IREM STEROSTAB T — an industrial-grade three-phase voltage stabilizer with simultaneous regulation of all three phases. Designed and manufactured in Italy by IREM, it is intended to power critical equipment that requires high-precision voltage stabilization in unstable power grid conditions.
Unlike residential models, STEROSTAB T ensures output voltage stability with an accuracy of ±1% even during severe grid fluctuations, allowing for up to 50% phase load imbalance. It is ideal for facilities where the three-phase load is generally balanced or pre-adjusted, as well as for powering induction motors, automation lines, and pumping and ventilation equipment.
Key Benefits of the IREM STEROSTAB T
- Three-phase overall regulation — synchronous voltage stabilization across all phases is suitable for balanced networks with centralized load control.
- High accuracy — the output voltage is maintained within ±1% RMS, ensuring safe and efficient operation of critical equipment.
- Reliable overload capacity — the stabilizer can withstand 10-times short-term loads, which is especially important when starting powerful motors.
- Continuous electromechanical correction — no voltage spikes, interference, or power interruptions during voltage fluctuations.
- Silent operation — cooling is achieved through natural ventilation without the use of fans.
- High efficiency >98.5% — efficient energy use, minimal losses during stabilization.
- European quality — manufactured in Italy in accordance with international ISO and CE standards.
