Converters

Le Cosinus has developed its own range of direct current power supplies, also known as AC/DC. As an electrical transformer manufacturer, we naturally positioned ourselves in the production of filtered rectified power supplies. Indeed, these particularly robust power supplies have as their main component a transformer, which we fully master and can adapt to your needs.

We are also recognised, particularly through our subsidiary OCME, for our expertise in more complex power supplies for especially demanding customers in the railway sector. For our customers, we manufacture a full range of safety power supplies. Most of these power supplies are regulated using ferroresonant transformers. 

All these safety power supplies for the railway sector undergo factory acceptance testing in our electrical test laboratory, thereby validating our expertise and our commitment to quality.
