Saturable Reactors

Saturable Reactors

Saturable reactors, also known as magnetic amplifiers, use a DC control winding to control the flow of AC power in a circuit. By using a saturable reactor in the primary circuit of a power transformer, the output power to the load can be controlled. This is helpful for driving a variety of loads including motors, furnaces, and even lighting equipment. Because there are no fans or solid-state devices, saturable reactors can operate in environments that would be harmful to silicon-controlled rectifier power supplies due to high temperatures or unclean conditions. Magnetic Specialties can design saturable reactors to fit existing control schemes.
