for the
supply). The addition of an energy absorber does, however, change
the system operating ranges per the example of Figure 3-3.

a. The Kepco supplies are limited to only 1/2 of the output voltage range since the
supplies are only designed to safely dissipate 1/2 of the rated power output.
b. The values shown for the Custom... option are defaults. The user should enter the
appropriate values within the respective submenus. Custom values, once entered,
are saved between power-ups.
