Product Definition

What Is a Medium-Frequency Power Supply in Parallel?

A medium-frequency power supply in parallel is an industrial induction power system that converts incoming AC power into adjustable medium-frequency current and energizes an induction load through a parallel-resonant circuit.

The KGPS-BL series is used as the electrical power source for industrial induction melting furnaces and heating equipment. The system converts incoming power into adjustable medium-frequency current and delivers it to a parallel-resonant induction load. Power rating, output frequency, incoming voltage and supporting components can be configured according to the furnace capacity, metal type and production requirements.
The control board of the parallel medium-frequency power cabinet uses an advanced integrated circuit as its control core, providing strong control capability and a high level of integration. The connection between the control board and the main circuit is simple and reliable, while the integrated control design supports stable operation, protection and system regulation.

ADVANTAGES

Product Advantages of Medium-Frequency Power Supply in Parallel

The control board of the equipment adopts advanced integrated circuit as the control core, which has strong control ability and high integration degree. The connection between the whole control board and the main circuit is simple and reliable, and has perfect control function.
This device is equipped with a complete multi-channel protection system including overcurrent, overvoltage, current limiting, and voltage limiting. Once a circuit fault occurs, the protection system will act within a short time, reliably protecting valuable components such as thyristors and capacitors from damage, preventing unnecessary losses. Each control system has an interlock function to effectively prevent incorrect operation.
This control system adopts zero-voltage soft start and slow start functions, and uses an advanced dual closed-loop regulation system. In actual operation, it can start 100% reliably and without impact. In real operation, even under conditions of large load changes, the equipment can operate steadily and reliably.
