Ordering Examples
RP15-2405SFW/P = 24V 4:1 Input, 5V Output, Positive Logic CTRL pin fitted
RP15-4805DFW-HC = 48V 4:1Input, ±5V Output, No CTRL pin, Heat-sink fitted
Notes:
Note3: Standard part is without suffixes and CTRL pin isn’t fitted
add suffix “P” for CTRL function with positive logic (1=ON, 0=OFF)
add suffix “N” for CTRL function with negative logic (0=ON, 1=OFF)
Note4: add suffix -HC for premounted Heat-sink and clips
