Remote sensing pinout
By using these two “sensing” pins it is possible to sense the output voltage
directly on the load, thus recovering possible voltage drops on the output cables up to
1V.
It is strongly suggested to use twisted cables when using the
remote sensing
feature in order to minimize possible noise pick-up.
The FAST-PS-1K5 is shipped with a mating connector for the remote sensing
that short-circuits the +S and + pins and the –S and – pins respectively. This
configuration performs the remote sensing directly at the output connector of the
power unit. LS and –S pins disconnected will make the power supply sense
the output voltage directly at the output terminal connections. When using the remote
sensing feature leave pins #2 (
+
) and #3 (
–
) disconnected.
In order to perform remote sensing at different points – e.g. the load terminals
– it would be necessary to connect Pin #1 and Pin #4 as in
