CONNECTING MULTIPLE LOADS
Proper connection of distributed loads is an important aspect of power supply use. Two common methods of
connection are the parallel power distribution method and the radical power distribution method.
PARALLEL POWER DISTRIBUTION
This distribution method involves connecting leads from the power supply to one load, from that load to the
next load, and so on for each load in the system. This method results in the voltage at each load depending on
the current drawn by the other loads and allows DC ground loops to develop. Except for low current
application, we do not recommend using this method.
RADIAL POWER DISTRIBUTION METHOD
To connect distributed loads, we recommend that you use radial power distribution. With this method, you
connect power to each load individually from a single pair of terminals designated as the positive and
negative distribution terminals. These terminals may be the power supply output terminals, the terminals of
one of the loads, or a distinct set of terminals especially established for distribution use. Connect the sense
leads to these to these terminals to compensate for losses and minimize the effect of one load upon another.
