FAQ's of Automatic Voltage Controller:


Q: How does the Automatic Voltage Controller maintain voltage stability in varying load conditions?

A: The controller uses a microprocessor-based, solid-state feedback mechanism that automatically detects and corrects voltage fluctuations at a typical rate of 35V/sec, ensuring stable output even during significant load changes.

Q: What are the available cooling options, and how do I choose between oil-cooled and air-cooled models?

A: Cooling type can be selected based on your operational environment and power rating. Oil-cooled models are suitable for higher power capacities and demanding conditions, while air-cooled versions are ideal for standard installations with moderate loads.

Q: When should I use the bypass arrangement, and what are its benefits?

A: The controller offers manual or automatic bypass to allow uninterrupted power supply during maintenance or in case of controller faults. Using the bypass ensures your critical operations continue without voltage control interruptions.

Q: Where can the Automatic Voltage Controller be installed, and what environmental considerations are required?

A: Designed for both indoor and outdoor use, the controller's enclosure offers protection up to IP54. It operates reliably at ambient temperatures from -10C to +55C and humidity up to 95% RH, with corrosion-resistant finish for harsh conditions.

Q: What monitoring and safety features are integrated into the controller?

A: The system includes digital/LED voltage displays, audio/visual alarms for abnormal conditions, over/under voltage and surge protection, plus optional remote monitoring via SCADA/BMS for enhanced safety and control.

Q: How can this voltage controller benefit my facility's equipment and operations?

A: By delivering stable voltage with negligible waveform distortion and over 98% efficiency, the controller reduces equipment wear, minimizes downtime, and optimizes power consumption, ensuring reliable and safe operation of your facility.
