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 55022 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.
