Remote Sensing and Local Sensing
Remote sensing compensates the cable loss between PSH and load,
up to 0.5V. Use remote sensing whenever the load voltage has to
be accurate.
Local Sensing
(default)
VSET = VOUT

OUT > VLOAD

Sense
PSH Load
The sense terminal is internally connected to the
PSH output terminal. The delta between the
voltage setting level (V
SET) and the actual output
level (V
OUT) is compensated. The load terminal
voltage (V
LOAD) might become lower than the
output due to cable loss.

Setting
VSET
|VSET–VLOAD|
The sense terminal is connected to the load input
terminal. The delta between the voltage setting
level (V
SET) and the actual load voltage (VLOAD) is
compensated. The output voltage (V
OUT) might
become higher than the setting due to the
compensation.
