R- Core Transformers are 30 percent smaller, 30 percent thinner and 40 percent lighter than EI type transformers. Sizes are available from 5VA to 1000VA. There are many applications such as office equipment, A/V equipment, medical equipment, CATV systems and electronic instruments. R-Core transformers are suitable for any product that can benefit from a high efficiency, streamlined transformer. Its major features include 90 percent efficiency, low leakage flux, small size and weight. Other features of R-Core transformers include rational design and high-grade material, and suitable for adaptors. Major advantages of R-Core transformers include high efficiency, small size, thin body, light weight, and standardization of production. This transformer delivers extremely low noise. Its insulating effect is excellent and its output power is large.
