A core-type transformer is defined as a transformer that has a magnetic core with a rectangular shape and two limbs or legs. The core provides a single magnetic circuit for the alternating flux.The windings are cylindrical and concentric, and they are distributed over both limbs of the core. The low voltage (LV) winding is placed near the …
R core transformer is mainly used in the production and processing of singlephase products, such as led lights, tvs, computers. Meanwhile, the r core transformer is designed to work as a high voltage and current amplification unit. Meanwhile, transformer is a highperformance, multichannel, compact and durable.
Power. 60 VA. Output Voltage. 0-12V, 5Amp. Input Voltage. 0-230V. R-core Transformers are manufactured using the unique rectangular core with round cross section known as R-cores. The special feature of this transformer is that the core is gap less and continuous. The winding is done on special round bobbins on two parallel legs of the core.

Re: R-Core transformer. Worth it? « Reply #6 on: 25 Jan 2010, 04:46 pm ». The advantages of of R-cores over toroidal transformers (unless the toroidal has a shield between primary and secondary) regarding bandwidth and the passing of noise are quite real and measurable, and IMO, subjectively perceptable.
A transformer core is composed of limbs and yokes that are joined together to form a single structure around which the coils are placed. The manner in which the respective yoke and limbs join together will depend on the type and design of the core. Above is a diagram of a laminated stacked core.
2:22 pm. #10. The 20 va transformer is meant for use in a preamp for which I will use an r-core. The 300 va is for an amplifier (100w) for which I will use a toroid. I have not seen an r-core that is capable of 300 va. I do like audiophonics but shipping to the USA is expensive. 25€ for a 32€ 30 va r-core.
