Low Voltage Stabilizer

The DBW/SBW series low voltage stabilizers provide advanced, fully automatic compensation for voltage fluctuations in single-phase and three-phase AC networks. Engineered with high capacity, excellent efficiency, low waveform distortion, and rapid response time (<1.5s), they deliver stable voltage output even under varying load conditions. Built with protective features against over-voltage, under-voltage, over-current, and phase failure, they ensure reliable performance for sensitive equipment.

Suitable for a wide range of applications including industrial machinery, medical equipment, textile plants, elevators, HVAC systems, data centers, and lighting systems, the DBW/SBW series can operate continuously under demanding conditions.

Key Advantages:

High voltage stabilization accuracy: ±2–5% (adjustable)
Efficiency ≥95% (for units above 50 kVA)
Automatic or manual start options
Compact design for easy installation and maintenance
Strong overload capacity (up to 2× rated current)
Long-term unattended operation
