IREM STEROSTAB Y — is a three-phase electromechanical voltage stabilizer with independent regulation of each of the three phases, designed to power the most demanding and sensitive equipment in unstable and distorted power grids. Manufactured in Italy by IREM, this stabilizer ensures the highest power stability for critical facilities.
Unlike models with general regulation (T series), the STEROSTAB Y voltage stabilizer automatically adjusts the voltage of each phase separately, ensuring maximum accuracy even with load imbalances of up to 100%. This is particularly important in industrial systems with uneven consumption or in networks where phase imbalances frequently occur.
Key advantages of the IREM STEROSTAB Y
- Independent stabilization for each phase — effective voltage compensation during phase imbalances and grid instability.
- Output voltage accuracy ±1% — ideal for powering precision equipment and electronics.
- Reliable overload capacity — withstands inrush currents and short-term overloads without losing stability.
- Smooth electromechanical regulation — no jerks or interruptions, does not generate electromagnetic interference.
- Silent operation — thanks to natural cooling, without fans or additional noise.
- Easy installation and maintenance — the stabilizer is designed for indoor installation and long-term, uninterrupted operation.
- High efficiency over 98.5% — economical energy consumption even in 24/7 operation.
- European quality — manufactured in Italy in compliance with ISO and CE certifications.
