The behavior of the unit output current, output voltage and the voltage rails
considering this example situation is shown in
Figure 24
(please note that a point-by-
point 0.1-Hz current sine wave is fed to the power supply):

voltage rails behavior for a low-value resistive load
where the
BLUE
line is the output current, the
RED
one the output voltage and the
GREEN
ones the rail voltages values.
Example 2.
Consider now running the automatic load procedure by sending an
‘MTUNE\r’ command to the power supply connected to a magnet load and that the
R
EST
value computed from this procedure is found to be 11.23Ω. In normal operation,
the LiAM power supply recognizes that the maximum required output voltage for this
load is equal to:
|
where “5A” is the maximum output current rating for the power supply.
In this case the LiAM power unit automatically recognized the “output”
voltage needs when setting a new current value and uses an hysteresis threshold in
order not to have several voltage rail commutations.
The behavior of the unit output current, output voltage and the voltage rails
considering this example situation is shown in
