Three-Phase Fan Motor Controller 380V 6A Manual Speed – 2.2KW
Three-Phase Fan Motor Controller 380V 6A Manual Speed – 2.2KW
Three-Phase AC Fan Motor Controller – 380V, 6A, Up to 2.2KW
Take precise control of your three-phase AC fans with this robust aluminum-housed motor controller. Featuring a manual rotary knob for stepless speed adjustment, it delivers smooth, continuous airflow regulation from approximately one-third of rated speed all the way up to full speed — no complicated programming or VFD required.
Key Features
- Simple 3-Wire Input & Output Wiring – Connects directly to three-phase 380V live wires. No neutral or ground wire needed through the terminals; simply secure a wire to any exposed metal part of the housing for grounding. Output connects straight to your three-phase fan motor. If the fan rotates in the wrong direction, just swap any two output wires.
- Manual Stepless Speed Control – The rotary knob provides infinitely variable speed adjustment, giving you precise airflow volume control across the full operating range.
- Solid Power Handling – Rated at 6A and supports motors up to 2.2KW, making it well-suited for most small-to-medium three-phase AC fan applications in industrial and commercial environments.
- Thyristor (Power Regulation) Design – Operates on a proven power-regulation principle for smooth, reliable speed transitions. Note: this is not a Variable Frequency Drive (VFD); it is optimized specifically for fan-type loads.
- Wide Fan Compatibility – Designed for three-phase 380V AC fans with blades, including purification fans, air conditioning branch fans, axial fans, and standard ceiling fans. Not suitable for non-fan loads or equipment without fan blades. (Compatibility may vary by fan model.)
- Durable Aluminum Housing – Compact 150×75×45mm casing dissipates heat effectively and withstands demanding workshop or industrial conditions.

Frequently Asked Questions
Q: Can this three-phase fan motor controller work with any three-phase motor?
A: No — this controller is specifically designed for three-phase 380V AC fan motors with blades (such as axial fans, purification fans, and air conditioning branch fans). It uses a thyristor power-regulation design optimized for fan-type loads only. It is not compatible with non-fan loads, motors without blades, or general-purpose three-phase motors. Always verify compatibility with your specific fan model before installation.
Q: What is the difference between this controller and a Variable Frequency Drive (VFD)?
A: This controller operates on a thyristor (SCR) power-regulation principle, which adjusts the voltage supplied to the motor to control speed. A VFD, by contrast, changes the output frequency. This unit is simpler, more compact, and lower cost for fan-only applications, but it does not provide the full torque range or motor protection features of a VFD. It is best suited for straightforward fan speed control in industrial or commercial settings.
Q: How do I reverse the fan rotation direction?
A: If your fan rotates in the wrong direction after wiring, simply swap any two of the three output wires connected to the fan motor. This reverses the phase sequence and changes the motor's rotation direction — no additional components are required.
Q: Does this controller require a neutral wire for installation?
A: No neutral wire is required for the input or output terminals. The unit connects directly to the three live phases of a 380V three-phase supply. For grounding, secure a ground wire to any exposed metal part of the aluminum housing.
