1.Description:

Thyristor module is completely isolated from the input and output optocouplers, and can be used safely when the weak current is completely isolated.

It uses the I/O port output from MCU to adjust the duty cycle to change the 220V AC voltage to achieve the dimming speed regulation power, etc.

2.Features:

1>.Multi-application mode;

2>.Optocoupler isolated output;

3>.Support PWM control;

4>.Low power consumption;

5>.Small size;

3>.Control Voltage:DC 3.3V-5.0V

4>.Load Working Voltage:AC 220V

5>.Load Output:AC 220V

6>.Load Current:3A(Max)

7>.PWM Control Frequency:1Hz~500Hz

8>.Duty Cycle:0~100%

9>.Working Temperature range:-40℃~85℃

10>.Working Humidity range:0%-95%RH

4.Function:

1>.Light modulator:Change the voltage of the lamp to adjust the brightness of the lamp by adjusting the PWM.

2>.Regulator:Change the duty cycle to change the voltage.

3>.Thermostats:Change the temperature by voltage control heater or cooler.

4>.Motor speed regulation:Change voltage for motor.

5>.Example:Module will output 0V is input 0V low level signal from PWM;Module will output 220V is input 5V high level signal from PWM.

5.Key core code:

Such as controlling the brightness of the lamp:

While(1)

{

PWM++;

If(PWM==PWM_set) P1^0=0; //The larger the PWM_set, the brighter the light

If( PWM>=10) {P1^0=1;PWM=0; }

}

6.Using Steps:

1>.Write the complete code according to MCU such as Arduino,Raspberry Pi,AVR,ARM,STM32 and so no.

2>.Connect control power supply 3.3V~5V for module.

3>.Connect Load Working Voltage at ‘N’ and ‘L’.

4>.Connect Load such as lamp or motor.

5>.Connect MCU to get PWM signal.

6>.Turn ON power for module and use module.

7.Note:

1>.Please connect load before PWM adjust;

2>.It is also possible to use a signal generator to control the module, but it must meet the frequency requirements;

3>.Wire cannot be reversed.Otherwise the module will be damaged.

8.Application:

1>.Toy

2>.Intelligent robot control

3>.Smart car

4>.Mechanical control

5>.Adjust the brightness of the lamp

6>.Control motor speed

7>.Adjust the voltage range
