Toroidal transformers which use magnetic cores with a toroidal (ring or donut) shape. They are passive electronic components, consisting of a circular ring or donut shaped magnetic core of ferromagnetic material laminated iron only.More
Voltage Converter W/Universal Socket Plug in 'MAXCON' Voltage Converter will electricity to match U.S. appliance rating. Just plug in your appliance into the female side of the converter and plug male side of converter to electricity outlet.More
A control transformer provides good voltage regulation, and is also designed to provide a high degree of regulation during a brief period of overload condition. Isolation transformer will purify the output circuit frequency in a standard limit.More
The potential transformer is an instrument transformer used for the transformation of voltage from a higher value to the lower value. It is step down the voltage to a safe limit value which can be easily measured by the ordinary low voltage instrument like a voltmeter and etc.More
In electronics, a ferrite core is a type of magnetic core made of ferrite on which the windings of electric transformers and other wound components such as inductors are formed. It is used for its properties of high magnetic permeability coupled with low electrical conductivityMore
Variac transformers are AC voltage controls that provide a variable AC voltage. Their distortion free output is ideal for sensitive electronic applications. Auto-transformer (sometimes called auto-step down transformer) is an electrical transformer with only one winding.More
An inductor, also called a coil, choke or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. Electrical reactors can reduce short-circuit currents.An inductor typically consists of an insulated wire wound into a coil around a core.More
Toroidal transformers are inductors and transformers which use magnetic cores with a toroidal (ring or donut) shape. They are passive electronic components, consisting of a circular ring or donut shaped magnetic core of ferromagnetic material laminated iron only.
A toroidal transformer is more compact than other shaped cores because they are made of fewer materials and include a centering washer, nuts, and bolts resulting in up to a 50% lighter weight design. This is especially the case for power devices. Because the toroid is a closed-loop core it will have a higher magnetic field and thus higher inductance and Q factor than an inductor of the same value with a straight core. This is because most of the magnetic field is contained within the core. By comparison, with an inductor with a straight core, the magnetic field emerging from one end of the core has a long path through air to enter the other end. In addition, because the windings are relatively short and wound in a closed magnetic field, a toroidal transformer will have a lower secondary impedance which will increase efficiency, electrical performance and reduce effects such as distortion and fringing. Due to the symmetry of a toroid, little magnetic flux escapes from the core. Thus a toroidal transformer, radiates less electromagnetic interference to adjacent circuits and is an ideal choice for highly concentrated environments. Manufacturers have adopted toroidal coils in recent years to comply with increasingly strict international standards limiting the amount of electromagnetic field consumer electronics can produce.
