Non-Contact Compensating AC Voltage Stabilizer

Continuously monitoring the input voltage of the power grid line, the voltage detection unit converts any voltage changes into digital signals. These signals are then processed by the microcontroller, guided by preprogrammed instructions and predefined data. The intelligent control system then transmits commands to the optocoupler, activating the contactless and swift electronic switching circuit to precisely adapt the output voltage. This ensures that the output voltage remains within the acceptable error range, effectively maintaining automatic voltage stabilization.

  • Input Frequency50/60Hz
  • Efficiency≥98%
  • Voltage Stabilizing Accuracy±2%
  • Response Speed<10ms or <20ms
A Non-Contact Voltage Stabilizer, also known as an Electronic Voltage Stabilizer or Solid-State Voltage Stabilizer, is a type of voltage regulation device that maintains a stable output voltage without direct physical contact with the electrical supply. Unlike traditional voltage stabilizers that use mechanical components such as transformers and servo motors, non-contact voltage stabilizers rely on electronic circuitry to achieve voltage regulation.

Key Features: Non Contact Voltage Stabilizer

  1. Electronic Circuitry: These stabilizers use semiconductor devices, such as transistors and integrated circuits, to regulate and stabilize the output voltage.
  2. Fast Response Time: Non-contact voltage stabilizers typically have a fast response time, providing quick and precise adjustments to changes in input voltage. This rapid response helps protect connected equipment from sudden voltage fluctuations.
  3. Compact Design: The electronic nature of these stabilizers allows for a more compact and lightweight design compared to traditional stabilizers. This makes them suitable for applications where space is limited.
  4. Efficiency: Non-contact voltage stabilizers are often more energy-efficient than traditional models. They can adjust the voltage with high precision, minimizing energy losses during stabilization.
  5. Wide Input Voltage Range: Many non-contact voltage stabilizers are designed to operate over a wide range of input voltages, providing stability even in regions with significant voltage fluctuations.
  6. Microprocessor Control: Some advanced non-contact voltage stabilizers utilize microprocessor control for enhanced accuracy and additional features. Microprocessors can analyze input voltage conditions and adjust the stabilizer accordingly.


  1. Emergency Services:  Equip emergency response vehicles, such as ambulances and mobile command centres, with non-contact voltage stabilizers to ensure the continuous operation of communication and medical equipment during critical situations.
  2. Oil and Gas Industry: Protect electronic controls and monitoring systems in drilling rigs and extraction equipment from voltage fluctuations, contributing to the safety and efficiency of operations in the oil and gas industry.
  3. Transportation Systems: Ensure the reliable operation of traffic lights, signals, and control systems by stabilizing voltage in transportation infrastructure, contributing to smooth traffic flow and safety.
  4. Water Treatment Plants: Stabilize voltage in the control systems of water treatment plants to maintain the efficient operation of pumps, sensors, and monitoring equipment, ensuring the delivery of clean and safe water.
  5. Broadcasting and Media: Protect broadcasting equipment, including cameras, audio consoles, and transmitters, from voltage fluctuations to maintain the quality and reliability of television and radio broadcasts.
