Note A: Remark regarding UL testing: the secondary side Pin 7 BPS power the IC internal controller on the secondary side and functioned as a

constant current load. The pin is intended to accept a voltage in the 8-24 VDC range, which is shown on the spec, and drew 818 mW max at

the high end of the voltage range.
