What Is a Fan Speed Controller?

A Fan Speed Controller—also known as a fan controller or ventilation controller—is an electronic device that adjusts the speed of AC fans and motors. It works by regulating voltage or frequency, enabling precise control over airflow, noise levels, and energy consumption. This is ideal for applications where variable ventilation is required rather than fixed-speed operation.

Key Features & Specifications

United Automation’s fan speed control range includes units with features such as:

• Voltage regulation from 230 V AC
• Adjustable speed levels, typically 10–100% of full speed
• Compact form factor for DIN-rail mounting
• High inrush current protection to prevent motor damage
• Soft-start capability for smoother motor acceleration
• Built-in thermal or overload protection
• User-friendly controls, including potentiometers and digital interfaces
• Available in 1-phase and 3-phase models for varied fan types

These features ensure that fans run efficiently, safely, and quietly across diverse applications.
