Important Usage Notes
- Voltage Sequencing: When using a switching power supply (which has a soft-start function), always allow the output voltage to rise above 12V before connecting the induction heating circuit. Connecting at lower voltages may cause both MOSFETs to conduct simultaneously and damage the board.
- Object Size Limit: The volume of the object being heated must not exceed 1/5 of the coil's internal volume (heated cylinder diameter must be less than 1/3 of the coil diameter). Oversized objects can cause overload and damage to the circuit or power supply.
- Current Monitoring: Although the circuit can momentarily tolerate 20–30A, do not exceed 15A during continuous operation. An ammeter between the power supply and driver board is strongly recommended.
- Cooling Required: For continuous operation, use a fan blowing downward across the board to cool the resonant capacitors and other components. A water-cooling device is recommended for sustained high-power use.
- Voltage Selection: Match your input voltage to your workpiece size. For objects smaller than 1 cm², 24V input is generally sufficient.

Frequently Asked Questions
Q: What input voltage should I use with the ZVS induction heating board?
A: The board accepts 12V–48V DC input. For small objects (under 1 cm²), 24V is typically adequate. Higher voltages deliver more power and faster heating, but also generate more heat in the board itself — so choose your voltage based on your workpiece size and cooling capability. Always ensure voltage is above 12V before connecting the board when using a switching power supply.
Q: Do I need a water-cooling unit to run this induction heating module?
A: A water-cooling device is strongly recommended, especially for sustained high-power operation, as the heating coil assembly generates significant heat during use. At a minimum, use a fan blowing air downward over the board to keep the resonant capacitors and components within safe operating temperatures. The buyer must supply both the power source and the cooling unit separately.
Q: Can this ZVS driver board be used as an inverter?
A: Yes. By replacing the copper induction tube with a high-frequency transformer, this board can be configured as a powerful inverter. This makes it a versatile module for advanced DIY electronics projects beyond standard induction heating applications.
Q: What is the maximum safe continuous current for this board?
A: While the circuit can tolerate momentary current spikes of 20–30A, the recommended maximum for continuous safe operation is 15A. Adding an ammeter in line between your power supply and the board is highly recommended to monitor and prevent overload conditions.
