The THN 15WIR series is a family of ruggedized 15 Watt DC/DC converters
for highest reliability in harsh environments. The converters have an increased
resistance against electromagnetic interference, shock/vibration and thermal
shock. The approvals according to standards EN 50155 and EN 61373 qualify
them for railway and transportation systems. The qualification for the fire be-
haviour of components according to EN 45545-2 and the safety approval ac-
cording IEC/EN 60950-1, UL60950-1 support a potential compliance test of
the application. Built-in EMI 55032 class A filter, input under-voltage-lockout,
short circuit protection, remote On/Off and output voltage trim are further fea-
tures which facilitate the design in.
