Multiple Load Connections

If you are using local sensing and are connecting multiple loads to one output, connect each load to
the output terminals using separate connecting wires as shown in the following figure. This minimizes
mutual coupling effects and takes full advantage of the power supply's low output impedance. Keep
each pair of wires as short as possible and twist or bundle them to reduce lead inductance and noise
pickup. The goal is to minimize the loop area or physical space between the + and - output leads from
the bus bars to the load.
If load considerations require the use of distribution terminals that are located away from the power
supply, twist or bundle the wires from the output terminals to the remote distribution terminals.
Connect each load to the distribution terminals separately. Remote voltage sensing is recommended
under these circumstances. Sense either at the remote distribution terminals or, if one load is more
sensitive than the others, directly at the critical load.
