1.Description:

• XY-KPWM signal generator is a device that 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.Widely used in production practice and technology.

• PWM frequency supports 2 modes:normal mode & accurate mode.Regular mode with 1% duty cycle steps.Precision mode with 0.1% duty cycle steps.

• With lock function; PWM output can set frequency & duty cycle separately; duty cycle upper and lower bounds adjustable; support serial communication; all data auto-saved after setting.

• Square wave signal generator, generating square wave signal for experimental development, generating square wave signal that controls the motor driver, and generating adjustable pulses for MCU Dimmer; Dimmer; Speed governor, and so on.

• There is no output voltage control. The output voltage is the same as the input voltage. That can be easily changed by adding a simple potentiometer.

2.Features:

• With outer casing
• LCD high definition display
• Support UART
• Support frequency adjustment
• Support duty cycle adjustment
• High precision detection
• Support power-down memory function
• 1-Channel PWM output
• Dual Work Mode
• Knob supports lock function to avoid misoperation
• Support enable output

4.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;

5.Duty cycle set range:

Short press potentiometer to select set duty cycle and rotary potentiometer to set duty cycle value.

6.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.

7.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;
