Product Overview

Core Specifications

  • Model: TND (SVC)-5000VA
  • Rated Capacity: 5000VA (5KVA)
  • Recommended Load:
    • Resistive load: ≤4000W
    • Inductive load: ≤2500W

Working Principle

This stabilizer uses a servo motor control system to detect voltage fluctuations in real time. When the input voltage deviates from the normal range, the motor automatically adjusts the carbon brush position on the transformer winding.

This dynamic adjustment stabilizes the output voltage, ensuring consistent and safe power supply for connected devices.
