The following is a description of the IH principles behing our
induction hardening and the features of our power unit.

[IH (Induction Heating)]
① Current flows through the coil.
② A magnetic field is generated.
③ Eddy currents are generated on the workpiece surface.
④ The workpiece heats itself via Joule heating.

[Fuji Denshi Power Unit]
・The photo shows our high frequency power unit.
・One unit can be used to generate multiple frequencies,
eliminating the need for multiple units for different hardening specifications.
・When replacing our vacuum tube converters with transistorized converter,
in general, the same coils can be used.

[Eco-friendly Energy Source]
・Our converter achieves a converter efficiency of 95%,
the highest in the industry.
・High converter efficiency reduces power consumption loss
and thereby saves energy required for quenching as well.

・Electrical costs reduced more than half compared to vacuum tube converters.
