Configuring Multiple Supplies For Split Supply Operation; Figure 3.4 Split Supply Operation Of Multiple Supplies - Xantrex XFR 6-200 Operating Manual

Local Operation
Using Multiple Supplies
Configuring
Split supply operation uses two power supplies to obtain two positive voltages with
a common ground, or to obtain a positive-negative supply.
Multiple
Supplies for
Two Positive Voltages To obtain two positive voltages, connect the negative

output terminals of both supplies together in a common connection. The positive
Operation
output terminals will provide the required voltages with respect to the common
connection. See Figure 3.4.

Figure 3.4 Split Supply Operation of Multiple Supplies

Positive-negative Supply
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. You can set the current limits independently. The maximum
current available in split supply operation is equal to the rated output of the supplies.
For example, 30 A for two 40 V, 30 A models. See Figure 3.5.

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