17W power transformer Z11 iron core for multi-voltage and multi-winding debugging experiment, pure copper enameled wire.
Multi-voltage, multi-winding, experimental installation, repair and debugging, etc., EI57X35mm iron core.
Input AC: 0-230V, primary and secondary shielding end.
Secondary output voltage: 0-7.5V-12V-12V-15V-18V-20V-22V-25V-34V 500mA
All copper enameled wire is wound, high-quality EI iron core Z11 silicon steel sheet is wound with 57 sheets, the sheet thickness is 0.35 mm, and the stack thickness is 38 mm. The transformer makes full use of the package space to wind the enameled wire without cutting corners. The primary and secondary have shielded soldering lugs.
Each transformer is tested with 220V AC voltage, no vibration, no noise, no short circuit and hot phenomenon, exquisite workmanship and high quality. Transformer lead input and output. The transformer has low temperature rise, no vibration, and works quietly and without interference. It can be used for preamps, amps, motorcycles, DIY manufacturing, etc.
The Red Bull clip is fixed by iron hoops and weighs about 0.74Kg.
*************************************************
There is also a power transformer wound with the same specification Z9 material core. The large material core is removed from the imported large transformer, and then cut and punched into various small specifications. The annealing process is better than the new material.
The thickness of Z9 silicon steel sheet is 0.24mm, and the magnetic induction intensity of Z9 is higher than that of Z11 and the inductance is larger than that of Z11. The thickness of the Z11 silicon steel sheet of 0.35mm is very good. In the same wire package, the inductance of the Z9 chip is more than 30-40% larger than that of the Z11 chip. The thinner the silicon steel sheet iron chip, the smaller the eddy current generated, and the higher the efficiency.
Under the same 220V voltage, the thin film can reduce the no-load current, improve the use efficiency, reduce the temperature rise, and weaken the external leakage magnetic field interference.
