MAC MINI POWER SUPPLY 220V HOW TO
MAC MINI POWER SUPPLY 220V PATCH

I think using the LM7824 voltage regulator is best. 9v regulated power supply circuit using transistors and Zenerįor load use the current lower 1000mA.Small Zener diode voltage regulator circuit with PCB.

MAC MINI POWER SUPPLY 220V HOW TO

How to use Zener Diode, example circuit usage.

Here are a few related articles you may want to read: C3 capacitor reduces the spike voltage of output. WithĬ2 capacitor filter is normal to use 0.05 times of C1. We use 0.1A transformer only, And the power of R1 is interesting. You use a Zener diode voltage regulator is enough. Watch in the circuit below. If you have a small load using the current lower of 30mA. You need to use 5A transformer, Diodes rectifier is Bridge 10A 100V.Īnd Capacitor filter is 2,200uF x 5 (in parallel) = 10,000 uF 35V (total). If you want more current up to 5A, 8A, 10A. You may use the voltage of the transformer up is 20V. Or the other hand, if you cannot find more capacitors. You may connect them in parallel to more capacitance. You don’t like to calculate a lot, right? Use 2,000uF per 1A load current right now. Capacitor Filter(C1)-It keeps output voltage is stable when using a load. Or you can get 1N4007 in parallel both can get 2A.ģ. In this I use 1N5402, they can give 3A output. Diodes rectifier(D1-D4)-use 2 times of load current. So, we should 18V 2A secondary transformer.Ģ.

If no load the voltage is about 26V.Īnd In load voltage may be lower 22V. Then, How much voltages of the transformer(ACV)?Īs Principle of unregulated power supply DCV is 1.414 times of ACV. Or 1.5A in this case.īut we cannot find a 1.5A transformer.

We should it is at least 1.5 times of load current. When you remove it, be careful to plug in the line.In the circuit, we have to choose 4 components lists. If you don't understand, you can talk to our customer service. Please prepare 4 kinds of tools before you start. The ability to improve can improve this shortcoming. , hard, not enough strength, insufficient resolution, dynamic low. Listening to music, the intermediate frequency is full, the sound background is clean and neat, and all aspects are greatly improved, especially the most obvious shortcomings of the music using the computer with switching power supply. The board has been tested on the machine. Use good materials, lead wire using silver plated wire.

MAC MINI POWER SUPPLY 220V PATCH

This product package: linear power supply host, 1 patch cord, a MAC linear power conversion module, a power cord. The new sound stage is vital, dynamic and clean instead of the original cold and hard feeling using switching power supply. The different sound stage with this combo can not be obtained from general switching power supply. With this well designed PSU and internal filtering module combo, the smoothness, cleanness and background darkness of sound stage are greatly improved in all aspects. It also uses high quality silver plated wires for connecting the Mac Mini board. It uses high quality parts and three stages ripple filtering (L-C-L-C-L-C) to reduce the power noise. The internal power filtering module is specifically designed for the 2018 Mac Mini. This PSU with specific filtering module combo can replace the original switching power supply of the 2018 Mac mini.
