-R (PBA50F / 75F / 100F / 150F)
¡
Option ”-R” is available for remote ON / OFF.
¡
When external power source is in the range of 4.5 - 12.5V, current
limit resistance R is not requierd. However, when external power
source exceeds 12.5V, current limit resistance R must be con-
nected.
To calculate the current limit resistance use following equation :
R[
W
]=
Where ;
Vcc=External Power Source
Ri=The internal resistance (780
W
)
¡
A wrong connection may damage the internal components of the
unit.
¡
Remote ON / OFF circuit (RC (+), RC (-) ) is isolated from input,
output and FG.

-N (PBA50F / 75F / 100F / 150F)
-
With case cover.
-
External size is changed and refer to External view.
-
Derating curve changes from the standard (Refer to 5.2).
-
Only -24 model is applying for the UL508 standard.
¿
-N1
-
-N1 means DIN rail attachment is attached to standard model.
-
Consult us external view in details.
-
-N1 becomes a type with case cover.
¿
-V (PBA50F / 75F / 100F / 150F)
-
A built-in potentiometer is lost, and connector which can be con-
nected with outside potentiometer is installed.
-
Consult us external view in details.
-
Please note that the output voltage becomes unstable when
CN5 is energized while opened.
¿
-K (PBA100F / 150F / only -3R3 / -5)
-
Remote sensing function can be used for option ”-K”.
-
Please note the correspondence model.
