This circuit configuration minimizes the current decay time by reducing the internal impedance of the magnetizer to the utmost limit and efficiently outputting the magnetizing current. When using general magnetizers to perform continuous magnetization, incomplete magnetization may occur due to a decrease in magnetizing current brought about by the damage to magnetizing yoke caused by its rising temperature leading to caused by a rise in winding resistance. The low impedance type (Type L) can suppress heat generation of the magnetizing yoke to less than 1/5 of the conventional type. An ultra-low impedance type (Type R) can also be produced with dedicated settings to match the operating load.
Can be set for SX, SR, SA, and SCB type magnetizers
