EVO

Enhanced Voltage Optimisation up to 2 MVA, reduce energy consumption by reducing the LV supply voltage.

    VO Calculator

    The EVO and control unit provides one of the simplest and most effective means to reduce energy consumption by reducing the LV supply voltage within your installation. In addition, it is also able to provide voltage control where the normal low voltage supply exhibits unacceptable variations using dynamic control.  This is achieved by using electronics which enable voltage reduction and boost.  With very low losses and very high reliability, voltage optimisation delivers energy consumption reduction in an efficient and reliable way. Any use of voltage optimisation technology should be supported by a thorough installation analysis (in order to ensure the correct application solution) using the highly recommended  IPMVP (International Performances Measurement & Verification Protocol)
