Stabilizzatori di Tensione

If you're looking to protect equipment from voltage fluctuations, a voltage stabilizer is the perfect solution. Not only does it regulate the voltage supply, but it also protects against power surges and spikes that can damage equipment.

In addition to safeguarding devices, voltage stabilizers also increase their efficiency by ensuring they operate at the proper voltage level. By investing in a voltage stabilizer, you can extend the lifespan of your equipment and save money on repairs and replacements.

Enedoor offers a range of voltage stabilizers suitable for every industry and we offer a variety of models to fit your specific needs and budget. Trust us to safeguard your equipment and keep your power supply stable with our high-quality voltage stabilizers.

What is a Voltage Stabilizer?

It is an electrical device 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 and are 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.

High-Quality Voltage Stabilizers

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 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.

Benefits of Enerdoor Voltage Stabilizers:

• Protects electrical equipment from harmful high/low voltage fluctuations 
• At full load the efficiency range is from 96% for small models to 98% for larger units
• The advanced electronic control circuit ensures a fast response from 11 to 50 ms/volt
• Even with strong harmonic distortions, ensures the true RMS value of the voltage
• Operates correctly with a maximum environment temperature of 40°C
• When installed in already existing systems does not require new calculations for protection
