PULS/FREQ GENERATOR

NE555 Pulse Frequency Duty Cycle Adjustable Module

Performance:

1.Input Voltage: 5V-15VDC. when power supply is 5V , the output current can be 15MA aroundwhen 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 offlow frequency, the LED flashes)

5.The output requency range is selectable:

LF file: 1Hz č 50Hz IF file: 50Hz č 1kHz

High-frequency file: 1KHz č 10kHz

HF file: 10kHz č 200kHz

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

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

M-H frequency: C=0.1UF High frequency: C=0.001UF,

Note:

Before changing the frequency, please power off



Application:

1. Used as a square wave signal generator, offer the square wave signal for the use of the experimental development.

2. Used to produce driving stepper motor drives, offer the square wave signal.

3. Adjustable pulse for the use of MCU.

4. Generate adjustable pulse control circuit.
