SBW Fully Automatic Compensating Power Voltage Stabilizer

The SBW Fully Automatic Compensating Power Voltage Stabilizer (DBW/SBW series) is designed to deliver stable regulated output for demanding power systems and complex loads. Using a column type contact voltage regulator with all copper coils, it provides reliable long term operation and simplified adjustment, with support for unattended running. SBW models are designed for three phase unified adjustment (typical capacity 10kVA–6000kVA), while DBW models support single phase applications (typical capacity 10kVA–2000kVA). Standard frequency is 50Hz/60Hz, and efficiency can reach 98% (for power >50kVA). Operating Voltage Ranges are available with wide tolerance such as ±15% / ±20% / ±25% / ±30% (customizable), with common output options including 220V/380V (customizable). Output Voltage Accuracy is typically ±(2% to 5%) adjustable, waveform distortion can be 0.1% or less, and response time can be <1.5s when input voltage changes by 10%. Integrated protections (over/under voltage, overload, overcurrent, phase loss for 3 phase) plus automatic/manual bypass help ensure continuous power supply. Typical application fields include industrial equipment, power systems, commercial facilities, and critical loads requiring stable voltage. (Specifications can be customized—please confirm final data when ordering.)

Key Features
