QXKE PWM Signal Generator LCD Display Frequency Duty Ratio Adjustable Square Wave

Feature: *Signal generator provides electrical signals at a variety of frequencies square wave and output levels.It is used as a signal source or excitation source for testing. *High definition LCD display *1-Channel PWM output. *Support frequency adjustment and duty cycle adjustment; *Wide frequency range and high accuracy. *Support Serial Communication. *Widely used in production practice and technology. Specification: *Work voltage:DC 3.3V-30V *Frequency range:1Hz~150KHz *Frequency accuracy:2% *Duty cycle range:0.00%-100% *Output Current:About 5-30mA *Output amplitude:Same to input voltage *Size:approx. 79*43*27mm *Operating temperature:-20degree Celsius~70degree Celsius Frequency set range: Enter the settings interface when short press any button FREQ+ or FREQ- in the normal running status to select frequency range.Automatically switch frequency range. Pay attention to the position where the decimal point moves when the button is pressed. Display XXX .No decimal point The minimum frequency is 1Hz.The frequency range is 1Hz ~ 999Hz. Display X.XX .The decimal point is the penultimate The minimum frequency is 0.01KHz.The frequency range is 1.00KHz ~ 9.99KHz. Display XX.X .The decimal point is the third last The minimum frequency is 0.1KHz.The frequency range is 10.0KHz ~ 99.9KHz. Display X.X.X .The decimal point is fully lit The minimum frequency is 1KHz.The frequency range is 1KHz ~ 150KHz. For example: Display 100 means PWM output frequency is 100Hz; Display 1.01 means PWM output frequency is 1.01KHz; Display 54.1 means PWM output frequency is 54.1KHz; Display 1.2.4 means PWM output frequency is 124KHz; Duty cycle set range: Enter the settings interface when short press any button DUTY+ or DUTY- in the normal running status to select duty cycle.Automatically switch frequency range. Duty cycle range is 0.00%-100%. Application: *Square wave signal generator generating square wave signal for experimental development; *Used to generate a square wave signal that controls the motor driver; *Generate adjustable pulses for use by the MCU; *Dimmer; *Speed governor Use steps: 1.Connect to power supply; 2.Short or long press button FREQ+ or FREQ- to set frequency; 3.Short or long press button DUTY+ or DUTY- to set duty cycle; 4.Connect to load.
