220V to 110V isolation transformer power 40W voltage can be set Z11 iron core pure copper enameled wire winding British Red Bull bracket fixed
The core size EI66 is 28mm thick, and is fixed by British copper-plated Red Bull stand or riding clip. It has a high-end appearance, imported Z11 silicon steel sheet core, 0.35mm thick, one piece against the other, varnished insulation process, normal power voltage , No vibration and no sound, low temperature rise and quiet transformer.
Transformer primary input voltage 220V/235V optional, shield lead between primary and secondary. Secondary voltage 0-55V-110V current 40mA, can also be connected to 55V-0-55V dual voltage three lines output for audio pre-use. Can also be customized according to requirements.
The input voltage is 220V or 235V according to the actual mains voltage.
There are two types of transformer fixing methods, which can be purchased according to demand:
Horse riding clip fixed, British Red Bull bracket fixed, weighing about 0.86KG
Affirmation: Because the local mains voltage is not standard 220V (mostly more than 230 to 240 volts), the measured voltage value will be different due to different test conditions and equipment and different loads, there will be a voltage drop after the load, will It will be different from the voltage marked on the transformer. There is an error in the actual voltage measurement. The advertising voltage parameters are for reference only.

This transformer can be used for imported 110V small electrical appliances or audio power supply, which can significantly improve the sound effect, far better than the common inductance-capacitance filter. Suggestion: It is used for transformers or CDs, pre-stages, decoders and power amplifiers with rated power within 40W.
Isolating transformers are mainly used for isolating and absorbing the “common-mode noise” interference of the stray signals on the power grid, which makes the sound more pure and protects the circuit from accidental surge current. Isolation transformers are also called safety insulation transformers. The primary and secondary are not connected, it is the regenerative energy generated by the transformation of the electric field primary coil electric field → iron core magnetic field → secondary coil electric field. The inductance of the iron core transformer is large, and the loss of various clutters is quite large. The interference wave is not easy to be induced from the primary primary coil to the output of the secondary secondary coil, so as to eliminate the purpose of purifying the power supply. The power supply of the isolation transformer is relatively clean (isolated from the commercial power supply), so this type of transformer is often used in the upgraded audio of the motor. The disadvantage of the isolation transformer is the cost, volume, weight and other issues. Isolation transformers are safety transformers, because even if the output voltage of this cow is 110 volts or higher, people will not get an electric shock when they touch a line with their hands (even without wearing shoes). Of course, when you touch the two wires at the same time, you must be electrocuted. This kind of cattle is the primary voltage induced by the magnetic field to the secondary and then become 110 volts (or higher or lower voltage) output. Using a multimeter to isolate the two wires of the cattle voltage input and the two wires of the voltage output is non-conducting. At this point, you should understand that there is no electric shock when touching a wire at the output. Because the output terminals are not connected to the city power, how can you get an electric shock? That is to say, when the isolation cow you used burns out, it will not kill your machine, because the primary and secondary voltages are not connected, and will not flow into your machine.
