As a pulse generator, it controls related circuits (PWM dimming, speed adjustment). Package List: 1 x Frequency Generator Note: Please pay attention to electricity safety when using it. How To Use Frequency Display Description: 1. The frequency is divided into 4 ranges and switches automatically. 2. XXX: The minimum unit is 1Hz, and the value range is 1Hz~999Hz. 3. X.XX: The minimum unit is 0.01kHz, and the value range is 1.00kHz~9.99kHz. 4. XX.X: The minimum unit is 0.1kHz; the value range is 10.0kHz~99.9kHz. 5. X.X.X: The minimum unit is 1kHz; the value range is 1kHz~150kHz. 6. For example, the frequency display 100 means 100Hz; display 1.01 means 1.01kHz; display 54.1 means 54.1kHz; display 1.2.4 means 124kHz.
