DROK Frequency Generator Pack of 2, DC 3.3V-30V 5-30mA 1Hz-150kHz Adjustable Output PWM Pulse Duty Cycle Square Wave Function Signal Generator Module

DROK Function Generator Parameter: Working voltage: DC 3.3V-30V Frequency range: normal mode 1Hz-150kHz; accurate mode 1Hz-15kHz Frequency accuracy: 2% in each range Signal load capacity: output current about 5-30mA Output amplitude: PWM amplitude equals to input voltage value Working temperature: -20℃~+70℃ Duty cycle range: 0-100% Features: With 2 modes. Operated by code potentiometer. With lock function to avoid misoperation. Duty cycle upper and lower bounds is adjustable. 2 Modes: Normal mode: Frequency range 1Hz-150kHz, duty cycle 000-100%, duty cycle step 1% Accurate mode: Frequency range 1Hz-15kHz, duty cycle 00.0-100%, duty cycle step 0.1% Application: As square wave signal generator for experimental development; As square wave signal generator for motor driver; As adjustable pulse generator for MCU; As pulse generator, control related circuits (PWM dimming, speed regulating). Frequency Display Instruction: The frequency is divided into 4 ranges and switched automatically. 1. XXX: minimum unit 1Hz, value range 1Hz~999Hz. 2. X.XX: minimum unit 0.01kHz, value range 1.00kHz~9.99kHz. 3. XX.X: minimum unit 0.1kHz; value range 10.0kHz~99.9kHz. 4. X.X.X: minimum unit 1kHz; value range 1kHz~150kHz. e.g. Frequency displays 100 represents 100Hz; displays 1.01 represents 1.01kHz; displays 54.1 represents 54.1kHz; displays 1.2.4 represents 124kHz Package Included: 2x Function Signal Generator
