SB Modules
The output voltage can be adjusted across the range shown in the datasheet
by using the potentiometer situated to the right of the signal connector.
Turning the potentiometer clockwise increases the output voltage.
The remote sense provides compensation for a maximum total load cable
drop of 0.5V for the output. The voltage at the output terminals must be within
the specified adjustment range. See the Remote Sense section in the
POWER SUPPLY OPERATION chapter for connection advice.
Signals
The Module Good signal is an isolated (200V from the output) opto-coupler transistor output. The maximum
current allowed through the transistor is 1mA. This signal provides an indication that the output is above 90% of
the output set voltage. The transistor is on when the output is “good”
Module inhibit is an isolated opto-coupler diode input. Passing a minimum of 1mA through the diode will inhibit
(turn off) the output of the module.
