Powerstar HV MAX provides a combined solution to two common problems, combining a super low-loss amorphous core HV/LV transformer with integrated variable voltage optimisation technology.

Powerstar HV MAX should not be compared to a standard low-low, energy efficient transformer.
Its is a combined solution that not only offers the benefits of a HV transformer but also additional savings and security through electronic voltage optimisation and stabilised voltage.
The Powerstar HV MAX system is ideal for sites with the following profile:
If Powerstar HV MAX does not fit your requirements then have a look at the LV range of voltage optimisation systems available with either Powerstar fixed voltage optimisation or Powerstar MAX variable voltage optimisation.
A HV/LV transformer is required to convert high voltage (HV) electricity supplied from the grid into low voltage electricity (LV) for safe use on site. Transformers are required to operate 24 hours a day, 365 days a year, during which time they will undergo constant losses which can be significant depending on the age and efficiency of the transformer used.
This loss is defined in two categories
Super-low loss amorphous transformers significantly reduce the losses experienced in both load and non-load states which provide savings on electricity consumption and lower carbon emissions. With electronic-variable voltage optimisation technology combined as part of Powerstar HV MAX, additional savings on the LV side are also delivered on top of reductions achieved through replacing the HV/LV transformer.

The Powerstar HV MAX is available in a range of sizes from 315kVA to 2,500kVA.
It allows for 11,000V/20,000V/22,000V/33,000V input with a regulated 433V nominal with electronically regulated 380V (or user defined) output.
Included with the Powerstar HV MAX system is the HMI (Human Machine Interface), and automatic voltage reduction bypass. Additional options include harmonic mitigation winding and manual switch bypass.
The Powerstar MAX systems are not off the shelf solutions and are engineered to suit the voltage characteristics of each site.
