Load Wiring
Length for
Operation
with Sense
Lines
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.
Noise and
Impedance
Effects
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.
