1V2 Medium-Frequency Power Supply in Series

It can be connected to two smelting furnaces, which improves production efficiency.

Medium-Frequency Power Supply in Parallel

The structure is simple, safe and stable, and it is easy to operate and maintain.

WORKS

How Induction Heating Power Supply Works

1V1 Medium-Frequency Power Supply in Series (One-to-One)

The 1V1 model adopts a series resonant inverter circuit. A reactor charges the capacitor to provide a stable DC link voltage for the inverter. The capacitor also helps block higher-order harmonics from feeding back into the grid, enabling a power factor above 95% and reducing harmonic pollution.

1V2 Medium-Frequency Power Supply in Series (One-to-Two)

The 1V2 model uses the same series resonant inverter technology, but one power supply can drive two furnaces simultaneously. Output power can be flexibly distributed between furnaces—for example, one furnace can run at high power for rapid melting while the other operates at lower power for temperature holding—supporting continuous production and improved overall efficiency.

Medium-Frequency Power Supply in Parallel

The parallel model features advanced IC-based control with zero-voltage soft start and dual closed-loop regulation. It provides stable output and high reliability, delivering efficiency ≥95% and cosφ ≥.92 under all load conditions.

Overall Advantage

All models feature constant power output and multiple protection systems, ensuring fast melting, energy saving, and safe, reliable operation across various industrial applications.

SELECT

How to Select the Right Induction Heating Power Supply

1V1 Medium-Frequency Power Supply in Series (One-to-One)

Recommended for applications requiring high power factor (>95%), low harmonics, and flexible power distribution. It is applicable to regions where there are clear requirements and reward-penalty rules for the power factor of industrial electricity consumption.

1V2 Medium-Frequency Power Supply in Series (One-to-Two)

Best choice when you need one power supply to drive two or more furnaces simultaneously with free power allocation between melting and insulation. Suitable for continuous casting and high-efficiency production lines.

Medium-Frequency Power Supply in Parallel

Suitable for simple single-furnace operation or applications needing strong control stability, reliable soft start, and wide load adaptability. Preferred when ease of maintenance and stable performance under varying loads are priorities.
