ACI Constant Flow Variable Frequency Drive Fan Converter Adjustable

ACI Constant Flow Supply Blower Dedicated Converter

The constant flow supply type blower frequency converter is a frequency conversion speed control device designed specifically for fans, aiming to achieve constant control of the supply air volume by adjusting the fan speed. Its core function is to adapt to different working conditions, ensure stable air output of the fan, while also considering energy conservation, efficiency, and system stability..

Key functional features

• Constant flow control
  By using built-in flow sensors or pressure sensors (indirectly reflecting flow), combined with PID control algorithm, the fan speed can be adjusted in real time. When the system resistance changes, the frequency converter automatically adjusts the motor frequency to maintain a constant air output.
  The relationship between flow rate and speed: The air volume (Q) of the fan is directly proportional to the speed (n) (Q ∝ n), and the air volume can be precisely controlled by adjusting the speed.
  Pressure compensation: When the resistance of the pipeline changes, the speed is corrected through pressure feedback to avoid flow fluctuations.
• Variable frequency speed regulation technology
  Using AC-DC-AC frequency conversion method, the power supply is converted into AC power with adjustable frequency to drive the fan motor. Its core advantages include:
  Soft start: Reduce the starting current and minimize the impact on the power grid and machinery.
  Stepless speed regulation: Wide speed adjustment range, fast response speed, and strong adaptability.
  Energy saving effect: By reducing the speed and energy consumption, the energy saving rate can reach 20% -60% (depending on the operating conditions).
