Stainless steel sealing cover 54VA British oxygen-free copper 6N OFC enameled wire ring transformer
The transformer core is imported from the UK, and the 0.27mm thick non-breaking steel sheet is wound. The quality is good. The primary and secondary coils are wound by the 6N oxygen-free copper OFC enameled wire with a low internal impedance temperature of 220 degrees. The grade coil is provided with a copper film as a shielding layer between the primary and secondary, and the whole anti-interference and noise isolation capability is strong. Purely hand-wound secondary, using balanced radial cable method, double-wire winding, etc., the consistency of voltage and output current of each group is within +/-0.5%, there will be no vibration and noise, each transformer Will be shipped after being fully qualified by load, aging, insulation, etc.
The primary line diameter is 0.33mm. According to the calculation of 3A 1 square, the wire diameter can output up to 59W, and the energy source is endless. The primary DC internal resistance is only 31 ohms, which is lower than the famous transformers such as Talema and Jian pig. These imported transformers typically have a primary DC internal resistance of 50 W of approximately 50 ohms. The static current of each transformer is only about 3ma, the loss is small, the adjustment rate is as low as 200W transformer level, only 8%. It can be seen that this transformer is a high quality product. Diyer, who used the transformer I designed and manufactured in the past, is very clear. My transformers are very neutral, wide in frequency, fast in speed, no loss in density, no loss of detail, and transient tyranny. This is what I have been trying for years. The transformer and stainless steel cover are specially made, and the middle fixed mast has no contact with the stainless steel cover to ensure that there will be no short circuit after installation. This transformer, I sell the details, is the material, the craft, the sound.
