Before purchasing, please determine by yourself whether the voltage and power of your electrical appliances match the power supply, whether the plug specifications are compatible, whether the plug polarity is internal positive and external negative or external positive and internal negative (this is very important, if the positive and negative poles are wrong, the machine will burn).

Because I was not satisfied with the performance of the commercially available adapters, this product was designed, mainly for HIFI audio products, to make the music background more quiet, dynamic and smart, and the high dynamic current comes from the large ripple electrolysis and ultra-low internal resistance voltage regulator IC. Of course, it is not too expensive to power home appliances such as routers and cameras.

The total output power of the power supply is 10 watts, current = total power / voltage
The following current parameters are the actual current values ​​without loss of adjustment measured by using a load meter and an oscilloscope:
5V: Current is about 1600 mA
6V: Current is about 1300 mA
9V: Current is about 1000 mA
12V: Current is about 830 mA
15V: Current is about 660 mA
24V: Current is about 410 mA
30V: Current is about 330 mA

The peak current is 3A, which is related to the large capacitance. 9V12V15V filter large electrolysis withstand voltage of 25V3300UF; 24V and 30V filter large electrolysis withstand voltage of 50V3300UF.
Output plug: straight 5521 and elbow 5525 two shapes, the same quality, default delivery with straight 5521; if you need an elbow, please contact customer service. The plug polarity defaults to positive and negative, with a magnetic ring, and the wire is a shielded wire, the maximum current is 6A, and it is made in Taiwan.

Some customers and friends have reported that the output voltage measured with a multimeter is higher than the rated voltage (for example, when buying 5V and measuring 5.2V), this is normal. No-load must be higher. After the load is added, there is loss due to line voltage drop. The electric appliance is just about 5.1V, which is very standard. The blue potentiometer can be adjusted to 5.0 volts, but the adjustment is unreasonable.
How is it different from ordinary adapters? Please see the following picture description:

Recently, some comments have linked this power supply to a switching power supply. What is a switching power supply? Your mobile phone charger is a switching power supply, and the Philips table lamp power supply is also a switching power supply. No matter how good a switching power supply is, its peak-to-peak ripple is about 100 millivolts mv, but the linear power supply can easily be controlled below 10 millivolts. For a qualified Walkman, radio, decoder, headphone amplifier or preamplifier, the power ripple below 10 millivolts is low enough, so low that the most sensitive headphones or speakers can't hear it. If using our power supply (with ripple peak-to-peak value within 2 millivolts) still cannot solve the noise problem, please look for factors other than the power supply.
