According to Railway Standard EN 50155 and 50121-3-2

Autronic present their series ACR350 with an output power of 350 watts.

Output power up to 350 Watt

This DC/DC converter for chassis mounting is shock and vibration resistant (EN61373) and has an extended temperature range between –40 °C and +85 °C.

This makes it suitable for rough and powerful application in industry, railway and transportation systems.

Both versions of the ACR350 are available with a very wide input from 14,4 V to 67,2V and 43 V to 154 V according EN50155 (nom. 24 V to 48 V and 72 V to 110V) and have an output voltage of 24 V.

The active clamping topology helps to meet the EMC requirements: The converter reach conducted emission Class B and radiated emission according to EN 55011 Class A and complies with the railway specific criteria of surge, burst and ESD without additional components. Standard feature are protection against over current, over temperature and reverse polarity as well as inrush current limiting, enable, thermal warning and power good. Easy installation because of the compact design (182 mm x 105 mm x 50 mm), a high efficiency of up to 94% and new cage clamp connectors.
