Product information
Controller Pulse Frequency Duty Cycle:
Specifications:
Main Chip: NE555
Input Voltage: 5-15V DC
Output Amplitude: 4.2V V-PP to 11.4V V-PP
Maximum Output Current: >=15MA (when 5V power supply, V-PP greater than 50%),>=35MA (when 12V power supply, V-PP greater than 50%) Output with LED indication (low level ,LED will on; high level, LED will off; low frequency, the LED flashes);
Size: Approx. 31 x 24cm
1. Output with LED indication, there is no output straightforward (low LED volume,
high LED off frequency is relatively low, the LED flashes);
2. Output level selectable frequency range, the output frequency is more continuously adjustable;
LF file: 1Hz ~ 50Hz
IF file: 50Hz ~ 1kHz
High-frequency file: 1KHz ~ 10kHz
HF file: 10kHz ~ 200kHz
3. Output duty cycle can fine-tune, duty cycle and frequency is not separately
adjustable, adjusting the duty cycle will change the frequency
4. Output frequency is adjustable;
Period T = 0.7 (RA +2 RB) C
RA, RB is 0-10K adjustable;
Low profile when C = 0.001UF;
IF stalls C = 0.1UF;
High-frequency file C = 1UF;
HF stalls C = 100UF, so the frequency of the waveform buyers can own calculations.
Uses:
1. Used as a square wave signal generator used for experimental development.
2. To drive a stepper motor for generating a square wave drive signal.
3. Adjustable pulse generation for use by MCU.
4. Adjustable pulse generation, control circuitry associated.
