The HeavyPower and EasyPower Connectors are part of the Smiths Interconnect's Transformer range, a comprehensive series of high density, high power, heavy duty, 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 connectors are suitable for any applications requiring the transmission of very high currents such as power distribution, intercoaches and bogies.

The HeavyPower Series is available in 1 to 4 pole versions, supporting up to 300A per pole and a voltage rating of 3600V. The HeavyPower connector is offered with straight termination, that allows for the easy mounting on the roof or under the car's floor or with right angle termination to facilitate the mounting between two cars. As a variant, the HeavyPower Y Series is also proposed as a branch connector acting as a junction box.

The EasyPower Series is available in 1 to 4 pole versions, supporting up to 500A 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.
