DC 530V Micro USB 5V Power Independent PWM Generator

Product Description 1.Frequency is divided into three ranges: 1)XXX (no decimal point):the smallest unit is 1Hz, the range 1Hz~999Hz; 2)XX.X (decimal point in ten):The minimum unit is 0.1Khz;the range of 0.1KHz~99.9KHz 3) X.X.X.(there are three decimal point):the smallest unit is 1Khz:the range 1KHz~150KHz 2.Frequency display example: 1)"100" indicates that the PWM output pulse of 100HZ; 2) "54.1"indicates that the PWM output pulse of 54.1KHz 3)"1.2.4." Indicates that the PWM pulse output 124KHz Duty Cycle in the range:0 to 100; Three frequencies duty cycle is the same,all the non-volatile. 3.Highlights: 1) Two independent PWM generators can set the frequency,duty cycle; 2) The wide frequency range,high accuracy; 3) Can serial communication. Product 1)Working voltage:5--30V,support micro USB 5.0V power supply ; 2) Frequency range:1Hz~150KHz 3)The frequency accuracy:±2% 4)Output Current:< 30mA 5)Output amplitude:Default 5vp-p (settable) 6)Operating temperature range:-30~+70°. Parameter Settings: Module has three ons [Set], [Up], [Down]; 1): Pre [Set] key to switch the display four (FR1: PWM1 frequency; du1:PWM1 duty cycle: FR2: frequency of PWM2;dU2:PWM2 duty cucle),before the handover , there will be corresponding parameter name flash. 2)Pre [Up], [Down] keys to modify the current parameter value(long pre can quickly add or subtract fast). 3)Two PWM each have three preset frequency, the frequency display interface, long pre [SET] key to switch between three types of frequencies,three kinds of frequency duty cycle is the same value.(XXX:range 1Hz~999Hz;XX.X: range 0.1Khz;X.X.X.:range 1Khz~150Khz,). Serial Control Baud rate:9600 bps. Data bits:8. Stop bits:1. Parity bit:none. Flow control:none. 1,set the PWM frequency. "S1FXXXT":setting PWM1 frequency of XXX HZ(001~ 999). "SIFXX.XT":set the frequency of PWM1 XX.X KHZ(00.1 ~99.9) "S1F:X.X.X.T":setting PWM1 frequency of XXX KHZ(0.0.1~1.5.0.). 'S1':PWM1 'S2':PWM2 'F' : Frequency 'D' :Duty Cycle. 'T'is the end flag. Set the PWM duty cycle "S1DXXXT" : setting PWM1 duty cycle XXX ; ( 001~100). "S2DXXXT" : set PWM2 duty cycle XXX;(001~100). Setting succeful return:DOWN; Setting failback:FALL.

Scope Of Application As square wave signaenerator which generates a square wave signal; to provide a signal to the stepping motor driver; Adjustable pulse generation for use; produce variable pulse signal, the control-related circuit ( PWM dimming,speed).
