Three-phase voltage stabilize RETA ННСТ-3x5.5 kW SHTEEL 25A MCMA 110a (IXYS) + WEB interface 7-0

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.

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.
