Automatic Voltage Regulator (AVR) 500VA to 150KVA for Industrial & Commercial Use

Automatic Voltage Regulator (AVR) 500VA to 150KVA for Industrial & Commercial Use

Single-Phase Voltage Regulator 500VA–150KVA

Whether you are protecting a sensitive laboratory instrument or powering a heavy industrial manufacturing line, our comprehensive range of single-phase voltage regulators delivers unmatched stability. Engineered for extreme durability and precision, covering capacities from 500VA up to a massive 150KVA.

Product Introduction

In modern electrical networks, voltage instability poses a severe threat to both delicate electronics and massive industrial machinery. Voltage sags, surges, and continuous fluctuations lead to costly downtime, degraded product quality, and catastrophic equipment failure.

Our Single-Phase Voltage Regulator Series (500VA–150KVA) is engineered to solve these challenges across the entire power spectrum.


For Light Loads (500VA – 15KVA): We offer compact, low-noise, and highly precise stabilizers perfect for medical devices, IT servers, and commercial offices.


For Heavy-Duty Loads (20KVA – 150KVA): We provide rugged, high-overload-capacity floor-standing cabinets designed for heavy manufacturing, large-scale HVAC systems, industrial testing benches, and mining operations.


Utilizing advanced servo-motor or SCR (thyristor) control technologies, our stabilizers continuously monitor the grid and instantly correct voltage deviations, ensuring your equipment receives a pure, stable sine-wave output 24/7.


Key Features by Capacity Tier

🟢 Light & Medium Duty (500VA – 30KVA)

  • High Precision: Output voltage accuracy of ±1% to ±3%.
  • Quiet Operation: Natural cooling or low-noise fans for office and lab environments.
  • Compact Footprint: Wall-mounted or small cabinet designs to save space.
  • Fast Response: Instantly corrects grid fluctuations to protect sensitive PLCs and medical scanners.

🔴 Heavy-Duty Industrial (40KVA – 150KVA)

  • Massive Overload Capacity: Built to withstand 150% to 200% short-term overload (e.g., heavy motor starting currents).
  • Rugged Enclosures: IP20 to IP54 rated floor-standing steel cabinets designed for harsh factory environments.
  • Advanced Cooling: High-efficiency forced-air cooling systems with thermal protection for continuous 24/7 heavy loads.
  • Heavy-Duty Connections: Equipped with industrial busbars and heavy-duty terminal blocks to handle extremely high amperage (up to ~600A+).
  • Grid Balancing Options: For ultra-high single-phase loads (100KVA+), we offer specialized configurations to draw power from a 3-phase grid to prevent utility imbalance.

FAQ

Q1: Can you supply a 100KVA or 150KVA single-phase stabilizer?A: Yes. We manufacture heavy-duty single-phase units up to 150KVA. Because these units handle extremely high amperage, they are built as floor-standing cabinets with heavy-duty copper busbars. Please contact our engineering team for custom sizing and wiring diagrams.
Q2: My factory has a 3-phase grid, but I need a massive single-phase load. Can you help?A: Yes. Drawing 100KVA+ from a single phase of a 3-phase grid can severely unbalance the utility transformer. We offer specialized configurations (such as 3-phase input to single-phase output Scott-T transformers or specialized AVRs) to balance the load on the grid while providing stable single-phase power to your machine.
Q3: What is the difference between Servo and SCR (Static) control?A: Servo motor stabilizers use a mechanical arm to adjust the voltage. They are highly precise and cost-effective. SCR (Static) stabilizers use electronic thyristors to adjust voltage instantly with no moving parts. SCR is recommended for extremely fast voltage dips or heavy industrial environments where mechanical wear is a concern.
Q4: Do these units generate a lot of noise?A: Units under 10KVA are virtually silent. Heavy-duty units (50KVA–150KVA) use industrial cooling fans and will generate a low hum, similar to a large server rack or industrial transformer. They are designed for factory floors rather than quiet offices.
