VCC: positive power supply (24V10A and above, 48V50A do not use lead-acid batteries) GND: negative power supply Fan: 48V after a single 24V in series Drive output: OUT put_A, OUT put_B Coil production: 4-5MM for 24-48V ( winding the coil, you can use a sallow tube to cover the copper tube to prevent short circuit during heating). The more power the less Notice: 1. It is not possible to energize without connecting the coil or the high-voltage package. 2. It is best to connect an air switch between the power supply and ZVS to prevent the power supply from being by excessive current when the power supply is turned on. 3. For the first use, connect the coil and power on for 5-10 seconds to check whether the heat sink is hot (if the power is too , the heat sink will be seriously heated when the power supply is overloaded). If it is too hot, increase the number of turns. 4. Use (above 1000W) to cool the copper pipe with water.
