THN 20-3612UIR

THN 20-3612UIR is a THN 20UIR series DC/DC railway converter with an ultra-wide 12:1 input voltage range and a power output of 20W. It comes in a compact, fully encapsulated 1”x1” housing for highest reliability. The default variant features a pre-mounted heatsink for convection cooling up to +70°C without derating. Due to its dedicated holdup capacitor connection, it meets extended holdup-time requirements without the need for bulky input capacitors. It is EN 50155 certified for rolling stock applications, EN 61373 certified for resistance against mechanical shock and vibration and EN 45545-2 certified for fire behavior. It is also comes with IEC/EN/UL 62368-1 safety approvals for use in a wide range of demanding industrial applications. Device features protection against short-circuit (SCP), overvoltage (OVP) and overtemperature (OTP).
