Providing Power and Communications

To accompany the BRAUMS Variable Message Sign product, we have developed a number of Roadside Cabinets depending on site requirements and wants and/or needs of the client. The Roadside Cabinets not only provide VMS power and communications interfaces to field personnel, but also for house optional battery back-up for the VMS Controller Module, external communications hardware, and the entire sign itself.

Roadside Cabinet installation


Standard facilities:

  • Power connection between the VMS and the energy supply
  • Communication interfacing hardware (Serial, Ethernet, Fibre, Cellular)
  • 4-Way Facility Switch
  • Uninterruptible Power Supply (UPS) and batteries for the VMS Controller Module and communications hardware


Optional facilities:

  • UPS and batteries for the whole sign (made possible due to the extremely low power consumption of the BRAUMS VMS)
  • Cabinet lighting
  • Solar equipment such as solar charge controller, inverter and gel batteries
