DC 3.3 -30V 5 -30mA 1Hz -150kHz Adjustable Output PWM Pulse Frequency Meter Duty Cycle Square Wave Signal

Parameter: Working voltage: DC 3.3 -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% Feature: 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 for experimental development As square wave signal for motor driver As adjustable pulse for MCU As pulse , 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 1Hz Package Included: 1 * Multi-function Signal
