The DBW series compensating voltage regulator (AVR) is a new generation power regulator developed by our company, utilizing U.S. technology and tailored to the actual voltage conditions of domestic power grids. This regulator automatically maintains stable output voltage when external power grid voltage fluctuates or when load changes.

Key advantages include large capacity, wide range, low loss (energy-saving type), high accuracy, fast voltage adjustment speed, and no waveform distortion.

It offers smooth voltage regulation, can handle instantaneous overloads, and is suitable for various linear and nonlinear loads.

The user-friendly Chinese LCD display facilitates ease of use and maintenance.

The power devices within the DBW series compensating AC voltage regulator cabinet utilize forced air cooling, with air intake from the bottom and exhaust from the top, employing axial flow AC fans that have a continuous operating life of no less than 50,000 hours (GB/T2658). The cooling air flow for each 40 kVA output capacity regulator cabinet is no less than 15 m³/min.
