Taking measures against noise
When connecting wires that have the same heat-resistant temperature, more current
can flow by separating the wires to make heat radiation as great as possible.
However, installing the + (pos.) and - (neg.) output wires of the load cable side by
side or bundling them together is more effective against unwanted noise. The
Kikusui-recommended currents shown in Table 3-1 are allowable current values
that have been reduced in consideration of the potential bundling of load cables. Use
these values as a guideline when connecting load cables.
■
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 PAT 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.
