● 6HP to 12HP: IDU/ODU controller all-in-one designing, cost reducing with wire simplifying; 15-25 HP: separated design, to reduce maintenance costs

● 180°sine wave space vector algorithm drive technology, adaptive torque compensation

● Dual chip design with separate operation for system control and drive control

● Compatible with AC and BLDC fan motors

● Communication way: RS485

● At the same time, it has rich interface resources
