SHTEEL series voltage stabilizers — a modern solution for three-phase power grids, which are increasingly used in cottages, apartment buildings, and industrial facilities. They are designed to ensure a stable and reliable power supply for critical equipment and machinery.
Compatible with modern inverters
In addition, these stabilizers are easily integrated into modern uninterruptible power supply systems. They work perfectly with inverters from Deye, Victron Energy and other popular brands, ensuring maximum stability of your home or industrial power grid.
Why choose SHTEEL three-phase voltage stabilizers?
- Fast response time — 20 ms — instant reaction to changes in grid parameters.
- Reliable protection against overvoltage, overheating, short circuits, and overloads.
- Digital monitoring: voltmeters, power meter (kW), microprocessor control.
- “Transit” mode — for operation without stabilization when needed.
- WEB interface (optional) — control of the stabilizer via a PC or smartphone.
- Compatibility with generators and hybrid systems, including solar power plants.
- Synchronizers (optional) — protection in case of single-phase failure.
- Quality proven over the years — over 15 years of serial production.
