Module Features: 1. Dual-mode operation: Normal mode and High-Precision mode. - Lock function prevents accidental operation. 2. Clear LCD display showing frequency and duty cycle. - Encoder potentiometer for intuitive, precise adjustment. - Independent setting of PWM output frequency and duty cycle. 3. PWM output with separately adjustable frequency and duty ratio. 4. Adjustable upper and lower limits for duty cycle. - One-key ON/OFF control for PWM output. 5. Wide frequency range with high stability. - Supports serial communication. Model: XY- Normal Mode: - Frequency range: 1 Hz – 150 kHz - Duty cycle range: 1% – 99% High-Precision Mode: - Frequency range: 1 Hz – 15 kHz - Duty cycle resolution: 0.0–0.1% Frequency Display Format: - 1 Hz – 999 Hz: Unit = 1 Hz (e.g., “100” = 100 Hz) - 1.00 kHz – 9.99 kHz: Unit = 0.01 kHz (e.g., “54.1” = 54.1 kHz) - 10.0 kHz – 99.9 kHz: Unit = 0.1 kHz - 100 kHz – 150 kHz: Unit = 1 kHz (e.g., “124” = 124 kHz) All settings are saved automatically when powered off.
