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.
