Multiple Supplies

Multiple Supplies
Power supplies of the SAME MODEL in this series may be operated with outputs in
series or parallel to obtain increased load voltage or current. Split supply operation
allows two positive or a positive and negative output to be obtained.
Note: If your application requires the use of isolated programming inputs, contact
the factory about the optional ISOL interface.
Series
Operation
Series operation is used to obtain a higher voltage single output supply using two or
more single units. Connect the negative terminal (-) of one supply to the positive
terminal (+) of the next supply. 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 rated output current of
a single supply in the string.
Note: The maximum allowable sum of the output voltages is 600V. This is limited
by the voltage rating of certain internal components.

CAUTION
!
All remote programming input and monitoring lines are internally referenced to the
supply's negative output. Do not reference remote programming or monitor lines to
the supply's positive output. J3 pin 6 (ground) is directly connected to the supply's
negative output. Do not connect this pin to the positive output or to the chassis.
CAUTION
!
Do not use remote sensing during series operation.
