Specificații în limba engleză:
HW-752 3 Channel PWM Signal Generator Board Module 1Hz 150KHz Pulse Frequency Duty Cycle Adjustable with LCD Display 3.3 30V
Feature:
1. With 3 PWM outputs, adjustable frequency, the same frequency output of 3 channels, independent adjustment of duty cycle, suitable for most occasions;
2. LCD display frequency and duty cycle, very clear and easy to adjust;
3. Wide frequency range and high precision;
4. Serial communication.
Specification:
Working voltage: 3.3 30V
Frequency range: 1Hz 150KHz
Frequency accuracy: The accuracy in each range is about 2%
Signal load capacity: the output current can be around 3.3 30ma
Output amplitude: PWM amplitude is equal to the supply voltage
Ambient temperature: -20 +70
Product size: 55*38*10mm
Product weight: 15g
1.Output of three-channel PWM at the same time, Adjustable frequency, 3-channel frequency output consistent, duty ratio can be independently adjusted, suitable for most occasions
2.Lcd can display frequency and duty datio,Easy to oprate;
3.Wide frequency range, high precision;
4.Support Serial operation
Module description:
Three-channel PWM is outputted,wide frequency range and the duty ratio can be adjusted independently;
Frequency is divided into four areas, automatic switching
1.XXX(No decimal point): 1HZ Stepping Unit, Range: 1Hz 999Hz;
2.X.XX(The decimal is in the hundreds place):0.01KHZ Stepping Unit, Range: 1.00Khz 9.99Khz;
3.X.XX(The decimal is in the tens place):0.1KHZ Stepping Unit, Range: 10.0Khz 99.9Khz;
4.X.X.X(The decimal is in the ones place): 1KHZ Stepping Unit, Range: 1Khz 150Khz;
e.g. ,frequency display:100 represent the pulse of 100Hz ;
1.01 represent the pulse of 1.01KHz;
54.1 represent the pulse of 54.1KHz
1.2.4 represent the pulse of 124Hz
The value range of duty factor: 0 100%,100% is represented by A0%.
All parameters setted up can be automatically saved in case of power cut.
Parameter settings:
Module has 8 independent keys, used to set the frequency and duty ratio, support short press (increase or decrease a unit) and long press (fast increase or decrease), very simple, set the parameters automatically save, power loss.
3-Way duty ratio button can be pressed at the same time, real-time adjustment, liquid crystal display is the last pressed button duty ratio, real-time is very strong, can be used as a simple several road duty ratio scan.
