Operation
Split supply operation uses two power supplies to obtain two positive voltages with
a common ground, or to obtain a positive-negative supply.
To obtain
two positive voltages
, connect the negative output terminals of both
supplies together. The positive output terminals will provide the required voltages
with respect to the common connection. See
Figure 3.25
. To obtain a
positive-negative supply
, connect the negative output terminal of one supply to the
positive output terminal of the second supply. The positive output terminal of the
first supply then provides a positive voltage relative to the common connection while
the negative output terminal of the second supply provides a negative voltage. The
current limits can be set independently. The maximum current available in split
supply operation is equal to the model-rated output of the supplies used. See
Figure 3.26
.

CAUTION
To prevent possible damage to the supply, do not connect the remote program return
line of the negative supply to the common connection.
