ACR120/Ks, small and powerful

 

Autronic presents their brand new DC/DC-converter ACR120/Ks for chassis mounting with a compact design and 150W power. The input range of 66 up to 154VDC is suitable for 110VDC input according to EN 50155.

With regard to temperature, shock, vibration and the railway-specific EMC criteria according to EN 50121-3-2, conducted and radiated emission acc. to EN 55011, immunity acc. to EN 61000-4-3 and the compliance with EN 50155 is provided without additional components. Further, the converter has an integrated hold-up time of 10 ms (class S2), which makes the compact converter (113 x 46 x 35mm) really unique. The efficiency of 93% allows to use the railway converter with full power without any derating according temperature class TX (-40…85°C). 

An integrated inrush current limitation, reverse polarity protection, protection against over voltage and over current will facilitate the design in of the power supply. The converter is designed for parallel use and in addition, the converter is open-circuit stable and continuously short-circuit proof.  The ACR120 is also compliant to EN45545-2 (R25; R24).


The new converter with an output of 24VDC is available now, other outputs on request.
