The Energy Saving Transformer (EST) is a tapped auto-transformer which reduces voltage by up to 12%. This proportional reduction provides an effective way of prolonging the life of electrical equipment, reducing costs and cutting carbon emissions for sites with a reasonably stable mains supply.
At full load the EST Voltage Optimisation delivers efficiency of more than 99.5%. Many types of electrical equipment work perfectly well on a lower voltage than the standard mains supply, and indeed the performance of some equipment is actually optimised when the voltage is reduced. The EST can realise energy savings of up to 20% and help organisations meet their Carbon Reduction Commitments.
Is a voltage optimisation transformer that helps organisations make some of the biggest financial savings possible on their energy bills by reducing the mains voltage used to power electrical equipment. The Energy Saving Transformer(EST), a tapped auto-transformer, reduces voltage by up to 12%. The EST reduces input voltage by a fixed amount, making it ideal for sites with a reasonably stable voltage supply. This proportional reduction helps prolong the life of electrical equipment while reducing carbon emissions
Each kWh of electrical energy saved is equivalent to 0.537kg of CO2. With organisations facing a steady increase in electricity prices, the EST ensures a reduction on supply voltage while helping organisations reduce costs and meet their Carbon Reduction Commitments.
Many types of electrical equipment work perfectly well on a voltage lower than the standard mains supply. This is particularly true for equipment designed to operate on 380V or 400V three phase supplies where the supply is 415V, and for equipment designed for 230V or 220V single phase supplies where the supply is 240V. The EST provides a maximum output current of up to 3, 000 amps per phase to reduce voltage by between 3% and 12%.
Many types of electrical equipment work perfectly well on a voltage lower than the standard mains supply. This is particularly true for equipment designed to operate on 380V or 400V three phase supplies where the supply is 415V. The actual power supply is higher than necessary the equipment will consume more power than needed and in many cases, equipment life is reduced, effectively increasing the cost of ownership.
