Featuring three independently adjustable PWM channels, an intuitive LCD display, and robust auto-save functionality, it’s engineered for professionals demanding reliable, real-time control in experimental development, motor control, and MCU applications. ## Description Description: Three-channel PWM is outputted,wide frequency range and the duty ratio can be adjusted independently Frequency is divided into four areas,automatic switching: 1.XXX(No decimal point): 1HZ Stepping Unit,Range:1Hz~999Hz; 2.X.XX(The decimal is in the hundreds place):0.01KHZ Stepping Unit,Range: 1.00Khz~9.99Khz; 3.X.XX(The decimal is in the tens place):0.1KHZ Stepping Unit,Range: 10.0Khz~99.9Khz; 4.X.X.X(The decimal is in the ones place):1KHZ Stepping Unit,Range: 1Khz~150Khz; e.g. ,frequency display:100 represent the pulse of 100Hz ; 1.01 represent the pulse of 1.01KHz; 54.1 represent the pulse of 54.1KHz 1.2.4 represent the pulse of 124Hz The value range of dutyfactor: 0~100%,100% is represented by A0%. All parameters setted up can be automatically saved in case of power cut. Parameter: Has 8 independent keys,used to set the frequency and duty ratio,support short press (increase or decrease a unit) and long press (fast increase or decrease),very simple,set the parameters automatically save,power loss. 3-Way duty ratio button can be pressed at the same time,real-time adjustment, liquid crystal display is the last pressed button duty ratio,real-time is very strong,can be used as a simple several road duty ratio scan. Applications: 1.Used as square wave signal generator to generate square wave signal for experiment development and use 2.Used to generate a square wave signal to control the motor driver; 3.Generating adjustable pulses for MCU use; 4.Generate adjustable pulse, control related circuit (PWM dimming speed and other applications).
