Parallel Connections
CAUTION
Only outputs that have equivalent voltage and current ratings can be connected
in parallel.
Connecting outputs in parallel provides a greater current capability
than can be obtained from a single output. Only parallel outputs that
have equivalent voltage and current capability.
As an example, the figure on the left shows how to connect two
outputs in parallel to a single load with local sensing.. If it is
necessary to remote voltage sense at the load, parallel the sense leads
of output 1 with the sense leads of output 2 and connect to the load
as shown in the figure in the right.
Setting the Outputs
Program both outputs to the desired output voltage. Then program
the current limit point of each output. The current limit point of the
paralleled outputs will be the sum of both individual current limit
points. The output current of the parallel combination will be the
algebraic sum of the individual current readbacks.
NOTE
The operating mode of each paralleled output channel is determined by the
channel’s programmed settings, operating point, and load condition. Because
these conditions may change during parallel operation, the status annunciators
on the front panel will reflect these changes. This is normal. Momentary status
changes are also normal.
