    Parameters:

    • Model: XY-KPWM;

    • Work Voltage:DC 3.3V-30V;

    • Frequency range(Normal mode):1Hz~150KHz;

    • Frequency range(Precise mode):1Hz~15KHz;

    • Frequency accuracy:2%;

    • Duty cycle accuracy:1% at Normal mode;

    • Duty cycle accuracy:0.1% at Precise mode;

    • Duty cycle range:0.00%-100%;

    • Output Current:About 5-30mA;

    • Output amplitude:Same to input voltage;

    • Work Temperature:-40℃~85℃;

    • Work Humidity:0%~95%RH;

    • Size:79*43*37mm;

    Frequency Set Range:

    • There is two work mode so it have two frequency range.

    • Normal mode:Frequency range 1Hz~150KHz.Duty cycle range 000%-100%.Duty cycle accuracy 1%.

    • Precise mode:Frequency range 1Hz~15KHz.Duty cycle range 0.00%-100%.Duty cycle accuracy 0.1%.

    • Enter the settings interface when short press rotary switch in the normal running status to select frequency range.Rotary potentiometer to set frequency value.

    • Keep press rotary switch for 10second to switch Normal mode and Precise mode.

    • Keep press for 5second to locking parameters to protect the parameters from being modified.

    • Pay attention to the position where the decimal point moves when rotary potentiometer..

    • 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 '1.91' means PWM output frequency is 1.91KHz; Display '52.1' means PWM output frequency is 52.1KHz; Display '1.3.4' means PWM output frequency is 134KHz; Duty cycle set range: Short press potentiometer to select set duty cycle and rotary potentiometer to set duty cycle value.

    Use Steps:

    • Connect to power supply;

    • Press rotary switch for 10second to switch Normal mode and Precise mode;

    • Short press rotary switch to set frequency and change value by rotating switch;

    • Press rotary switch for 2second to set duty cycle;

    • Keep press for 5second to lock set parameters;

    • Test;

    • Press button 'ON/OFF' to turn on or off PWM output;

    • Remove power and connect load to use module.

    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.
