HALJIA PWM Adjustable Pulse Frequency Duty Cycle Module Square Wave Rectangular Wave Signal Generator XY-LPWM

• LCD can display frequency and duty cycle clearly
• PWM output can set the frequency and duty cycle separately
• Wide frequency range, high precision;
• Working voltage: 3.3 ~ 30V;
• Frequency range: 1Hz ~ 150KHz;

Description: Frequency has four ranges, automatic switching: XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz; X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz; XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz; X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz frequency display: "F101": Setting frequency is 101 HZ (001 ~ 999),"F1.05": Setting frequency is 1.05 KHZ (1.00 ~ 9.99) "F10.5": Setting frequency is 10.5KHZ (10.0 ~ 99.9),"F1.0.5": Setting frequency is 105KHZ (1.0.0 ~ 1.5.0) Duty cycle range: 0 ~ 100%,for example, D050, set the PWM duty cycle is 50%. All set parameters save when power failure. The Module Parameters: Working voltage: 3.3 ~ 30V; Frequency range: 1Hz ~ 150KHz; Frequency accuracy: the accuracy in each range is about 2%; Signal load capacity: the output current can be about 5 ~ 30ma; Output amplitude: PWM amplitude equal to the supply voltage; Ambient temperature: -20 ~ +70 Celsius Material: Metal size: 52 x 32mmx 8mm Colour: Blue The Scope of Application: 1.Used as a square wave signal generator, generate square wave signal for experimental development and use; 2.Used to generate a square wave signal that controls the motor driver; 3.Generate adjustable pulse for MCU use; 4.Generate adjustable pulse, control the relevant circuit Packing List: 1 x rectangular wave signal generator(Two versions, ship randomly.)
