PWM output, you can set the frequency, duty cycle; Normal mode: Frequency range:1Hz~150KHz Duty:000~100%, duty-free step 1%; Fine mode: Frequency range:1Hz~15khz Duty:00.0~100%, duty-free step 0.1%;
Frequency is divided into four ranges, automatic switching: 1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz; 2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz; 3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz 4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz
frequency display: 100 indicates PWM output 100Hz pulse; 1.01 indicates PWM output 1.01K pulse; 54.1 indicates that the PWM output has a pulse of 54.1 kHz; 1.2.4 indicates that the PWM output is 124 kHz pulse; Duty cycle range: 0 ~ 100%; All set parameters, power-down automatically saved.
Second, the parameter settings This product through the Rotary Encoder to adjust the frequency and duty cycle, can be determined according to the rotation speed to achieve rapid adjustment, the default adjustment duty cycle, short press adjust frequency, long press 2 seconds lock, long press 5 seconds switch mode (normal mode/fine mode), simple operation, set the parameters of automatic saving, no loss of power.
Third, the module parameters: 1. Working voltage: 3.3 ~ 30V; 2. Frequency range: Normal Mode:1Hz ~ 150KHz Fine Mode:1Hz~15KHz 3. Frequency accuracy: the accuracy in each range is about 2%; 4. Signal load capacity: the output current can be about 5 ~ 30ma; 5. Output amplitude: PWM amplitude equal to the supply voltage; 6. Ambient temperature: -20 ~ +70 ℃.
