Product Details
PWM Pulse Frequency module work voltage range is DC 3.3V-30V; the frequency range is 1Hz-150kHz/1Hz-15kHz; the output current is 5-30mA.
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.

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:
1>.Connect to power supply;
2>.Press rotary switch for 10second to switch Normal mode and Precise mode;
3>.Short press rotary switch to set frequency and change value by rotating switch;
4>.Press rotary switch for 2second to set duty cycle;
5>.Keep press for 5second to lock set parameters;
6>.Test;
