Netformer – 3 phase transformers

The patented NetFormer Transformer is an integral part of Netpowers DC UPS design eliminating all harmonics at PCC. A unique solution for large scale deployment.


  • Simple installation and operation

  • The power system is based on hot swappable rectifier modules

  • Power management system handles all control and monitoring in the system using TCP/IP based protocols

  • International standards compliant

  • System Functions

    Surge protection

    The isolation design gives added protection against power surges such as lighting strikes.

    Harmonic cancellation

    The unique patented design eliminates harmonics generated by the rectifiers making the data center fully compliant with grid code at PCC.

    One phase output

    The NetFormer is an integral part of the Netpower concept.
