7. APPLICATION
7-1. Use of Rear-Panel Terminals
Rear-panel output control
Fig. 5
The output and control terminals shown above are equipped on the rear panel. These
terminals may be used to perform remote sensing, remote control of output voltage and
output current, master/slave control operation with power supply connected in series or
paralled.
7-2. Remote Sensing
When the device is connected to a load, voltage drops due to contact resistance at the
output terminals and resistance of conductors. Remote sensing is performed to
compensate for the voltage drop.
1) Turn off power.
2) Remote the short bars(+)
－
(+S) and (-)
－
(-S).
3) Connect (+S) and (-S) to the load. Use a two-core shield cable for these sensing lines
and connect the shield line to (+) output.
4) (+) and (-) may be taken out from the output terminals on the panel or directly connected
to the load from the (+) and (-) terminals of the rear panel. Voltage drop of up to 1.2V per
way of the output line may be compensated for. If the voltage drop is lager than 0.5V, the
maximum rated voltage drops accordingly.
