UHF induction heating power supply

Frequency Automatic Tracking

ROCHO ultra-high frequency induction heating power supply adopts all-solid-state IGBT inverter control technology, frequency automatic tracking and matching. Even if the working load conditions change, the device will perform continuous real-time output matching and automatic tracking to always meet the set power. The unit provides the max efficiency in the entire heating cycle, ensuring stable and reliable operation.

Precise Brazing Effect

The welding current can be accurately controlled by this ultra-high frequency induction heating power supply. It can accurately locate the welding position, the minimum diameter of welding parts is 0.1mm. After the solder is melted, the heat preservation of the welding can be maintained, so that the solder can fully fill the welding seam, ensure the good welding quality. Different induction heating coils can be customized according to different shapes of metal work pieces.

According to the different specification of work piece, our engineers will design the suitable induction coil to attain optimal welding effect.

All-Round Protection Function

Ultra high frequency induction heating power supply has multiple protection functions including over-current protection, water shortage protection, over-heat protection, over-voltage protection, short-circuit protection, phase failure/loss protection and other alarm functions. It will automatically alarm in case of faults, greatly improving the reliability of the equipment.

The ultra-high frequency induction heating power supply has two operating modes: constant current and constant power. These two mode can be choose according to the heating state of the workpiece, so as to optimize the heating process, achieve rapid heating, and maximize the performance of the equipment.

The ultra-high frequency induction heating power supply has five key parameter, including heating power, thermal power, heating time, thermal time, and cooling time. These parameter can be adjusted independently, so the high frequency machine is suitable for occasions where the heating temperature is controlled more accurately.

The ultra-high frequency induction heating power supply can be equipped with infrared thermometer to realize automatic temperature control and improve heating quality along with temperature control accuracy. It also can be equipped with PLC control system to coordinate with the flow process of the automatic production line.

The ultra-high frequency induction heating power supply adopts microcomputer software intelligent control system, each process has more than 20 programmable temperatures and time periods, ensure the high control accuracy and stable operation of the equipment.

Reliable Design And Strict Testing

Each induction heating power supply has been strictly tested for high power operation in the ROCHO INDUCTION factory, aging and eliminating unstable components, to ensure that each unit has the ability to continuously running for several months.
