Parallel Connections
Equipment Damage Only connect power supplies that have identical voltage and
current ratings in parallel. Keysight Models N678xA SMU may be paralleled, but
ONLY when operated in Current Priority mode. Voltage Priority operation is not
allowed.
Connecting power supplies in parallel provides a greater current capability than can be obtained from
a single unit.
The following figures show how to connect two outputs in parallel. The figure on the left illustrates
local sensing. If voltage drop in the load leads is a concern, the figure on the right shows how to
connect the sense leads directly at the load. Note that in both cases, the remote sense terminals
must be connected.
The following figure shows the connections for 50A power modules.
