What Is a Servo Type AVR?
A Servo Type AVR (Automatic Voltage Regulator) is an intelligent device that monitors and stabilizes input voltage using a servo motor-driven system. Unlike traditional relay-based regulators that switch in steps, servo AVRs provide continuous, smooth, and precise voltage adjustment—which is essential for sensitive loads like computers, refrigerators, televisions, and laboratory instruments.
The vertical type design with a digital display not only saves space but also gives users a clear view of voltage conditions and load status.

- Longer lifespan for connected devices
- More reliable performance under fluctuating or unbalanced loads
PREGUNTAS FRECUENTES
1. What’s the difference between a relay and servo AVR?
Relay AVRs switch voltage in fixed steps, which can be slow and imprecise. Servo AVRs, like SUNWAY’s, adjust voltage continuously using a motorized system, offering better accuracy and smoother operation.
2. Is the digital display accurate and useful?
Absolutely. Our digital display provides real-time voltage data, helping users monitor both the input and output voltage, load percentage, and fault conditions clearly and intuitively.
3. Can I use this AVR with solar inverters or generators?
Yes. SUNWAY servo AVRs are compatible with most generators and inverter systems, provided they fall within the input voltage and frequency range. Customization options are available if needed.
