Toroidal transformers

Toroidal transformers are built on ring magnets and are designed for use in electronic equipment, communication devices, domestic electronics equipment, and in medical equipment. Toroidal transformers have gained wide application in power sources for burglar and fire alarm systems, in step-voltage regulators, as well as for power supply of lighting fixtures including halogen lamps, and in equipment for street and landscape lighting control.

LLC "Yudzhen" serially manufactures toroidal transformers with power from 1 to 9000 VA designed for equipment and devices of industrial, special and domestic application and working with AC power supply of 50 to 400Hz. Transformers are built on twisted strap toroidal magnetic cores. Materials of thermal resistance class F according to GOST (State Standard) 8865-87 are used at transformers manufacturing. Transformers manufactured are of II class of electrical accident protection according to GOST 275700.0-87 (GOST P IEC 335-1-94). At customers request it is possible to install reusable and disposable thermal fuses. Acceptable deviations of input voltage shall be specified when placing an order. Customers requirements to dimensions, leads location, etc. are considered at design of a transformer. Our manufacturing code is PKFL () since 1.01.05. Previously we used designation ARGO.
