Treedix 5-12V ZVS Induction Power Supply
Treedix offers a ZVS-based low-voltage induction heating power source with an included heating coil. It supports DC input in the 5V–12V range and is designed for compact heating tasks. A key note is the coil sizing guidance: the object to be heated should be about one-third to one-half the inner coil diameter, and not exceed two-thirds of that diameter. The heating coil can be soldered onto the PCB to simplify assembly, making it suitable for quick prototyping and hobbyist projects.
Chazcool Mini ZVS Low Voltage Induction Heater
The Chazcool kit includes a mini ZVS induction heater board with a heating coil that can be soldered to the PCB. It operates on DC 5V–12V, with the stated voltage range reflecting operating conditions rather than no-load voltage. Proper setup involves verifying that all components are correctly soldered and the power cord connected correctly before powering the circuit. This unit is designed for small-scale heating tasks and educational experimentation.
TEAMWILL 1000W ZVS Induction Board
TEAMWILL’s 1000W ZVS board targets higher-power induction heating. Built on a robust double-layer fiberglass board with a large inductance coil and stable 5-band resistors, it offers dependable performance when paired with an appropriate power supply. The kit is popular among hobbyists for DIY hardening, annealing, and small-scale metal heating, and it can be used with a graphite crucible for melting metals like gold, silver, copper, and aluminum. Users should ensure the supply and wiring match the stated ratings to achieve stable operation.
Yuecoom 1000W ZVS Induction Module
Yuecoom’s induction heater kit emphasizes stable heat with a large heatsink and a design focused on good heat dissipation. It uses a 36V power supply as a baseline, offering a robust platform for higher-power heating applications. The kit features a large heat sink and a design that supports stable operation under sustained heating tasks. It is well-suited for hobbyists performing heat treatments, annealing, or small-scale metal processing where reliable heat control is essential.
Denpetec Induction Heater 2500W ZVS
Denpetec delivers a high-power ZVS induction heater module rated up to 2500W with a recommended input range of 12–48V (favoring higher voltages for peak performance). The design emphasizes a copper-rich output and a robust copper-clad pathway, aiding current delivery and heat dissipation. A copper-ring assembly provides flexible connection options for various heating setups, making this model suitable for serious hobbyists and small workshops requiring substantial heating capacity.
Buying Guide
- Voltage range and power: Choose a unit whose voltage range matches your supply and intended heating tasks. Higher wattage enables faster heating but demands better cooling and a suitable power source.
- Coil and object sizing: Coil inner diameter and the guidance that the heated object should be about one-third to one-half of the coil diameter (not exceeding two-thirds) affects heat efficiency and uniformity.
- Coil integration: Some kits solder the coil directly to the PCB, simplifying assembly but reducing flexibility. If you plan to swap coils for different tasks, prioritize modular coil designs.
- Thermal management: Heatsinks, fans, and board layout influence stability under continuous operation. Look for designs that emphasize heat dissipation for long sessions.
- Application scope: For small parts and educational experiments, low-voltage, compact modules are convenient. For metalworking or hobby-grade melting and heat treatment, higher-power modules are more appropriate.
- Safety and setup: Verify correct wiring, proper insulation, and the recommended power supply. Start with low-power tests to avoid coil overheating and unintended arcing.
- Accessories compatibility: Some kits include a heating coil; others require a separate coil. Consider whether you need additional coils or alternative coil shapes for your work piece.
- Build quality and documentation: Review product manuals for installation steps, wiring diagrams, and safety notes. Clear documentation reduces setup errors and improves reliability.
