HIFI audio dedicated 10W linear power adapter suitable for decoder op amp headphone amplifier CD Output 5V 6V 9V 12V 15V 24V 30V

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) .

The following current parameters are the actual measured non offset current values using a load meter in conjunction with an oscilloscope:
5V: Current of approximately 1300mAh
6 volts: current of approximately 1100 milliamps
9 volts: current of approximately 900 milliamps
12V: Current of approximately 830mAh
15V: Current of approximately 660mAh
24V: Current of approximately 410mAh
30V: Current of approximately 330mAh
Voltage regulator chip configuration: Lingte LT1086CT/IT; LT1084CT/IT
Filter main capacitor configuration: 5V6V9V12V as the gold electrolytic 25V3300UF in the main diagram; 15V24V uses Nippon Chemical KY series 35V3300; 30V uses 50V3300UF.
Output plug: Two shapes of straight 5521 and elbow 5525, with the same quality, default delivery is straight 5521; If you need elbows, please contact customer service. The default polarity of the plug is positive and negative, with a magnetic ring, shielded wire, maximum current of 6A, manufactured 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.
