4N oxygen-free copper O-type transformer 150W dual 18V 22V measured quiescent current 8mA | Обустройство дома

The O-type power transformer is a completely non-cutting iron core made of high-flux silicon steel strip. The transformer made of this round-section iron core has a small volume and good electrical performance, and is an ideal transformer. Compared with the toroidal transformer: a. The average coil length is reduced by 11.4%-30%; b. The coil has no folding angle, which makes the magnetic field distribution more uniform. Structural features: the core has no fracture; the section is approximately circular; the oblate structure, the height is short, the diameter is larger; the more uniform, the leakage magnetic is smaller. Compared with the R-type transformer, the coil is not limited by the skeleton, and the coil is tightly attached to the core, which is better coupled and more efficient. O-type transformer in the sound quality of the alcohol thickness, in the actual comparison, there are significant differences 4N imported pure oxygen-free copper enameled wire wound, the lead wire is oxygen-free copper galvanized. The air feel is very good, the whole frequency band is transparent and natural. The lead wire is oxygen-free copper tin platingPower: 150 wattsInput: 220V/230VThe core is surrounded by a complete Z10 (0.27mm) imported iron chip.The iron core is varnished in a special mold for one week, no welding, no cutting and no vibration.Certified oxygen-free copper wire,Primary and secondary insulation treatment (unshielded lead) optimized for audio.The measured static current of 150W is 8mA, which is as static as the deep sea O-type transformer. Combines the advantages of R-type transformers and ring changes. Real-time high-frequency characteristics are good, the transient is large, and the details are in place.Generally speaking, the sound of the ring cow is good, the momentum is large, the magnetic leakage is small, it is quiet, and the temperature is low. R cow's voice is warm, the internal resistance is low, the subtle state is very good, and the high frequency extension is excellent.Dimensions 39×116 mmMounting size M8 screwPacking Transformer 1 pc, 1 screw, 1 flat pad, 1 spring pad, 2 rubber pads, 1 iron cover
