Protect Equipment From Harmful Voltage Fluctuations

Voltage Stabilizer

A voltage stabilizer is an electrical appliance that delivers a constant voltage to a load at its output terminals, regardless of the changes in the input or incoming supply voltage. It protects equipment or machinery against over voltage, under voltage, and other voltage surges.  They are often used for costly and precious electrical equipment to protect them from harmful high/low voltage fluctuations. This is ideal for industrial and automated machinery.

Electrical equipment is designed for a wide range of input voltage. Depending on the sensitivity, the working range of equipment is limited to a specific value, for instance, some equipment may tolerate ± 10 percent of the rated voltage, while others may tolerate only ± 5 percent or less.

Enerdoor specializes in single and three phase voltage stabilizers 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 to bring the main to the rated value. 

Three-phase stabilizers are available in two versions:
The models FINSTT and FINSTC 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 stabilizing circuit to ensure a common regulation of the three-phase and may be connected to input mains without neutral.

The models FINSTTY and FINSTCY are equipped with one stabilizing circuit for each phase and are suitable for unbalanced mains with a maximum unbalance between phases up to 100%. For correct operation, the input line must be three-phase + neutral. Voltage regulators do not transform the voltage and therefore have the same output voltage as the input. When input and output voltages are different, an additional isolating transformer or auto-transformer is required.
