2500W Induction Heater High Frequency Low Voltage Induction Heating Module 12V‑48V Flyback Drive Heater with Brass Ring Item Type: Induction Heater Material: PCB, Brass Power Requirements: Below 12V, greater than or equal to 10A Above 15V, greater than or equal to 20A Fan: With a silent fan Maximum Power: 2500W Maximum Current: 50A 1. The heating power is very high, except for the boards and components being very hot, the heating capacity of brass pipes is very high. Buyers can prepare a separate water cooling system by purchasing a small water pump and a 2 meter rubber hose with an inner diameter of 4mm. 3. When heating metal objects, please do not heat too much metal, otherwise it may cause power overload. Please add a 35A fuse or ammeter, and the air switch will be better. (Packaging not included) 4. Although this drive board can withstand a current of over 40A, it is recommended not to exceed 48V 35A to avoid accidents and damage. 7. If encountering MOS tube heating, the first thing to consider is whether the output power meets the requirements. 8. Do not empty the board, otherwise it will emit high noise frequency and burn out the MOS transistor.
