Three Phase Servo Automatic Voltage Stabilizer Manufacturer

TNS6 Three Phase Servo Automatic Voltage Stabilizer

Ensure continuous, precision‑controlled power for high‑demand three‑phase loads with the TNS6 Three Phase Servo Automatic Voltage Stabilizer series. Designed for welding machines, CNC equipment, compressors, and other industrial applications, this three phase stabilizer maintains output voltage at 380 VAC (or customized) despite wide input fluctuations, safeguarding equipment performance and prolonging service life.

Core Benefits of the Three Phase Automatic Voltage Stabilizer

Servo Drive Precision Adjustment

Built-in servo motor adjusts high-precision transformer in real time, with output accuracy within ±3% of set value. Fast response (<1 second) instantly corrects voltage sags and spikes, ideal for sensitive industrial machinery.

Comprehensive Protection Suite

Overvoltage and Undervoltage Protection: Automatically disconnects when input voltage drifts beyond safe threshold (260-450VAC), and reconnects after a user-set delay.
Overload and Short-Circuit Protection: Intelligent current sensing shuts down output in overload or fault conditions to prevent damage.
Overtemperature Shutdown: Thermal sensor monitors internal temperature; integrated cooling fan and grille dissipate heat to keep noise at ≤50dB.

User-Friendly Monitoring and Control

Bright LED-LCD panel displays real-time input and output voltages, load percentage, and fault indicators.
Simple push-button controls allow operators to quickly set delay time and output voltage parameters.

Flexible installation and scalability

Available models: 20kVA, 30kVA, 40kVA, 50kVA, 60kVA, 80kVA, 100kVA, 120kVA.
Compact floor-standing design with casters for easy equipment mobility

Application Scenarios

Industrial Welding: Guarantees stable arc current and consistent weld quality by eliminating voltage dips during peak loads.
CNC & Machine Tools: Protects precision drives and control systems from fluctuations, reducing scrap rates and downtime.
Compressor & Pump Systems: Ensures reliable motor start‑up and operation in compressor rooms and water treatment facilities.
Packaging & Printing Lines: Maintains consistent motor speed and torque for high‑speed labeling, filling, and printing processes.

FAQs

Q1: How does the TNS6 three phase stabilizer differ from a static voltage regulator?
A1: Unlike static regulators that use thyristors or tap‑changer relays, the TNS6 Three Phase Servo Automatic Voltage Stabilizer employs a servo motor to adjust a precision transformer continuously. This design delivers smoother output, faster response, and higher durability under heavy industrial loads.

Q2: Can I customize the output voltage for non‑standard applications?
A2: Yes. While standard output is set to 380 VAC, we offer OEM customization for alternative voltages (e.g., 400 VAC, 415 VAC) and input ranges. Please contact our sales team to discuss minimum order quantities and configuration details.

Q3: What is the recommended stabilizer capacity for my welding machine?
A3: Calculate your welding machine’s maximum starting VA (volts × amps) and apply a 3× safety factor. For example, a machine drawing 30 A at 380 VAC requires 11.4 kVA; choose the next standard model, such as the TNS6‑20 kVA, to ensure reliable start‑up and continuous operation.

Enhance the stability and longevity of your three‑phase equipment with the TNS6 20 kVA–120 kVA Three Phase Servo Automatic Voltage Stabilizer.
