SainSmart 1000W ZVS Low voltage induction heating board module/Tesla coil 12V-48V 12-48V low voltage power supply Rated current:20A Rated power:1000W, the bigger voltage, the higher power This circuit can do induction heating, or replace copper tube with high frequency transformer, it will be a powerful inverter The higher voltage, the higher current when heating the same things, the effect is better, but at the same time heating is also higher, therefore the choice of input voltage is based on your need
