THN 20-7223WIR

DC/DC Railway Converter • • Compact 1” x 1” metal package • Qualification for fire behavior according to EN 45545-2 • Wide 4:1 input voltage: 9-36, 18-75, 36-160 VDC • • • • • • THN 20WIR Series, 20 Watt EN 50155 and EN 61373 approval for railway applications UL 62368-1 IEC 62368-1 Operating temperature range -40 to +65 °C without derating The THN 20WIR series is a family of ruggedized 20 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 91% bration and thermal shock and come in a six-side shielded 1” x 1” metal package. The innovative design provides high efficiencies up to 91% and thus en3000 VDC I/O-isolation able an operating temperature range from -40 to +65°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 appli3-year product warranty cation. Built-in features like an internal EN 55032 class A filter, input undervoltage-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.
