Load Wiring

For applications using remote sensing, or for improved voltage regulation at the load, you must limit the voltage drop across each load line. We recommend that you use the larger load wiring to ensure a smaller voltage drop (1V maximum), although units will compensate for up to 5V drop in each line with the remote sense lines connected.

To minimize noise pickup or radiation, use the shortest possible length of shielded-twisted pair wiring for load lines. Connect the shield to the chassis via a rear panel mounting screw. Where shielding is not possible or is impractical, twisting the wires together offers some noise immunity. When using local sense connections, use the largest practical wire size to minimize the effects of load line impedance on the regulation of the supply.
