10kVA Automatic Voltage Regulator

Voltage quality issues are often overlooked in small and medium-sized factories. Grid voltage fluctuations can cause CNC controllers to reboot, motor torque to become unstable, heating temperatures to deviate, and variable frequency drives (VFDs) to trigger alarm shutdowns—or even burn out power modules in severe cases. A single voltage spike can damage production equipment worth hundreds of thousands of yuan, while downtime across an entire production line caused by voltage sags can result in losses amounting to thousands of yuan per hour.

The AVS-10000 is designed to be installed downstream of the main factory distribution box, supplying power to all high-load equipment (such as air compressors, injection molding machines, central air conditioning, dryers, and lighting systems).

When the mains voltage fluctuates between 130V and 270V, the 10KVA Automatic Voltage Regulator automatically switches taps to ensure the output voltage remains stable within the safe range of 180–255V, maintaining an accuracy of ±8%. Its toroidal transformer boasts an efficiency of over 96%, ensuring it does not overheat even during prolonged full-load operation; the 50A resettable circuit breaker withstands the high inrush currents generated when starting multiple motors, preventing nuisance tripping.

Consider a small mold workshop equipped with 20 computers, 5 CNC machines, and 3 air conditioners: after installing the AVS-10000, equipment failures caused by voltage irregularities dropped from 12 incidents per year to just one, resulting in annual savings of over 50,000 RMB in maintenance costs and losses due to production downtime.

Key Features

1. High-Power Centralized Regulation

The AVS-10000 delivers 4800W of continuous active power, sufficient to handle the total load of most small factory facilities. It utilizes industrial-grade input/output terminal blocks, allowing users to connect 10mm² or 16mm² cables directly—eliminating the need for adapter sockets and ensuring safety and reliability.

2. 50A Industrial-Grade Circuit Breaker

Unlike household models, the AVS-10000 is equipped with a 50A thermal-magnetic circuit breaker that offers superior breaking capacity and surge current resistance. It can withstand inrush currents—up to 6–8 times the rated current for durations of less than one second—associated with starting three-phase motors, thereby preventing production disruptions caused by frequent tripping. 10KVA Automatic Voltage Regulator also provides precise overload protection: if the load continuously exceeds 4800W, the breaker trips within a timeframe ranging from a few seconds to tens of seconds, effectively protecting the transformer and electrical wiring.

3. 7-Tap Toroidal Transformer – Fast Response, Low Loss

· Tapped voltage design provides adjustment steps of approximately 15–20V per tap with a response time of <40ms.

· Toroidal structure minimizes magnetic leakage, preventing electromagnetic interference with nearby PLCs, sensors, and instrumentation.

· Natural cooling (fanless design) eliminates the risk of overheating shutdowns caused by fan failure.

· Supports 120% short-term overload (60 seconds) to accommodate peak power demands during production processes.

4. Comprehensive Protection and Monitoring

· Over-temperature protection: Automatically cuts off output if internal temperature reaches ≥120°C; automatically resumes operation once the temperature drops.

· Over-voltage/Under-voltage protection: Cuts off output if voltage falls outside the 180–255V range; automatically restarts (with a time delay) once voltage stabilizes.

· Short-circuit protection: Rapid tripping via a 50A circuit breaker.

· Delayed startup: Selectable 6-second (general equipment) or 180-second (compressors/refrigeration equipment) delay to prevent power surges caused by simultaneous startup.

· LED indicators and dual voltmeters: Real-time monitoring of input voltage, output voltage, and operating status, facilitating quick assessment by inspection personnel.

5. Rugged Tower Enclosure for Industrial Environments

Dimensions: 405×260×310mm; Net weight: 15.5kg; Metal housing with ventilation grilles on the front, back, and sides. Suitable for placement in distribution cabinets, on racks, or on the floor. Operating temperature: 0–40°C; Relative humidity: 10–90% (non-condensing); meets requirements for standard industrial facilities.

6. Seamless Integration with Generators and UPS

When switching to a generator due to mains instability or power outages, the generator's output voltage and frequency may fluctuate. Connecting the AVS-10000 downstream of the generator stabilizes the output voltage, protecting sensitive downstream equipment. It can also be connected in series with an online UPS—where the UPS provides battery backup and the AVS ensures voltage stability—creating a comprehensive power quality solution.

Product Applications

1. Small Factories / Processing Workshops

Scenario: Facilities equipped with 10–20 CNC machine tools, air compressors, dust extraction fans, lighting systems, and computers. Total load is approximately 4000W.

Solution: Install the AVS-10000 at the main distribution panel to provide voltage stabilization for all equipment. Results: Motors run smoothly, machining precision improves, and controllers no longer reboot unexpectedly.

ROI: Based on a reduction of five breakdown incidents per year—each costing 2,000 RMB in losses—the equipment cost is recovered within one year.

2. Large Cold Storage Facilities / Livestock Farms

Scenario: Multiple compressors, fans, heaters, and monitoring systems. Voltage fluctuations cause frequent compressor burnouts (repair cost: 3,000 RMB per unit).

Solution: Install one AVS-10000 to stabilize the power supply for the entire cold storage distribution panel, with a 180-second delay setting to protect the compressors.

Results: Compressor lifespan extends by 2–3 times; annual maintenance costs are reduced by over 10,000 RMB.

3. Communication Base Stations / Server Rooms

Scenario: Base stations containing switching power supplies, RRUs, BBUs, and air conditioning units. Mains voltage fluctuates significantly, ranging from 140V to 260V.

Solution: Pair the AVS-10000 with switching power supplies to ensure base station equipment operates within the normal voltage range, thereby reducing connection drop rates.

Results: Equipment failure rate drops by 70%; base station availability rises to 99.9%.

4. Commercial Kitchens / Large Restaurants

Scenario: Simultaneous use of multiple electric ovens, dishwashers, ice makers, and refrigerators causes severe voltage drops.

Solution: Use the AVS-10000 for centralized voltage stabilization to ensure stable voltage for all kitchen equipment, preventing issues such as insufficient oven temperatures and burnt-out dishwasher controllers.

Results: Consistent food preparation quality and significantly reduced maintenance costs.

5. Small Water Plants / Pumping Stations in Remote Areas

Scenario: Water pump motors overheat and burn out due to low voltage, disrupting the water supply. Solution: The AVS-10000 powers water pump control cabinets; it maintains a high output voltage even during voltage dips, ensuring reliable motor startup and operation.

Result: Extended continuous operation time for water pumps and reduced frequency of emergency repairs.
