TND-SVC HIGH PRECISE SINGLE PHASE AUTOMATIC AC VOLTAGE REGULATOR

TND (SVC) series single-phase high-precision automatic AC voltage stabilizers consist of a contact-type auto-transformer, a servo motor, and an automatic control circuit. When the grid voltage is unstable or the load changes, the 1 automatic sampling control circuit sends a signal to drive 2 the servo motor, adjusting the position of the carbon brush on the auto transformer, thereby regulating the output voltage to the rated value and achieving a stable state. This product is characterized by no waveform distortion, reliable performance, and continuous long-term operation. It can be equipped with protection functions such as over-voltage, under-voltage, over-current, short circuit, surge, and delay as needed. It is widely suitable for various power supply environments requiring stable voltage and is an ideal voltage stabilizing power supply to ensure the normal operation of electrical equipment.

Features

▌Voltage Stabilizer Functions Features:

  • Automatic Voltage Regulator keeps your output voltage stable. This ensures your sensitive devices work in the stable voltage range. It also helps extend your equipment’s lifespan.
  • The AVR are designed to handle a wide input voltage range. They protect against both low and high-voltage fluctuations. This feature makes them suitable for areas with inconsistent power supply.
  • With a three-phase design, this AVR efficiently manages the voltage for three-phase electrical systems, ensuring balanced power distribution across all phases.
  • Usually comes with manual meters. But we can supply a built-in digital display that allows you to monitor the input and output voltage levels in real time, providing transparency and control over your power supply.
  • Achieving high output accuracy, minimizes voltage deviations, which can lead to equipment damage or malfunction. This feature is critical for industrial and commercial applications.
  • The AVR 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 AVR 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.
