Advanced Voltage StabilizationThis Automatic Voltage Controller ensures consistent output voltage for demanding industrial and commercial environments. With a rapid response time of less than 10 milliseconds, it automatically compensates for voltage fluctuations, thus protecting sensitive equipment and reducing downtime. Microprocessor or digital control systems monitor performance, ensuring precision and reliability with each voltage correction.
Superior Build and Protection StandardsBuilt using copper windings and a CRGO core, the device delivers over 98% efficiency while maintaining low noise (<55 dB at 1 meter) and minimal waveform distortion. Its enclosure is engineered for durability, with options for Class F/H insulation and IP-21 degree of protection. These features ensure safe and continuous operation even in humid and rigorous industrial settings.
Flexible Installation and CustomizationAvailable in multiple configurations, the voltage controller can be floor-mounted and customized for color, dimensions, and power ratings (up to 5000 kVA). Choices of input/output connections (bus bars or cable lugs) streamline installation for new or retrofit projects. Manual and automatic bypass arrangements offer added convenience for maintenance or emergency situations, ensuring operational continuity.
FAQ's of Automatic Voltage Controller:
Q: How does this Automatic Voltage Controller stabilize voltage in industrial settings?
A: The controller continuously monitors input voltage and automatically adjusts it within milliseconds (response time <10 ms) using a microprocessor or digital controller. This ensures stable output voltage, typically 400V, to protect connected equipment from voltage fluctuations.
Q: What cooling options are available for this transformer?
A: The voltage controller offers ONAN (Oil Natural Air Natural) or air-cooled cooling systems, allowing optimal heat dissipation in both heavy-duty and standard operations. The specific option can be selected based on the installation environment and required thermal management.
Q: When should the manual or automatic bypass arrangement be used?
A: Manual or automatic bypass is useful during maintenance, servicing, or in case of controller malfunction. Switching to bypass ensures uninterrupted power to connected loads while the main unit is serviced or inspected, minimizing operational downtime.
Q: Where can this voltage controller be installed?
A: The device is designed for floor mounting and is suitable for both industrial and commercial environments across India. Its enclosure and protection class allow installation in areas with up to 95% humidity and temperatures between 0C to 50C.
Q: What are the benefits of using a copper-wound, CRGO core transformer in this controller?
A: Copper windings and a CRGO (Cold Rolled Grain Oriented) core boost electrical efficiency (>98%), minimize losses, and ensure robust performance, making the controller suitable for large, sensitive, or high-value equipment requiring reliable voltage regulation.
Q: How does the controller ensure safety and equipment protection?
A: The unit includes over and under voltage protection, high-grade insulation (Class F/H), IP-21 enclosure, and automatic response to voltage variations. These safeguards protect both the controller and the connected load from electrical hazards and ambient influences.
Q: What customization options are available for this voltage controller?
A: Customers can specify color, dimensions, rated power (up to 5000 kVA), input/output connections, and degree of protection as per site requirements. This flexibility accommodates a wide variety of industrial and commercial setups.
