TSR 3-1250A
The TSR 3 models are non isolated step down switching regulators. Since production May 2013 they can also be operated with negative output voltage.
They come in a very compact open frame package of 15.5 x 9.4 x 6.2mm. The high efficiency of up to 95% admits a full load operation up to 50°C and up to 85°C with 50% current reduction. A low standby current, a very wider input range and no requirement for heatsink give these switching regulators a significant advantage over linear regulators.
Togther with a remote On/Off input and protection against short circuit the TSR 3 Series models are ideal point of load regulators for high reliable and energy critical 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.
