Voltage Stabilisers

Enerdoor offers a wide range of voltage stabilisers from 230-400Vac and rated power from 1-4000kVA. The advanced electronic control circuit ensures a fast response from 11 to 50 ms/volt and even with strong harmonic distortions, these devices ensure the true RMS value of the voltage. One of the main benefits of Enerdoor’s voltage stabilisers is when installed in existing systems these devices do not require new calculations for protection.

Voltage Stabilisers

Protect your equipment from harmful voltage fluctuations

Enerdoor offers an extensive range of single and three phase voltage stabilisers that regulate voltage through a series of transformers. A static control circuit drives the variable autotransformer that supplies the required voltage to a series transformer, either in phase or out of phase, to bring the mains to the rated value.

Voltage stabilisers protect electrical equipment from harmful high/low voltage fluctuations and at full load Enerdoor’s efficiency range is from 96% for small models to 98% for larger units. Enerdoor’s voltage stabilisers series ranges from a nominal voltage of 230-400Vac and rated power from 1-4000kVA.

Three Phase Voltage Stabilisers

Enerdoor’s three phase voltgae stabilisers are available in two versions: FINSTT and FINSTC.

They both perform voltage regulation by an average of three phases and are suitable for lines with balanced voltage and for an unbalance between phases up to 50%. These models are equipped with one stabilising circuit to ensure a common regulation of the three-phase and may be connected to input mains without neutral.
