This is a new version that optimizes PCB wiring and adds a voltage selection switch. The overall size is reduced, making it more convenient and suitable for smaller chassis installation. Solved many buyers' troubles. Compared to previous versions, this PCB layout is more convenient to use.
Input voltage: AC 110V or 220V (Optional)You can also change the voltage yourself. On the PCB, we have set a voltage switch, which allows you to easily change the voltage.
