ITEM NAME:Adjustable Digital Display Current Signal Generator Module 3.3~30V XY-PWM1 Neu Descriptio n Description: 1. Dual mode, duty cycle stepping 0.1% in fine mode; 2. LCD liquid crystal display frequency and duty cycle, very clear, using code potentiometer adjustment, very convenient; PWM output can be set separately frequency and duty cycle; 3. With locking function to prevent misoperation; 4. Can set the upper and lower limits of the duty cycle; KPWM with switch, can turn the PWM output on and off with one button; 4. Wide frequency range and high precision; 5. Serial communication First, the module description PWM output, you can set the frequency and duty cycle separately; Normal mode: Frequency range 1HZ~150KHZ Duty cycle 000~100%, duty cycle step 1% Fine mode: Frequency range 1HZ~15KHZ Duty cycle 00.0~100%, duty cycle step 0.1% The frequency is divided into four ranges and is automatically switched: 1.XXX (no decimal point): The minimum unit is 1 Hz, and the value ranges from 1 Hz to 999 Hz. 2.X.XX (the decimal point is in the hundredth place) The minimum unit is 0.01Khz, and the value range is 1.00Khz~9.99Khz; 3.XX.X (decimal point is ten): the minimum unit is 0.1Khz; the value range is 10.0KHz~99.9KHz 4.X.X.X (decimal point in ten and hundred): the minimum unit is 1Khz; the value range is 1KHz~150KHz E.g. Frequency display: 100 means PWM output 100Hz pulse; 1.01 indicates that the PWM outputs a pulse of 1.01K; 54.1 indicates that the PWM outputs a pulse of 54.1 kHz; 1.2.4 indicates that the PWM output is a pulse of 124KHz; The duty ratio ranges from 0 to 100%. All setting parameters are saved after power down. Second, the parameter settings This product adjusts the frequency and duty ratio by rotating the potentiometer. It can realize rapid adjustment according to the rotation speed. The default adjustment of duty ratio, short press of the adjustment frequency, long press for 2 seconds to lock, long press for 5 seconds to switch mode (normal mode / Fine .Signal load capacity: the output current can be around 5~30ma;. Can set the upper and lower limits of the duty cycle; KPWM with switch, can turn the PWM output on and off with one button;. 1.2.4 indicates that the PWM output is a pulse of 124KHz;.
