Voltage Drops

The load wires must also be large enough to avoid excessive voltage drops due to the impedance of the wires. In general, if the wires are heavy enough to carry the maximum short circuit current without overheating, excessive voltage drops will not be a problem. The voltage drops across the load wires should be limited to less than two volts. Refer to Table 3-2 to calculate the voltage drop for some commonly used AWG copper wire.

Multiple Load Connections

When the unit is in local sensing mode and you are connecting multiple loads to the output, connect each load to the output terminals using separate load leads. This minimizes mutual coupling effects and takes full advantage of the dc source's low output impedance. Each pair of wires should be as short as possible and twisted or bundled to reduce lead inductance and noise pickup.

If cabling considerations require the use of distribution terminals that are located remotely from the dc source, connect the dc source’s output terminals to the remote distribution terminals by a pair of twisted or bundled wires. 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, sense directly at the critical load.
