TEC 3-1221WI

TEC 3WI is a new series with the design purpose to improve the prevalent 3 Watt SIP-8 DC/DC converters in terms of cost, efficiency and performance. The latest technology and components effectuate a high efficiency for a low thermal loss. This enables an operating temperature range from -40°C up to +90°C. The converters are fully regulated over 0 - 100% load (no minimum load is required). The models are available with ultra-wide input ranges of 4.5-18, 9-36 and 18-75 VDC. The functional I/O-isolation system is designed to meet IEC/EN/UL 62368-1 (not certified) with a test voltage (60 s) of 1600 VDC.

Conformity
REACH Declaration

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

General REACH declaration

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.
