Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module LCD - Tiga Channel

PWM output, you can set the frequency, duty cycle; Frequency is divided into 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 - e.g. frequency display: 100 indicates PWM output 100Hz pulse; 1.01 indicates PWM output 1.01K pulse; 54.1 indicates that the PWM output has a pulse of 54.1 kHz; 1.2.4 indicates that the PWM output is 124 kHz pulse; - Duty cycle range: 0 ~ 100%; - All set parameters, power-down automatically saved. Feature: - LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle; - Wide frequency range, high precision; - Serial communication, TTL level Parameter Settings: The module has four independent keys, used to set the frequency and duty cycle, support touch (increase or decrease a unit) and long press (fast increase or decrease), set the parameters automatically save, power down Not lost. 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 '\. Application: - Used as a square wave signal generator, generate square wave signal for experimental development and use; - Used to generate a square wave signal that controls the motor driver; - generate adjustable pulse for MCU use; - generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications). - serial control (single-chip TTL level communication) -- deskripsi berlanjut di gambar 5 --
