Advanced Operation DLM-E 3kW & 4kW Series Power Supplies
CAUTION!
Remote sensing must not be used during series operation.
CAUTION!
The remote programming input is internally referenced to the supply's
negative output. Do not connect any remote programming input lines on the
J3 connector to the supply's positive output.

4.7.2 Configuring Multiple Supplies for 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.
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 4–18.
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 4–19.
