220V AC PWM Power Control Board with Optocoupler Isolation - YYAC-3S Module for Dimming & Speed Regulation (3A/660W)

<ul><li>Enables precise control with PWM output via IO port for dimming, speed, and power adjustments</li><li>Supports controllable load up to 220V 3A or 660W for effective voltage regulation</li><li>Versatile application for dimming, speed, voltage, and temperature control in lamps and household appliances</li><li>Ensures safe operation with original thyristor and isolated input/output optocouplers under weak current</li><li>Provides direct PWM input functionality with 0V low level resulting in 0V output and 5V input yielding 220V output</li></ul>

Brand

Feature:
1. Safe Working: Adopts original thyristor and ensures completed isolated input and output optocouplers, can work safely under weak current.
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.
3. Output Power: Controllable load within the range of 220V 3A or 660W, and the output under certain load can achieve normal voltage regulation.
4. PWM Input: When PWM directly inputs 0V low level, the output is 0V, and when PWM directly inputs 5V, the output is 220V.
5. Application: Connect this control module to lamps or household appliances for dimming, speed, voltage and temperature control.

Specification:
Item Type: PWM Control Module
Product Model: YYAC-3S
Single Chip Microcomputer Voltage: 3.3V~5V available;
Single Chip Microcomputer Frequency: 1HZ~500HZ; 
Single Chip Microcomputer Duty Ratio: 0~100 Percent
PWM: PWM inputs 0V low level directly, the output is 0V; PWM inputs 5V directly, the output is 220V. 
Load Voltage: 220VAC
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). 

Package List:
1 x PWM Control Module
