PowerSave EST energy-saving transformer
Country: · Model: PowerSave EST
The PowerSave EST is an energy-saving transformer that steps the voltage down by a fixed amount of up to 12%. Typical energy savings reach 10%, and up to 20% on a stable supply. It is meant for sites with a steady but overvoltage mains.

Description
This is a fixed step-down transformer, so the reduction does not adapt to the mains and the supply itself has to be steady. Equipment then runs on a lower voltage, draws less energy and lasts longer. Efficiency exceeds 99.5% at full load, which keeps the transformer's own losses small. It is built in single-phase and three-phase versions and was designed and manufactured in the United Kingdom. A reduction of up to 12% should be checked against the tolerance of the connected loads, so the voltage at their input never falls below the limit they specify.
How to choose
The deciding parameters are the number of phases and the size of the reduction, up to 12%. Pick the single-phase or three-phase version to match the site supply. If the mains voltage drifts, a fixed reduction will not help and an adjustable device is needed, for example the Regavolt autotransformer with a smooth 0–100% or 0–115% output on a 3 kVA module. For portable work there is the Portavolt 715 with a 0–115% output. If a non-standard transformer is required, the power range covers 50 VA – 500 kVA to customer specification.

FAQ
By how much does the EST lower the voltage?
By up to 12%. A fixed reduction makes sense when the mains is stable but too high.
What energy savings does the PowerSave EST deliver?
Typically up to 10%, and up to 20% on a stable supply.
What is the efficiency of this transformer?
Over 99.5% at full load.
Does this transformer come in single-phase and three-phase versions?
Yes, both versions are built. The choice depends on the site supply.
Can the voltage reduction be adjusted?
No, the reduction is fixed at up to 12%. Smooth adjustment calls for an autotransformer such as the Regavolt.
