Three-Phase Asynchronous Fan Controller

Stable Control Solution for Standard Induction Fans

This Three-Phase Asynchronous Fan Controller is developed by Wuxi Ruisida Electric. It is designed for industrial ventilation systems using three-phase induction motors.

The controller is a sealed industrial-grade unit suitable for dust, moisture, and harsh factory environments.

It adopts a V/F (Voltage/Frequency) control algorithm optimized for asynchronous motor applications. The system ensures smooth start-up and shutdown without mechanical vibration or current shock.

Three-phase induction motors are widely used in industrial facilities. This controller is designed specifically for their operating characteristics, providing stable and reliable speed control.

A dedicated noise suppression strategy is also implemented for induction motor systems, helping reduce operating noise during continuous operation.

Reliable Protection for Extended Motor Lifetime

The controller integrates comprehensive motor protection functions, including adjustable overload protection thresholds. This helps prevent motor overheating and improves long-term operational reliability.

The system supports both 220V and 380V power supply configurations.

Power ratings include 0.75 kW and 1.5 kW, compatible with 0.75 kW to 1.5 kW three-phase induction motors.

All units undergo full inspection and aging testing before shipment to ensure stable performance.

We operate our own production facility and maintain standardized manufacturing processes with a monthly capacity of 20,000 units across product lines.

Industrial-Grade Fan Control for Harsh Environments

This controller is suitable for factory workshops, warehouses, livestock farms, and other facilities using three-phase induction ceiling fans.

We provide a 3-year warranty for the complete unit and long-term technical support. For international customers, we offer remote debugging, video assistance, and online commissioning support.

Samples are available for evaluation before bulk orders.

This Three-Phase Asynchronous Fan Controller ensures stable operation under harsh conditions, providing smooth motor start-up, reliable speed control, and improved system durability.
