Descriptions: 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.
