Railway DC/DC Converters

On this page we will share case studies our sister company Autronic have completed for railway and the successes of Cincons’ solutions for railway applications.

Autronic part of the Fortec Group, have developed and manufactured DC-DC converters since 1982, but their experience with customer-specific subassemblies and devices goes back as far as 1973.

Cincon also offer modified standard and custom power conversion products. Experienced in the design and manufacture of power supplies engineered to customer requirements. Cincon has a series of ultra-wide input range DC-DC converters to cover the various distributed voltages for the Railway applications.



Passenger information panel

Required: 150W in small package, with  high efficiency and wide voltage input (77 - 137)

Solution: ACR120 offers high efficiency in a small package with an ultra wide voltage range.

Offers temperature, shock, vibration and the railway-specific EMC criteria according to EN50121-3-2, as well as radiated emissions, surge, burst and ESD strict compliance with EN50155 is provided without additional components.

Train drivers door security lock 

Required: 20W, Input 52V (RIA12) & 110V (EN50155)

Output: 24V

Solution: EC7BW18-72S24 DC/DC converter

Ultra-wide input covers 52V &110V. The power solution was engineered with the customer so that a customised enclosure fitted the existing metalwork.

Highly reliable solutions for axle counters beside the tracks

Special solution for a customer to be used beside the rail tracks. The electrically isolated DC/DC converter supplies a safety application which energises the axle counters and accordingly controls rail traffic areas.

DC/DC converter modified to suit customers requirements

The original solutions with 24 VDC and 60 VDCin are replaced with a single DC/DC converter. The wide input range between 14.4 and 84 VDC helps to reduce the customer’s variety of models. Integrated is an active reverse-polarity protection, an active inrush current limitation as well as a hold up time of 10 ms.

A special current supply solution to be used in the black boxes of trains.

The isolated DC-DC converter with its cooling plate as part of the housing supplies the safety-critical applications to reliably record data during operation.  

DC/DC converter modified to suit customers requirements

The DC/DC converter was developed during product updating and for overseas use. The plug-and-play solution was based on the requirement that there is a possibility to upgrade already existing units. The ultrawide input range between 14.4 and 154 VDC can be used for all known nominal input voltages according to EN 50155. This facilitates a later qualification of the customer’s own component and reduces the storage costs.
