13>.Work Humidity:0%~95%RH;

14>.Size:79*43*37mm;

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 pre rotary switch in the normal running status to select frequency range.Rotary potentiometer to set frequency value.

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

Keep pre 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 pre potentiometer to select set duty cycle and rotary potentiometer to set duty cycle value.

6.Use steps:

1>.Connect to power supply;

2>.Pre rotary switch for 10second to switch Normal mode and Precise mode;

3>.Short pre rotary switch to set frequency and change value by rotating switch;

4>.Pre rotary switch for 2second to set duty cycle;

5>.Keep pre for 5second to lock set parameters;

6>.Test;

7>.Pre on 'ON/OFF' to turn on or off PWM output;

8>.Remove power and connect load to use module.

7.Application:

1>.Square wave signal , generating square wave signal for experimental development;

2>.Used to generate a square wave signal that controls the motor driver;

3>.Generate adjustable pulses for use by the MCU;

4>.Dimmer
