Generator de semnal dreptunghiular reglabil NE555

NE555 pulse frequency, duty cycle adjustable module,square/rectangular wave signal generator,stepping motor driver

Instructions:

Performance:

1.Input Voltage: 5V-15VDC. when power supply is 5V , the output current can be 15MA around;when 12V power supply, the output current can 35MA around;

2.Input current: >=100MA;

3.Output amplitude: 4.2V V-PP to 11.4V V-PP. (Different input voltage, the output amplitude will be different)

4.Maximum output current: >=15MA(5V power supply, V-PP greater than 50%),>=35MA(12V power supply, V-PP greater than 50%)
4.Output with LED indication(low level ,LED will on; high level,LED will off;low frequency, the LED flashes);

5.The output requency range is selectable:

LF file: 1Hz ~ 50HzIF file: 50Hz ~ 1kHz

High-frequency file: 1KHz ~ 10kHz

HF file: 10kHz ~ 200kHz

5.Cycle T=0.7 (RA+2RB) C(RA, RB for 0-10K adjustable);

Low frequency:C=100UF;Intermediate frequency:C=1UF;

M-Hfrequency:C=0.1UF;High frequency:C=0.001UF,

Note:

Before changing the frequency, please power off

Application:

1. Used asa square wave signal generator,offer thesquare wave signal for the use of the experimental development.

2. Used to producedriving stepper motor drives, offer thesquare wave signal.
