Description
The BBS4N48P12A series are sixteenth-brick DC/DC converters that provide high efficiency single output. It can operate from
36V to 75V input and 12V/4A output. The output can be trimmed from -20% to +10% of nominal output voltage. The remote
control options are negative logic. The converter turns on when the REM pins are at logic low and turns off when they are at
logic high or left open. The output voltage trim options are positive. The output voltage will increase when the TRIM pins are
connected to “+S” and decrease when connected to “-S”.
