Introducing The

powerPerfector iQ


Designed to maximise security and cost savings

powerPerfector technology has evolved after a four-year research and development programme.

The powerPerfector iQ is the fastest, most accurate and precise control technology on the market. Standard optimisers can now be future proofed with the addition of the most precise electronic controller invented.

The powerPerfector iQ is now available for retrofitting onto your existing optimiser or as a brand new installation. The upgrades can take as little as two hours to install.

The retrofit can give you enhanced site security, reduced maintenance, up to 30% higher savings and substantially reduced capital replacement costs.


Why choose Responsive Power Optimisation™?

Recent studies have shown that power quality is diminishing resulting in reduced performance and increased wear of site electrical equipment; the powerPerfector iQ ensures that:

  • Existing powerPerfector savings are improved by up to 30%
  • Voltage instability and fluctuations are eliminated
  • Site equipment benefits from a highly stable voltage
  • Reacts to supply voltage changes within 250ms
  • Equipment efficiency is maximised due to active 3 phase balancing
  • The site is protected against harmful voltage dips, sags, intervals and swells
  • Precise output voltage control is provided across the whole site
  • Wi-Fi remote monitoring and intelligent control

    • powerPerfector

      The powerPerfector optimiser alters the incoming supply voltage at a fixed ratio, and is suitable for most buildings. Optimisation settings are referenced from the logging of your building’s incoming voltage supply in order to maximise your savings.

    • powerPerfector Plus

      The powerPerfector Plus features dynamic Voltage Power Optimisation, in addition to the power quality improvements afforded by the standard unit. Suitable for electrical supplies with high volatility, the powerPerfector Plus will adapt automatically to changing voltage conditions to give an optimised output to maximise savings.

    • Build Quality

      Attention to detail, unique design and build quality mean that hand wound powerPerfector units achieve a peak efficiency of 99.94%.

    • Engineering Excellence

      Installing any technology on the mains incoming supply to your building carries a risk. Our wealth of experience gained over the years has seen us develop industry-leading processes to mitigate risk for clients.
