Load Wire
Limitations of the sensing function
All wires have resistance. The voltage drop in wires becomes
greater as the wire becomes longer or the current becomes larger.
This results in the voltage applied at the load end to be smaller.
The PWR has a sensing function that compensates for this voltage
drop up to approximately 0.6 V for a single line. If the voltage drop
exceeds this level, wires having a greater sectional area should be
used.
