AC/DC transformer rectifier units (TRU)

Convert main electrical network into the secondary network

Convert main electrical aircraft network (115 VAC, 3 phase) into the secondary electrical network (28 VDC)

Features and benefits

The units include the following functions:

  • Supply a 100 A operating current (free convection) and a 200 A operating current (air extraction flow = 24 g/s)
  • Unregulated configuration – without fan – for exceptional reliability
  • High level of protections and measurements
  • Very low output ripples voltage

Each design is unique to the application. To discuss what you need in more detail contact us

Applications

They are used throughout the aircraft electrical network in a wide range of applications.
