Sense Lines
This feature is available only for the outputs Vo1, Vo2, Vo3,
and allows the compensation of voltage drops across the
connector contacts and if necessary, across the load lines.
To ensure correct operation, all sense lines S+ (Vo1SENSE,
Vo2SENSE, and Vo3SENSE) should be connected to the
respective power outputs. The common sense return S–
(SRTN) should be connected to RTN (pin 5 – 12).
The voltage difference between any sense line at its
respective power output pin (as measured on the
connector) should not exceed the following values.

Note: Open sense lines are admissible, but the output
voltage regulation will be poor.
Note: If the sense lines S+ and S– compensate for a
considerable voltage drop, the output loads shall be reduced
in order to respect the maximum output power.
