Figure 10: Series-Tracking Applications
Parallel Tracking
When the A/B OUTPUTS selector is set to PARALLEL TRACK-
ING, the + outputs of the A and B variable supplies are connected
and the – outputs of the A and B variable supplies are connected.
The resulting combination is a single supply capable of providing
0 V to 20 V and up to 1.2 A. Control is provided by the A VOLTAGE
and A CURRENT controls. The B VOLTAGE and B CURRENT
controls should be set fully clockwise. The parallel output may be
floating or ground referenced, but only one terminal (+ or –) may be
at ground reference. Those options are shown in Figure 11.
The 5 V fixed supply may be independently grounded or allowed to
float.
