EasyPower Transformer Series
  • High density modular solution
  • High power, up to 700A
  • Straight and shunt termination styles
  • Reliable Hyperboloid and High Power Contact technologies
  • Cable section size from 25mm² to 240mm²


The EasyPower Series is part of the Transformer range, a comprehensive series of high density, modular connectors for all on-board power applications within the rail market.

The Transformer’s modularity enables customers to design their own solution by supplying the elementary components of the whole connector. It employs a unique do-it-yourself system based on the building block principle. The connector is suitable for any applications requiring the transmission of very high currents such as power distribution, intercoaches and bogies.


The EasyPower Series is available in 1 to 4 pole versions, supporting up to 700A per pole and a voltage rating of 3600V. The EasyPower connectors can be supplied in a straight version, that allows for the easy mounting on the roof or under the car’s floor. A straight version with a shunt is also available to facilitate mounting between two cars.

The connector uses the Smiths Interconnect's High Power Contact (HPC) technology in aluminum or copper that allows for more contact points to reduce overheating and to achieve low mating force during the connection. In addition, three contact sizes only are covering the cross section cables from 25mm² to 240mm², with consequent reduction of supply chain and cabling costs.


The EasyPower Series range is compliant with the main railway standards: NF F 61-030, EN 50647 and dEN 60373. The connectors also conform to EN 45545 fire and smoke standards and are made of plastic materials following NF F 101/102.
