915 Generation Digital Display PWM Pulse Square Wave Rectangular Signal

Detailed Information About The Product:

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;
Set PWM frequency:‘F101’:Set frequency is 101Hz.‘101’ can by replace by 001~999;‘F1.05’:Set frequency is 1.05KHz.‘1.05’ can by replace by 1.00~9.99;‘F10.5’:Set frequency is 10.5KHz.‘10.5’ can by replace by 10.0~99.9;‘F1.0.5’:Set frequency is 105KHz.‘1.0.5’ can by replace by 1.0.0~1.5.0;
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.
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.Automaticallyswitch frequency range.Duty cycle range is 0.00%-100%.
Use steps:Connect to power supply;Short or long press button ‘FREQ+’ or ‘FREQ-’ to set frequency;Short or long press button ‘DUTY+’ or ‘DUTY-’ to set duty cycle;Connect to load.UART communication and parameter settingsThe system supports UART data upload and parameter setting functions (TTL level);
UART: 9600, 8, 1
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.
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;
