Using Multiple Supplies
Power supplies of the SAME MODEL in this series may be operated with outputs in
series or in parallel to obtain increased load voltage or increased current. Split supply
operation allows two positive or a positive and a negative output to be obtained.

Series
Operation
Series operation is used to obtain a higher voltage from a single output using two or
more supplies. Connect the negative (-) output terminal of one supply to the
positive (+) output terminal of the next supply. See
Figure 3.23 . The total voltage
available is the sum of the maximum voltages of each supply (add voltmeter
readings). The maximum allowable current for a series string of power supplies is
the model-rated output current of a single supply in the string.
Note: The maximum allowable sum of the output voltages is 600Vdc. This is limited
by the voltage rating of certain internal components.
!
CAUTION
Do not use remote sensing during series operation.
!
CAUTION
The remote programming input is internally referenced to the supply's negative
output. Do not connect remote programming input lines (J3 pins 9 and 10) to the
supply's positive output.
