Voltage Stabilizers

Ensuring Consistent Power for Your Equipment

Voltage Stabilizer

Voltage stabilizers are the ideal solution for safeguarding equipment against voltage fluctuations, power surges, and spikes that can lead to damage. Not only do they regulate the voltage supply, but they also enhance efficiency by maintaining the proper voltage level, thus extending the lifespan of your equipment and reducing repair costs.

Enerdoor provides a comprehensive range of high-quality voltage stabilizers tailored to fit the specific needs and budget of every industry. Trust us to keep your power supply stable and your equipment protected.

What is a Voltage Stabilizer?

A voltage stabilizer is an electrical device that maintains a constant voltage at its output terminals, regardless of changes in the input or incoming supply voltage. It protects valuable electrical equipment from over-voltage, under-voltage, and voltage surges, making it an essential component for industrial and automated machinery.

Key Features of Enerdoor Voltage Stabilizers:

  • Specialization in single and three-phase voltage stabilizers utilizing a series of transformers.
  • Static control circuit driving a variable autotransformer for precise voltage regulation.
  • Models like FINSTT and FINSTC provide average three-phase regulation for balanced voltage lines.
  • Models like FINSTTY and FINSTCY offer individual phase regulation for unbalanced mains.
  • Protects against harmful voltage fluctuations with efficiency ranging from 96% to 98% at full load.
  • Fast response time from 11 to 50 ms/volt ensured by advanced electronic control circuit.
  • Maintains true RMS value of voltage even in the presence of strong harmonic distortions.
  • Operates correctly at a maximum environment temperature of 40°C.
  • Seamless integration into existing systems without requiring new protection calculations.
