Product Details
The controller is designed for high-efficiency filter fans used in cleanrooms, dust-free rooms, and other environments requiring stringent cleanliness. It employs a brushless DC motor without Hall sensors and utilizes PWM-based output control to achieve high-precision variable-frequency speed regulation of the filter fan. The fan speed can be continuously adjusted within the range of 300–1,500 rpm, with multiple protection features including overvoltage, undervoltage, overcurrent, and excessive PWM module temperature. By assigning unique addresses via the RS-485 communication interface, the system supports zone-based control of up to tens of thousands of FFUs, facilitating flexible network configurations for users.
