THR 3-4812WI

The THR 3WI is 3 Watt DC/DC converters series with reinforced isolation (3000 VAC). These regulated DC/DC converters come in either a DIP-24 package and also feature increased resistance against shock and vibration according to EN 61373. The THR 3WI offers an internal input filter to comply with EN 55032 class A. High efficiencies up to 85% allow safe operation from –40°C to +92°C (with derating). All models have a wide 4:1 input voltage range and precisely regulated, isolated output voltages. With the latest IT safety certifications (IEC/EN/UL 62368-1) the THR 3WI series is the perfect choice for many demanding applications in the industrial, transportation and instrumentation sectors.

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.
