Vertical Bobbin Shape High Frequency Power Transformer 250W Compact Design

ER42 HIGH FREQUENCY HIGH VOLTAGE POWER SUPPLY TRANSFORMER STEP DOWN TRANSFORMER

High voltage transformers are normally used in high voltage labs for testing purpose. This transformer is subjected to transient voltages and surges during their normal operation when the insulation under test breaks down. To withstand these impulse voltages,the insulation of these transformers must be carefully designed. These are usually single phase, core type transformers.

RUIYUAN was established in 2002, located in Tianjin City,the second largest port city in China.We have been focusing on different kinds of high quality wires: enameled round copper wire, rectangular enameled copper triple insulated wire, silk covered Litz wire, bonding wire and special enameled wire for 21 years.Ruiyuan is one of the pioneers in producing micro thin enameled wires below 0.03mm in China. Our R & D team has 20 years of market experience. In 2019, our finest diameter is 0.011mm, and mass production has been achieved. All of our products are UL, RoHS certified, in line with industry standards IEC60317, JIS C 3202, NEMA, NW82.
