1. Completely solve the hot bed power is too large and the load current issue
2. Under the premise of normal cooling, it work stable under I(Max)=25A, the current must not exceed 25A while the process is working
3. If you need anything greater or equal to 15A this module is a must! For example, if your total power usage is 240W and you have 12V power supply, then it means at least 20A is needed (20X12=240W).
4. As ChiTu controller board is only capable of 15A this setting will not work. To make it work, you need this extra power module.
