Adjustable 2 Channel PWM Generator Wave Signal Pulse Frequency

Detail Adjustable 2 Channel PWM Generator Wave Signal Pulse Frequency

Modul pembangkit gelombang PWM untuk 2 Channel secara independen, artinya kita dapat mengatur duty cycle dan frekuensi tiap channel secara terpisah.

Modul ini mendukung rentang frekuensi 1Hz s/d 150KHz dan duty cycle dari 0 s/d 100%, selain setting via push button yang tersedia, anda juga bisa mengatur modul ini via serial TTL, artinya modul siap dihubungkan ke microcontroller / arduino untuk mengontrol freq dan duty cyclenya, menghasilkan project yang keren

- Frequency accuracy: 2%.
- Output current: 30mA
- Output amplitude: default 5Vp-p (settable)
- Operating temperature range: -30 ~ +70 C
- Dimensi: 4.3 x 2.9 x 0.9 cm

Cara pakai, ada 3 tombol:
1. Press the [ Set ] key momentarily to switch to display four parameter values (FR1 : frequency of PWM1 ; d U1 : duty ratio of PWM1 ; FR2 : frequency of PWM2 ; dU2 : duty ratio of PWM2 ) . The parameter name flashes.
2. Press [ Up ] and [ Down ] directly to modify the current parameter value ( long press to increase or decrease quickly).
3. Two PWM each preset has three kinds of frequency values, the display interface in the frequency, a long press [ SET ] key once to switch, 3 uniform duty cycle frequencies are available . ( XXX: range 1Hz ~ 999Hz ; XX.X : the range of 0.1 Khz ~ 99.9Khz ; XXX : range 1Khz ~ 150 Khz )

Setting PWM Frequency:
1."S1FXXXT":set PWM1 frequency as XXX HZ (001~999)
2."S1FXX.XT":set PWM1 frequency as XX.X KHZ (00.1~99.9)
3."S1F:X.X.X.T":set PWM1 frequency as XXX KHZ (0.0.1.~1.5.0.)
4."S1":PWM1
5."S2":PWM2
6."F":frequency
7."D":duty cycle
8."T":stop sign bit

Setting PWM Duty Cycle
1."S1DXXXT":set PWM1 duty cycle as XXX?(001~100)
2."S2DXXXT":set PWM2 duty cycle as XXX?(001~100)
Setting successfully back:DOWN
Setting unsuccessfully back:FALL
