Connecting Supplies in Auto-Parallel

Auto-Parallel Wiring (Figure 4-4e).Figure 4-4e illustrates how power supplies can be connected in auto-parallel for increased current output. You can connect up to five supplies 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" supply and the + output terminal of the first "slave" supply 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 supplies. If remote sensing is required, connect the load to the remote sense terminals of the master supply, as shown by the dashed lines in Figure 4-4e.

Program only the master. Set slave output and OVP voltage slightly higher than the master to ensure that slave stays in CC mode
