New switch-mode stabilisers Traco TSRN-1 for positive and negative output

Novelty from Traco Power – switch-mode regulator TSRN-1, as a direct replacement for linear stabilisers 78xx, offers a few improvements in comparison to the recent type TSR-1.
This is an archive article published 09/13/2011. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

TSR-1 series already found many supporters, thanks to its features, like ability to directly replace linear stabilisers, high efficiency and a functionality even without input and output capacitors. Novelty TSRN-1, with improved features, spreads possibilities of usage of these regulators (DC/DC modules).

Similarly like TSR-1, offers TSRN-1 a direct compatibility (pin to pin) with 78xx stabilisers, contains filter capacitors, doesn´t require heatsink, has a shortcut protection and many other positive properties. Novelty is, that in comparison to type TSR-1, it offers a full load operation up to +70°C, and a derated operation up to +85°C, and moreover it contains a thermal protection, thus providing a higher protection to powered devices in case of unpredicted overheating of a device. For some applications, it can be an advantage, that TSRN-1 has also a wider input voltage range – up to 42V.

TSRN-1 is able to create negative supply thanks to a switch mode principle, thus without a necessity of another transformer winding, you have available negative power supply without extra costs.

SMD version TSRN-1 SM offers a possibility to adjust output voltage and it has a 1 extra pin for remote control (on/off) for decreasing of power consumption. TSRN-1 SM series is available in 6 versions, with a wide range of output voltage adjustment. Required output voltage is obtainable with more types, it is only necessary to choose, which one is the most suitable for your application, mainly depending on the input voltage.

On the 20-th anniversary occasion of SOS electronic brands, we offer to you a possibility to gain free samples of TSRN-1 SM.
