3-14 Basic Operation PAS SERIES
Because wires have resistance, voltage drop in wires becomes greater
as the wire becomes longer or the current becomes larger. This causes
the voltage applied at the load end to be smaller. The PAS series
power supplies have a sensing function that compensates for this volt-
age drop. Compensation of up to approximately 0.6 V is available for
a single line. If the voltage drop exceeds this level, wires having a
greater cross-sectional area should be used.

Withstand voltage of load cables
For load cables, use cables with a higher voltage
rating than the isola-
tion voltage of the unit. In particular, if the rated voltage of load
cables is lower than the isolation voltage of the power supply having a
rated output voltage of 40 V or more, electric shock may occur.
For details on the isolation voltage and the insulation, see "2.5
