Split Supply
Operation
Split supply operation uses two power supplies to obtain two positive voltages with
a common ground, or to obtain a positive-negative supply.
Two Positive Voltages To obtain two positive voltages, connect the negative
output terminals of both supplies together in a common connection. The positive
output terminals will provide the required voltages with respect to the common
connection.

Positive-negative supply To obtain a positive-negative supply, connect the
negative output terminal of one supply to the positive terminal of the second supply.
The positive output terminal of the first supply now provides a positive voltage
relative to the common connection. The negative output terminal of the second
supply provides the negative voltage. The current limits can be set independently of
each other. The maximum current available in split operation is equal to the rated
output of the supplies.
