20KVA Three Phase Servo Controlled Stabilizer

A 20 kVA Three-Phase Servo Controlled Voltage Stabilizer is a high-performance solution designed to provide stable and precise voltage regulation for a wide range of industrial, commercial, and sensitive equipment. It uses advanced servo technology to maintain consistent voltage, protecting machinery and devices from the damaging effects of voltage fluctuations, surges, and sags.

1. Power Rating:

   • 20 kVA capacity, making it ideal for small to medium-sized industrial machinery, HVAC systems, medical equipment, and sensitive electronics.

2. Servo Control Mechanism:

   • Motorized Variac: The servo motor adjusts the variac (variable transformer) to correct input voltage fluctuations in real-time.
   • Fast Correction: Typically corrects voltage in 20–40 ms per volt, ensuring quick stabilization to avoid equipment damage.

3. Voltage Range:

   • Input Voltage: 340V–460V (customizable as per requirements).
   • Output Voltage: 400V ± 1% (adjustable), ensuring precision for sensitive equipment.

4. Three-Phase Stability:

   • Designed for 3-phase systems, ensuring balanced voltage across all phases for consistent power distribution.
   • Phase Sequence Protection: Ensures correct phase sequence and protects against phase reversal.

5. Protection Features:

   • Overload Protection: Prevents damage to the stabilizer and connected equipment from excessive load.
   • Short-Circuit Protection: Safeguards the system from electrical faults.
   • Over-voltage and Under-voltage Protection: Automatically disconnects during extreme voltage conditions to prevent equipment damage.
   • Phase Failure Protection: Disconnects when a phase failure or imbalance occurs.

6. High Efficiency:

   • 95–98% Efficiency: Ensures minimal power loss during voltage stabilization, reducing operational costs.

7. Cooling System:

   • Typically air-cooled for effective heat dissipation in standard environments. Oil-cooled options may be available for heavier duty applications.

8. User Interface:

   • Digital Display: Real-time monitoring of input/output voltages and load current.
   • Alarm Indicators: For faults such as overload, under-voltage, and phase failure.

9. Compact & Robust Construction:

   • IP21/IP55 Enclosure Options: Ideal for indoor or outdoor use with high dust and water resistance for challenging environments.
   • Durable Build: High-quality materials for long-lasting performance.

• Industrial Equipment: Protects CNC machines, industrial motors, and automation systems from voltage irregularities.
• Commercial Buildings: Ensures reliable power for HVAC, lighting, and critical power systems.
• Data Centers: Prevents damage to servers, routers, and networking equipment caused by power fluctuations.
• Medical Devices: Provides stable voltage for sensitive medical equipment such as diagnostic devices, X-ray machines, and MRI scanners.
• Telecommunication: Ensures stable power for telecom infrastructure, preventing network downtime.
• Laboratories: Stabilizes voltage for scientific equipment and instruments.
