1. 12-48V low voltage supply2. Rated current:20A3. Rated :1000W, the bigger voltage, the higher .4. We tested when it works 53V supply, current can reach 30A.It can be used for DIY players to make small parts quenching, annealing and other heat treatment, heating fast, very convenient.5. 24V input and no load current is about 3A. 48V input and no load current is about 6A6. 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. Such as heating under 1cm square small objects, use the 24 v voltage.7. buyer need self-provided and water cooling device8. When made with switch supply, because of the high generally has function of soft start, namely just powered on the output voltage is slowly rising, while if before the voltage up to 12v connected induction heating circuit, will not work and burn MOS tube. So voltage reaches more than 12 v connected induction heating circuit.9. The volume of heated objects cannot be more than 1/10 of the heating coil internal volume (that is, the heating cylinder diameter more than 1/3 heating coil diameter), otherwise it may because of overload and burned circuit or the supply. Although this circuit can tolerate 30A input current, but the insurance for the purpose of work not more than 20A.10. This circuit can do induction heating, or replace copper tube with high frequency transformer, it will be a powerful inverterCondition: NewType: Drive ICcolor:Photo colorMaterial:PCB+MetalPackage Contents:1 x module1 x steel pipeOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
