Z11/Z9 Iron Core Power Transformer 17W Pure Copper Enameled Wire for Multi-voltage Multi-winding Debugging Experiment
17W power transformer Z11 iron core for multi-voltage 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 terminals.
Secondary output voltage: 0-7.5V-12V-12V-15V-18V-20V-22V-25V-34V 500mA
All copper red 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.
Each transformer is tested by 220V AC voltage, no vibration, no sound, no short-circuit hot phenomenon, exquisite workmanship and high quality. Transformer lead input and output. The temperature rise of the transformer is small, there is no vibration, the work is quiet and no interference, and it can be used for preamp, amp, motorcycle, DIY, etc.
Red bull clip iron hoop fixed, weighing about 0.74Kg
****************************************************
There is also a power transformer with the same specification of Z9 material iron core winding. The large material iron core is removed from the imported large transformer, and then cut and punched into various small sizes. The annealing process has better performance than the new sheet material.
The thickness of Z9 silicon steel sheet is 0.24mm. The magnetic induction intensity of Z9 is higher than that of Z11 and the inductance is larger than that of Z11. Z11 silicon steel sheet thickness of 0.35mm is very good. For the same wire package, the inductance of the Z9 piece is 30-40% larger than that of the Z11 piece. The thinner the silicon steel sheet iron core, the smaller the eddy currents 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 interference of the external leakage magnetic field.
