TNS-SVC HIGH PRECISE THREE PHASE AUTOMATIC AC VOLTAGE REGULATOR

The TNS series high-precision fully automatic three-phase AC voltage stabilizer is composed of three sets of TND (SVC) series high-precision fully automatic single-phase AC voltage stabilizers. Each phase is regulated separately, ensuring stable and safe voltage for each phase. The grid input is a three-phase four-wire system with a star (Y) connection, and the output can be either a three-phase four-wire system or a three-phase three-wire system. This product features non-distorted waveforms, reliable performance, and can operate continuously for extended periods. It can be equipped with optional protection functions such as overvoltage, undervoltage, overcurrent, phase loss, short circuit, surge, and delay. It is widely applicable to any environment requiring stable voltage, making it an ideal voltage stabilization power supply to ensure the normal operation of your electrical equipment. Customizable input with a delta connection is available.

Features

▌Voltage Stabilizer Functions Features:

  • stabilizes voltage, protecting sensitive devices and enhancing equipment longevity.
  • handle wide input voltage fluctuations, protecting against both low and high voltage, and are suitable for unstable power areas.
  • three-phase design, stabilizes voltage and ensures balanced power delivery to each phase of your electrical system.
  • built-in digital display for real-time voltage monitoring, ensuring transparent power supply control.
  • Achieving high output accuracy, minimizes voltage deviations, which can lead to equipment damage or malfunction. This feature is critical for industrial and commercial applications.
  • Acts as a guard for your equipment against voltage spikes. It protects your valuable electrical loads from sudden voltage fluctuations or electrical storms.
  • Built-in overload protection safeguards the voltage stabilizer and connected devices from excessive electrical loads, preventing overheating or equipment damage.
  • Equipped with advanced servo motors, these regulators respond rapidly to voltage fluctuations, ensuring seamless power transitions without interruptions.
  • Engineered for quiet operation, making them suitable for diverse settings, including office environments and industrial facilities.

▌Protection Function:
☑Overload Protection:
When the load power reaches 120%, the voltage stabilizer automatically activates protection, cutting off the output.
☑Overvoltage Protection:
When the output phase voltage exceeds 250V, the overvoltage indicator lights up, and the output is automatically cut off.
☑Undervoltage Protection:
When the output voltage drops below 184V, the undervoltage indicator lights up, and the output is automatically cut off.
☑Delay Protection:
Upon power-up, a delay of several seconds is automatically initiated before voltage stabilization begins.
☑Short Circuit Protection:
When a short circuit occurs, the voltage stabilizer automatically stops output and requires manual reset to restore output.
☑Over temperature protection:
Over-temperature protection will shut down the regulator if it exceeds a safe operating temperature, preventing damage to its internal circuitry.

▌Product Characteristics:

  1. Rapid Voltage Stabilization:
  2. 0.01-second response time for instantaneous voltage stability.

  3. Independent Control:
  4. 6 high-power coils, three-phase independent control, independent output, ensuring stable voltage for each phase.

  5. Precise Output:
  6. Intelligent chip independently and accurately controls each phase voltage, outputting a precise and stable 380V.

  7. High-Quality Coils:
  8. Uses high-quality pure purple copper voltage regulating coils, tightly wound, excellent core quality, stable and reliable performance.

  9. Long-Life Carbon Brushes:
  10. Uses 1017 carbon brushes, more precise voltage regulation, no tripping, stable performance, service life up to 8 years.

▌Application:
This series of voltage stabilizers is widely used in industrial, agricultural, medical, broadcasting, telecommunications, scientific research, cultural fields, and other areas where small and medium-sized electromechanical equipment, production lines, construction machinery, microcomputers, embroidery machines, air conditioners, refrigerators, audio equipment, televisions, and other household appliances, lighting, and other equipment requiring voltage stabilization are used.
