The TEP 40UIR is a series of high performance 40 Watt railway DC/DC converters with ultra wide 12:1 input voltage range featuring a compact ¼ brick (2.3”x1.45”x0.5”) metal package. The ultra wide input allows the converter to act as an all-in-one solution if different voltage ranges have to be covered in the same application, resolving the issue of having multiple different converters installed. An internal circuit implemented in these modules helps to extend the hold-up time with ease as it eliminates the need of expensive high voltage capacitors to cover the full input range. With only a 25V capacitor (independent of the input voltage) the whole input range can be covered effectively reducing cost, size and inrush current. All models are approved for railway applications according to EN 50155, EN 61373, EN 45545-2 and offer standard features such as high efficiency up to 91%, an operating temperature range of -40° to +85°C and an I/O-isolation voltage of 3’000 VAC. An adjustable under voltage lockout function, remote on/off and adjustable outputs round out the features and ensure that these converter modules fit in any application setup.

TRACOPOWER products do not generally fall under the REACH directive.
Our general REACH declaration is available via the following link:
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.
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.
