Different choices of magnetic materials (Silicon steel sheets, ferrite material or amorphous core) are available to match the frequencies of different application. Due to the excellent foil winding structure, output AC Reactor is characterized by small DC resistance, strong ability to withstand short circuit and strong short-time overload capability. This reactor is made of H Class insulation materials which gives reliable performance even in harsh operating conditions. Designed with low magnetic flux density, the reactor is of high linearity and powerful overload capacity. Moreover, combined with VPI process, the reactor noise is low.
