Compensated Voltage Regulator

The DBW/SBW series is designed to keep output voltage stable when the external power grid fluctuates or when load conditions change frequently. By combining automatic compensation, smooth voltage regulation, and reliable electrical protection, the unit helps equipment operate safely in factories, commercial buildings, public facilities, and power distribution rooms.

As a Compensated Voltage Regulator solution, this series supports single phase and three phase applications, with capacity options from small commercial installations to high-power industrial systems. Compared with conventional stabilizers, it offers large capacity, high efficiency, no additional waveform distortion, stable regulation, compact structure, and dependable continuous operation.

• Single and three phase options: DBW models are suitable for single phase systems, while SBW models support three phase power supply requirements.
• Wide input voltage adaptability: Designed for grid fluctuation environments, helping maintain a stable output voltage for connected equipment.
• Adjustable output accuracy: Output accuracy can be adjusted within 1-5% to match different application requirements.
• High efficiency operation: Efficiency is greater than 95% for models above 50 kVA, reducing unnecessary power loss in long-running systems.
• Fast voltage response: Response time is within 1.5 seconds, supporting stable operation when load or grid voltage changes.
• Reliable protection functions: Built-in protection for overvoltage, overcurrent, phase loss, phase sequence, and mechanical faults.
• Practical installation and maintenance: Cabinet-style design, clear panel indicators, and manual/automatic switching support easier operation and service.

The DBW series covers common single phase power ratings from 20 kVA to 200 kVA. The SBW series covers three phase ratings from 50 kVA to 600 kVA, with SBW-F high-capacity models available from 800 kVA to 2000 kVA. Product dimensions and net weight vary by model and capacity.

This voltage stabilizer is suitable for locations where normal operating voltage must be protected from grid fluctuation, unstable supply conditions, or sudden load changes.

• Post and telecommunications facilities
• Shopping malls and commercial buildings
• Elevators and building service systems
• Hospitals, schools, printing facilities, and securities offices
• Large and medium-sized industrial workshops
• Partial power supply systems and important equipment matching
• Factory distribution rooms and OEM electrical projects

To select the right model, confirm the required phase type, rated capacity, input voltage range, output voltage, load characteristics, installation environment, and protection requirements. For projects with large motors, frequent load changes, or unstable grid conditions, reserve suitable capacity margin to support long-term stable operation.
