THN 20UIR
The THN 20UIR is a series of high-performance DC/DC converters with an ultra-wide 12:1 input voltage range and a power output of 20 watt. The THN 20UIR 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. Thanks to its dedicated holdup capacitor connection, the THN 20UIR meets extended holdup-time requirements without the need for bulky input capacitors. The THN 20UIR 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. The THN 20UIR also comes with IEC/EN/UL 62368-1 safety approvals for use in a wide range of demanding industrial applications.

Conformity
REACH Declaration
TRACOPOWER products do not generally fall under the REACH directive.
Our general REACH declaration is available via the following link:
RoHS Compliance
TRACOPOWER completed successfully in July, 2006 the process of producing all power supply and dc/dc converter fully compliant to the European RoHS Directive (2002/95/EC). Excepted are those products which have been removed from the actual sales program (obsolete products).
The EU RoHS Directive and the China RoHS both denominate identical Substances and MCV’s (Maximum Concentration Values).
The current TRACO POWER RoHS declaration therefore satisfies the EU RoHS Directive as well as the China RoHS Regulation.
Cleaning Guideline
We generally do not recommend washing or cleaning electronic components. You should avoid it, if it is not absolutely necessary. Please refer to cleaning guide.
