20kVA Servo Motor AVR

The SVC-20KVA is the heavy-duty workhorse of the SVC series, delivering 20KVA of stabilized power for the most demanding industrial and commercial applications. Built around a robust servo motor transformer and carbon brush regulation system, the unit's CPU-controlled circuit board continuously monitors input voltage and precisely adjusts the carbon brush position to maintain stable output. The result is a stable 220V±3% output even when input voltage fluctuates between 80V and 260V.

With a Grade A isolation transformer rated at AC 2000V/1min dielectric strength, the SVC 20KVA Servo Motor AVR provides exceptional electrical safety for heavy industrial loads. The unit's near-zero waveform distortion (<0.1%) ensures that sensitive control equipment receives clean power, while the heavy-duty construction and intelligent cooling system ensure reliable operation under continuous heavy loads. The LCD display provides real-time system status visibility, and the comprehensive protection suite safeguards both the regulator and connected equipment.

Core Advantages

1. High Capacity for Heavy Loads (20KVA)

With 20KVA capacity, the SVC-20KVA can handle the combined loads of multiple large appliances – industrial freezers, commercial air conditioners, manufacturing equipment, and whole-building electrical systems. This capacity makes 20KVA Servo Motor AVR suitable for factories, warehouses, and large commercial facilities.

2. Exceptional Thermal Management

The unit features an intelligent cooling fan and a built-in temperature sensor in the transformer coil. The net temperature rise is kept below 60°C, ensuring reliable operation even under continuous full-load conditions.

3. Ultra-Wide Input Range (140-260V)

The SVC-20KVA accepts input voltages from 80V to 260V, making it suitable for industrial locations with severely unstable grid power. This wide range ensures that your critical equipment remains protected even during extreme grid fluctuations.

4. Rapid Response (0.1s) with High Precision

With a response speed of 0.1 seconds and ±3% output precision, the unit reacts instantly to voltage changes, preventing even momentary disruptions from affecting industrial processes.

5. Industrial-Grade Construction

Built with a pure copper winding toroidal transformer and housed in a durable 500×380×620mm chassis, the SVC-20KVA is designed for the harsh conditions of industrial environments. At 65kg, it is built to last.

6. Comprehensive Protection for Valuable Equipment

The unit features overload protection (trips at 120% load), over-voltage protection, under-voltage protection, short-circuit protection, and overheat protection. The Grade A isolation transformer provides AC 2000V/1min dielectric strength, ensuring no flashover or breakdown.

Product Parameter

Key Application Scenarios

1. Manufacturing Facilities – Protect CNC machines, conveyor systems, welding equipment, and automated production lines from voltage fluctuations that could cause production downtime or equipment damage.

2. Commercial HVAC Systems – Stabilize voltage for large air conditioning units, chillers, and heating systems in commercial buildings, preventing compressor failures and extending equipment life.

3. Industrial Freezers and Cold Storage – Safeguard large refrigeration systems in food processing plants, warehouses, and cold storage facilities, where voltage fluctuations could lead to costly inventory loss.

4. Whole-Building Voltage Management – For large commercial buildings, the SVC-20KVA provides comprehensive voltage stabilization for all electrical systems, protecting against grid instability.

5. Elevators and Lifts – Protect elevator motor drives and control systems from voltage sags and surges that could cause safety issues or service interruptions.

Why Choose the SVC-10KVA?

The SVC-20KVA offers 100% more capacity than the 10KVA model and 33% more than the 15KVA model, making 20KVA Servo Motor AVR the only choice for heavy industrial and large commercial applications. Its higher capacity allows it to handle the combined loads of multiple large appliances simultaneously, while its robust construction and intelligent cooling ensure reliable operation under continuous heavy loads. For facilities where power stability is critical to operations and downtime is not an option, the SVC-20KVA is the definitive solution.
