DC/DC Railway Converter THN 10WIR Series, 10 Watt Compact 1 x 1 metal package EN 50155 and EN 61373 approval for railway applications Qualification for fire behavior according to EN 45545-2 Wide 4:1 input voltage: 9-36, 18-75, UL 62368-1 IEC 62368-1 36-160 VDC The THN 10WIR series is a family of ruggedized 10 Watt DC/DC converters for Operating temperature range -40 to highest reliability in harsh environments. The converters have a wide 4:1 input +80 C without derating range and increased resistance against electromagnetic interference, shock/vi- High efficiency up to 90% bration and thermal shock and come in a six-side shielded 1 x 1 metal pack- age. The innovative design provides high efficiencies up to 90% and thus en- 3000 VDC I/O-isolation able an operating temperature range from -40 to +80C 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 appli- 3-year product warranty cation. Built-in features like an internal EN 55032 class A filter, input un- der-voltage-lockout, short circuit protection, remote On/Off and output voltage trim make this series suitable for almost any application demands and thus fa- cilitate the design-in process.
