DollaTek PWM signal generator pulse frequency duty cycle adjustment module adjustable square wave rectangular wave signal source

About this item

• •Description:
• •3-way PWM output, wide frequency range, duty cycle can be adjusted independently and in real time.
• •Frequency is divided into four ranges, automatic switching:
• •1. XXX (no decimal point): the smallest unit is 1Hz, the range of values is 1Hz ~ 999Hz;
• •2. The smallest unit of X.XX (decimal point in 100 bits) is 0.01 Khz, ranging from 1.00 Khz to 9.99 Khz.
• •3. XX.X (decimal point in ten places): the smallest unit is 0.1Khz; the range of values is 10.0KHz~99.9KHz.
• •4. X.X.X (decimal point in 10 and 100 bits): the smallest unit is 1Khz; the range of values is 1KHz~150KHz
• •Features:
• •Square wave signal used to control motor driver;
• •Generate adjustable pulses for MCU use.
• •Generate adjustable pulses and control related circuits (PWM dimming and speed regulating applications).
• •The module has 8 independent keys to set the frequency and duty cycle. It supports short press (increase or decrease a unit) and long press (increase or decrease quickly). It is very simple. After setting parameters, it can save automatically without losing power.
• •3-way duty cycle button can be pressed at the same time, real-time adjustment, LCD display is the last pressed button duty cycle, real-time performance is very strong, can be used as a simple scan of several ways duty cycle.
