Input fuse
A fuse for AC input. If the fuse is blown out, the input power is
shut down and the output is turned off. When replacing the
fuse, see page 66, 6.1 Replacing the Fuse.

Remote Sensing
The remote sensing function is used to reduce the influence of
voltage drops due to the load cable resistance and stabilize the
output voltage across the load. The remote sensing function of
this power supply can compensate up to approximately 0.6 V
for a single line.
To perform remote sensing, an electrolytic capacitor of several-
hundred
μ
F is required at the sensing point (load terminal).
・
The remote sensing function is not available on models
with rated output of 70 V or higher.
・
When the remote sensing function is not performed,
make sure that the setting is in off position.
Handling of SENSING terminals
Strip the wire insulation and insert the wire into the hole while
holding down part A of the terminal using a flat-blade screw-
driver or other similar means. See Fig. 4-2.
