An efficient and compact electrical audio component, the VTX-146-0001 Series is specifically used in audio equipment to convert high-voltage AC mains power into lower voltages suitable for use by audio circuits. Its toroidal (donut-shaped) core design minimises electromagnetic interference (EMI) and hum, resulting in cleaner power delivery and improved sound quality. It is favoured in high-fidelity audio systems for its low noise, high efficiency, and compact size. These toroidals are made with 2 layers of GOSS band shielding for added noise elimination. * Audio grade grain oriented silicone steel core * Centre potted with captive nut in centre * 2 layer magnetic GOSS band shielding * Wide input voltage range from 110 to 240V AC * UL and EN61558 approved * Silent operation and high efficiency (83% +) * Input voltage range from 110 to 240V AC
