Feature: 1. High Performance Speed Control: Adopts PWM (Pulse Width Modulation) technology to realize stepless speed regulation, which makes the motor speed adjustment smoother, faster response and more efficient. 2. Wide Compatibility: This PWM speed controller is designed for many specifications of brushless motors, including for 3650 3525 2418 2430 and other series, which ensures wide applicability in different application scenarios. 3. Flexible Frequency Switching: Motor PWM speed controller provides adjustable PWM frequency options, preset to 20kHz, or manually adjustable to 2kHz to adapt to the needs of different motor characteristics and application scenarios. 4. Stable Load Range: This motor speed regulator supports direct current 6‑30V operating voltage, which provides great voltage adaptability and stability to ensure reliable operating under different power conditions. 5. Forward And Reverse Operating: The built in forward and reverse switching function of the PWM speed controller module makes the motor drive more flexible and suitable for working environments that require direction change.
