Safe Working: Adopts original thyristor and ensures completed isolated input and output optocouplers, can work safely under weak current._x000D_ 2. For Control: PWM output through the IO port on single chip microcomputer can adjust the duty ratio and change the 220V AC voltage to achieve the purpose of dimming, speed and power adjustment, etc._x000D_ 3. Output Power: Controllable load within the range of 220V 3A or 660W, and the output under certain load can achieve normal voltage regulation._x000D_ 4. PWM Input: When PWM directly inputs 0V low level, the output is 0V, and when PWM directly inputs 5V, the output is 220V._x000D_ 5. Application: Connect this control module to lamps or household appliances for dimming, speed, voltage and temperature control._x000D_ _x000D_ _x000D_ Specification: _x000D_ _x000D_ Item Type: PWM Control Module_x000D_ Product Model: YYAC-3S_x000D_ Single Chip Microcomputer Voltage: 3.3V~5V available;_x000D_ Single Chip Microcomputer Frequency: 1HZ~500HZ;_x000D_ Single Chip Microcomputer Duty Ratio: 0~100%_x000D_ PWM: PWM inputs 0V low level directly, the output is 0V; PWM inputs 5V directly, the output is 220V._x000D_ Load Voltage: 220VAC_x000D_ Output Power: Can control within 220V 3A, that is, load within 660W (the output needs to carry a certain load to adjust the voltage normally)._x000D_ _x000D_ _x000D_ _x000D_ Package List: _x000D_ _x000D_ 1 x PWM Control Module_x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ 1) We accept Alipay, West Union, TT.All major credit cards are accepted through secure payment processor ESCROW. _x000D_ 2) Payment must be made within 3 days of order. _x000D_ 3) If you can't checkout immediately after auction close, please wait for a few minutes and retry Payments must be completed within 3 days. _x000D_ _x000D_ _x000D_ _x000D_ About shipping _x000D_ 1.
