Connecting One Power supply To Multiple Loads
Figure 4-6 shows how to connect a single power supply to more than one load. When connecting multiple loads to the power supply with local sensing, connect each load to the output bus bars with separate connecting wires. This minimizes mutual coupling effects and takes full advantage of the unit’s low output impedance. Keep each pair of load wires as short as possible and twist or bundle them to reduce lead inductance and noise pickup.

Connecting Units in Auto-Parallel
Figure 4-7 illustrates how power supplies can be connected in auto-parallel for increased current output. You can connect up to five units of the same model.
Use load leads of a sufficient wire size so that the absolute voltage difference between the + output terminal of the "master" unit and the + output terminal of the first "slave" unit is kept under 2 V at rated current. This also applies to the voltage difference between the + output terminals of the first and second slave units. If remote sensing is required, connect the load to the remote sense terminals of the master unit, as shown by the dashed lines in Figure 4-7.
