Reliable Voltage Stabilization

Our servo voltage controller is engineered to provide highly stable output voltage (415 V AC) even when input fluctuates between 340-460 V AC. Its digital microprocessor-based system ensures real-time corrections, maintaining equipment safety and uninterrupted performance. With negligible waveform distortion and over 98% efficiency, this solution is ideal for sensitive or high-value electronic devices.


Robust Protection Features

The controller is fortified with features like built-in surge suppression, short circuit and overload protection, and under/over voltage safeguards. Heavy-duty electromagnetic relays and a high insulation resistance (2 Megohm) add an extra layer of reliability. LED/alarm buzzer indicators promptly alert users to any operational faults, supporting proactive maintenance.


Flexible Installation and Monitoring

For versatile applications, this voltage controller is available as both wall mounted and floor mounted. It's suitable for indoor settings with a compact footprint (690 x 760 x 425 mm) and offers optional remote monitoring for enhanced operational oversight, making it perfect for a variety of installations across industries.

FAQ's of Servo Voltage Controller:


Q: How does the servo voltage controller maintain output voltage accuracy?

A: The controller utilizes a digital microprocessor-based system that constantly monitors and corrects output voltage at a speed of 35 V/sec. This precise regulation ensures output voltage stays within 1% of the set value, even with input voltage variations from 340 to 460 V AC.

Q: What protection mechanisms are built into this voltage controller?

A: It features multiple protections, including short circuit protection, overload protection, surge suppression, and under/over voltage cutoff. Alarms and LED indicators notify users of faults, ensuring fast response and increased equipment safety.

Q: When should I use a servo voltage controller in my installation?

A: Use a servo voltage controller when your electrical equipment requires stable voltage for optimal performance and safety-especially in regions with frequent voltage fluctuations or environments with sensitive electronics.

Q: Where can this controller be installed?

A: The unit is designed for flexible installation, supporting both floor standing and wall mounted configurations. Its compact, IP21-rated enclosure is suitable for use in industrial, commercial, and residential settings.

Q: What are the benefits of copper wound transformers in this controller?

A: Copper wound transformers offer superior conductivity, increased efficiency, and enhanced durability. This design choice contributes to over 98% operational efficiency and a longer lifespan for the voltage controller.

Q: How does remote monitoring enhance user control?

A: The optional remote monitoring feature allows operators to track voltage conditions and faults in real time, enabling quicker maintenance and minimizing downtime. This is particularly advantageous for large-scale or critical installations.
