Of course, it is not too expensive to power home appliances such as routers and cameras.\u003cbr\u003e\u003cbr\u003e The total output power of the power supply is 10 watts, current = total power \/ voltage\u003cbr\u003e The following current parameters are the actual current values ​​without loss of adjustment measured by using a load meter and an oscilloscope:\u003cbr\u003e 5V: Current is about 1600 mA\u003cbr\u003e 6V: Current is about 1300 mA\u003cbr\u003e 9V: Current is about 1000 mA\u003cbr\u003e 12V: Current is about 830 mA\u003cbr\u003e 15V: Current is about 660 mA\u003cbr\u003e 24V: Current is about 410 mA\u003cbr\u003e 30V: Current is about 330 mA\u003cbr\u003e \u003cbr\u003eThe 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.\u003cbr\u003e 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.\u003cbr\u003e\u003cbr\u003e 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. \u003cbr\u003eHow is it different from ordinary adapters?

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.
