THN 10WIR Series, 10 Watt
EN 50155 and EN 61373 approval for
railway applications
UL 62368-1 IEC 62368-1
The THN 10WIR series is a family of ruggedized 10 Watt DC/DC converters for
highest reliability in harsh environments. The converters have a wide 4:1 input
range and increased resistance against electromagnetic interference, shock/viHigh efficiency up to 90%
bration and thermal shock and come in a six-side shielded 1” x 1” metal package. The innovative design provides high efficiencies up to 90% and thus en3000 VDC I/O-isolation
able an operating temperature range from -40 to +80°C without derating. The
Protection against overload, overvoltage approvals according to standards EN 50155 and EN 61373 qualify them for
and short circuit
railway and transportation systems. Additional qualification for the fire behavior
of components according to EN 45545-2 and the safety approval according
Remote On/Off and Trim function
IEC/EN 62368-1, UL62368-1 support a potential compliance test of the application. Built-in features like an internal EN 55032 class A filter, input un3-year product warranty
der-voltage-lockout, short circuit protection, remote On/Off and output voltage
trim make this series suitable for almost any application demands and thus facilitate the design-in process.
