OPTIONS
The PQ48050QNA20 comes in two versions that differ by
the sense of the logic used for the ON/OFF control signal.
The PQ48050QNA20P version uses positive logic; mean-
ing that the converter is on when the ON/OFF signal (Pin
2) is high. The PQ48050QNA20N version uses negative
logic; the converter is on when the ON/OFF signal is low.
Logic input is TTL compatible with an internal pull up.
SAFETY
The PQ48050QNA20 series of converters are UL 1950
recognized (US & Canada) with basic insulation rating
and TUV certified to EN60950 requirements.
The converters also meet 72/23/EEC and 93/68/EEC
directives as well as 94V-0 flammability requirements for
board and plastic components.
An external input fuse must always be used to meet these
safety requirements.
