6.2.6. Connection to the Load
In parallel operation, power supplies can be connected in local or remote sensing. Refer
to Fig. 6-4 and 6-5 for typical connections of parallel power supplies. The figures show
connection of two units, however the same connection method applies up to 4 units.
Figure 6-4 Parallel Connection with Local Sensing
With local sensing it is important to minimize the wire length and resistance. Also the
positive and negative wire resistance should be as close as possible to each other to
achieve current balance between power supplies
