  • Stand alone all-in-one down converter for remote feeding applications
  • Compliant with EN60950-21 RFT-C
  • Up to 300W output power
  • Fan cooled
  • Fully Isolated
  • Fed by up to 24 current limited high DC voltage lines (350V)
  • Embeded monitoring


This compact 300W remote energy solution provides high availability of power to remote sites in the local loop of the newest networks. The remote feeding solution operates on existing copper networks. It does not require any site safety approvals or input stage as it is not connected to the mains: it can be quickly and very cost effectively installed, enabling operators to promptly offer new services in remote areas. This solution takes advantage of the battery energy back-up power provided centrally. In this way high availability is provided at the remote site without increasing the number of remote battery locations and the exponential costs associated with their maintenance.
The module is designed to be mounted directly on a wall, a plate Snap-in connectors allow quick connection to the load and to the feeding pairs.
The remote feeding solution of Alpha Innovations is very safe. On the top of standard EN60950-1, it is also designed in combination with a central up converter compliant with the IEC/EN60950-21 safety standard. In addition, any circuit failure will shut down the source of power, eliminating any risk of electrical shock.
