The drive module is made of 16mm double-layer fiberglass board. This induction heating system uses a low-voltage power supply of 12-30V It features fast and convenient heating, low heat generation, and high efficiency The resistors used are five-ring precision resistors—these have low error rates and ensure more stable operation Additional tin has been added to the bottom of the board, allowing it to be used effectively for induction heating, Manufacturer: Santiway
