Nobsound Adjustable DC Regulated Linear Power Supply (USB 5V and DC5V-24V output)

Introduction

More and more audio devices are equipped with external power supply like switch power supply or transformer. As we known, power supply plays an important role in affecting the sound quality of audio devices. Switch power supply is efficient with small-size, but the background noise they generate is as several times as the linear power supply and decrease the sound quality. So Douk Audio Studio designs a continuously adjustable linear power supply to improve audio sound quality and for those who love DIY and need different voltage.


Features

①. 2 Kinds of Output Voltage:

  • DC 5V-24V, not like other linear power supplies with a fixed voltage on the market, it can be continuously adjusted for those who need different voltage for DIY and debugging, which is a patent design of Douk Audio
  • USB 5V is suitable for USB devices, and can output 4A current different from other USB power supplies whose output is lower 4A.

②. Actual 25W Output: compared with other so-called 25W linear power supply whose actual output is less than 25W, it can output at 25W stably for a long time.

③. 4-bit Precision Display: unlike other power supply that can only display voltage, the voltage and current value will be shown clearly on its LED display, users can see the actual load of his devices.

④. Universal DC5V-24V Output Binding Posts: we offer 1 DC output cable and 2 cables with alligator clip designed for multi-purpose like connecting whole-machine or DIY debugging.

⑤. Superior protection: with over-temperature, over-current and fuse protection, and good heat dissipation can protect it work at 25W at 50℃ for a long time.

⑥. High-end Material: using pure copper 40W toroidal transformer, high-quality filter inductance and aluminum shell to guarantee the circuit with stable voltage, small ripple and ultra low noise.

⑦. Adjustable Input Voltage: we design 115V/230V AC which is suitable for global, you can choose proper voltage in different countries.

Notice

1.Please debug proper output voltage before connecting, avoiding high voltage burning your audio devices, Douk Audio is not responsible for man-made losses.

2.Since linear power supply emit more heat, we design a fan for its continuous and reliable operation. With slight noise, but not affect its performance.
