Product Description
1. Used as a square wave signal generator produces a square wave signal for the experimental development use.
2. Used to generate the square wave signal to drive a stepper motor drive.
3. Produce adjustable pulse for the MCU to use.
4. Generating adjustable pulse to control the associated circuits.
Features:
-Dimensions : 3.5cm *
3.6cm -Main Chip: NE555;
-Input voltage: 5V-15VDC. 5V power supply, the output current can be about 15mA; 12V power supply, the output current can be such 35mA;
-Input current :? 100MA
-Output Amplitude: 4.2V V-PP to 11.4V V-PP (depending on the input voltage, the output amplitude is not the same)
-Maximum output current :? 15mA (5V supply, V-PP more than 50%) ,? 35mA (12V power supply, V-PP is more than 50%)
Advantages:
-Out with LED indicator, no LED output quantity (low, high level LED off relatively low frequency LED flashing);
- Output frequency range optionally continuously adjustable output frequency;
-Low frequency rack: 1 Hz ~ 50 Hz
-If stall: 50 Hz ~ 1 kHz
-In high frequency stall: 1 kHz ~ 10 kHz
-High frequency rack: 10 kHz ~ 200 kHz
-Output duty cycle can fine-tune the duty cycle and the frequency is not adjusted separately, the duty cycle will change the frequency
-Output frequency is adjustable;
-Cycle T = 0.7 * (Ra + 2 * Rb) * C
-Ra, Rb: 0-10 K adjustable;
-LF gear C = 0.001uF;
-If file C = 0.1uF;
-In high frequency file C = 1 uF;
- High frequency transmission C = 100uF, buyers of frequency signals can have their own calculations.
Note: The output duty cycle can fine tune the duty cycle and the frequency is not adjustable separately adjust the duty cycle will change the frequency
