AC/DC Regulated Converters

Provide DC regulated power from AC source.

Features and benefits

Wide range of power converters to provide DC electrical power for aerospace networks. They can include simple or complex embedded monitoring, allowing operators to manage external components or equipment.

AC/DC converter

  • Regulated Converters

Used to create high quality DCV networks. They hold network voltage within ±1.5 % of rated voltage up to the rated current; then limit power on the output (up to the defined overload) and finally manage a short circuit current limitation.

These units present ratings between 200 A and 400 A for 28 VDC networks.

Other features include:

  • Embedded fan, removing the need for a blown air circuit on the aircraft
  • Monitoring and communication module, to manage part of the surrounding environment
  • Embedded firmware and/or software

Certification approvals for power converters

DO178 certified software (up to DAL B)
DO254 certified hardware (up to DAL B)


Used on commercial or military platforms in the following applications:

  • DC network generation for aircraft with AC generators
  • BCRU- Battery Control and Rectifier Unit for aircraft
  • DC power for applications needing different voltages to the one on the network

At Meggitt, we can provide you with a regulated converter that is specifically designed and tuned for your application. To discuss what you need in more detail, please contact us.
