By using the two “sensing” pins (S+ and S-, pins 4 and 1, respectively), it is
possible to sense the output voltage directly on the load, thus neglecting eventual
voltage drops on the output cables up to 0.5 V.
It is strongly recommended to use twisted cables when using the remote sensing feature
to limit the pick-up noise.
The FAST-Bi-1K5 is shipped with a mating connector for the remote sensing
that short-circuits the S+ and + pins and the S– and – pins, respectively (see Figure 15 ).
This configuration performs the remote sensing directly at the output connector of the
PS. When using the remote sensing feature, leave pins #2 (
+ ) and #3 (
–
) disconnected.
