Three-Phase Asynchronous Fan Controller

For facilities utilizing traditional fan technology, our RS-ASF2000 series Three-Phase Asynchronous Fan Controller offers a professional-grade upgrade path. This controller is designed for high compatibility, adapting seamlessly to the standard three-phase asynchronous motors found in many existing industrial fans. We have focused on providing a stable and durable unit that can withstand harsh environments while providing the "smooth start" benefits usually reserved for higher-end systems. Our 10 years of engineering experience ensure that this controller is both a cost-effective and highly reliable choice.

The RS-ASF2000 utilizes a refined V/F (Voltage/Frequency) algorithm optimized for fan loads. This ensures that the motor starts smoothly without the high-current spikes that can damage electrical systems. Similar to our PMSM controllers, this asynchronous version features a high-seal design and built-in protection against overloads, overvoltage, and overheating. We understand that in large facilities, fan noise can be a major issue, so we have implemented an electromagnetic noise suppression algorithm to ensure the fans run as quietly as possible. Backed by our 3-year warranty and 100% pre-packing inspection, it is a "set-and-forget" solution for industrial ventilation.
