LPS-25-USB 25VA Linear Power Supply Low Noise USB 5V DC5.5/2.1 Dual Output for XMOS DAC
Features:
1. The standard output voltage is 5.00V, the user can fine-tune the output voltage through the Adj hole on the back, the adjustment range is usually within 10%.
2. The maximum output current is 3.5A. When the measured power supply is no-load and full-load 3.5A , the output voltage fluctuation is less than 5mV.
3. Use Talema 25VA high-quality sealed transformer.
4. Power MOS + high precision reference + op amp servo power supply, high stability and low noise.
5. Multi-level CLC filter circuit.
6. Accurate to 0.01V LED voltage display, real-time observation of output voltage, pure white LED, moderate brightness.
7. Equipped with trimming resistors to accurately adjust the output voltage.
8. The materials used are all carefully selected brands and models, such as Talema transformers, philips high-current ultra-high-speed rectifier diodes, Vishay BC (philips) capacitors, Panasonic FC, FM capacitors, 0.1% precision low-temperature drift resistance, and large IR Power low internal resistance MOS tube, high current winding inductor filter, etc.
9. USB 5V and DC5.5/2.1mm dual output (internal independent LC filter circuit is separated)
10. Dimensions: 60 (height) x 103 (width) x 155 (depth) mm
11. Net weight: 1.03kg
Application:
This low-noise linear power supply is very suitable for occasions with high power requirements, such as:
1. Various USB decoders that require USB power supply, such as XMOS, Amanero USB interface, etc.
2. Mobile hard drives, digital set-top box, high-definition players, etc.
3. Mobile phone and tablet charger.
Test Chart
In the figure, set the electronic load current to 3A (displayed as 2.989A) (the voltage displayed by the electronic load is not accurate because the large current forms a voltage drop on the test cable)
As you can see in the above figure, when the 3A output is set, the ripple voltage of the power supply is 3.8mV.
Package List:
