IFU Series

IFU units are a solution we propose to integrate some elementary train functions into a single product. We can in fact supply contactors, disconnectors, current sensors, and resistors assembled in the same structure. Our IFU units can be a combination of our own products and other components you can specify.

  • Ratings up to 4000 VDC/AC and up to 3000 A applications
  • Plug & Play approach
  • Equipped with a unique low-voltage connector
  • Easier for you to specify and integrate, while internal design is in our scope
  • Easier to install and maintain, with reduced mechanical and electrical interfaces
  • Compact solution guaranteed, based on our deep components knowledge
  • Easier to test: we perform routine tests for the entire IFU functions, considering all mutual interactions
  • Easier access to technical information in the documentation that we provide

IFU is a 100% customized product. On the same baseplate, it can implement at least two of the followings:

  • Line contactor
  • Pre-charge contactor
  • Pre-charge Resistor
  • Discharge contactor
  • Change-over switch for Output transformer configurator
  • Change-over switch for Auxiliary converter configuration
  • Current Transducer
