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 always minimize the loop area or physical space between the + and - output
leads from the power supply 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.
Remote Sense Connections
Remote sensing improves the voltage regulation at the load by monitoring the voltage there instead of
at the output terminals. This allows the power supply to automatically compensate for the voltage
drop in the load leads. Remote sensing is especially useful for CV operation with load impedances that
vary or have significant lead resistance. It has no effect during CC operation. Because sensing is
independent of other power supply functions, remote sensing can be used regardless of how the
power supply is programmed.
Connect the unit for remote sensing as follows:
