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.


The Netformer is an isolation transformer that cancels the harmonic currents generated by the loads and supply single phase output to the rectifiers.

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.
