DC/DC Railway Converter THN 30WIR Series, 30 Watt Encapsulated in 1x1 metal package EN 50155 and EN 61373 certified Wide 4:1 input voltage range: 9-36, 18-75, 36-160 VDC -40C up to +65C without derating Up to 91% efficiency UL 62368-1 IEC 62368-1 Up to 3000 VDC I/O-isolation The THN 30WIR is a series of DC/DC converters designed for highest reliability in harsh environments. With an output power of 30 Watts, this series expands EN 45545-2 fire behavior our portfolio of EN 50155 railway certified wide input voltage range 1x1 Remote on/off and trim function DC/DC converters. The THN 30WIR is shielded by a metal enclosure on all six sides for lowest susceptibility to electromagnetic interference. Its full encapsu- Undervoltage lockout (UVLO), lation guarantees highest resistance to thermal shocks as well as mechanical short-circuit protection (SCP), shocks and vibration. Thanks to its power conversion efficiency of up to 91%, overvoltage protection (OVP) and the THN 30WIR can operate at ambient temperatures between -40C and overtemperature protection (OTP) +65C without derating and without the need for additional cooling (depending 3-year product warranty on the model). The THN 30WIR is EN 61373 certified for mechanical shock and vibration and EN 45545-2 certified for fire behavior. It comes with IEC/- EN/UL 62368-1 safety approvals.
