SPD-50PRO 50W HiFi Ultra-low Noise DC12V 4A Linear Power Supply For Audio Amp

  

SPD-50PRO was developed for high-definition audio and video devices. It has characteristics such as low ripple, high speed, and low internal resistance. Circuit architecture: UV level noise DC stabilized circuit with precision voltage reference, high-speed operational amplifier, and high-power transistor. At the same time, the circuit adds HiFi filtering inductor with CLC high current, The EMI isolation level further enhances the quality of DC power supply. 2-inch TFT high-definition display screen can monitor current, voltage, and power in real-time.

And it is equipped with a temperature sensor, which can monitor the temperature inside the machine. The output DC voltage can be fine tuned within a range of ± 5%. SPD-50PRO uses a pure copper wire wound O-type transformer. The iron core of the O-type transformer has the smallest magnetic leakage, high magnetic density, uniform wire distribution, good heat dissipation, highest efficiency, good high-frequency characteristics, large transient, and excellent detail performance. The array filtering capacitor uses Nichicon FW series audio HiFi dedicated capacitors, developed for audio purposes, with excellent performance, and is very suitable for use in audio circuits. It is also adopted by many HI-END audio manufacturers, with good quality, reliability, and excellent sound quality performance. The output uses Toshiba high-power transistor 2SA5200, with a maximum current of up to 15A 150W and low internal resistance, making it easy to handle high current output. Output interface: GX16 Output DC cable plug type: default 5.52.5mm (Polarity: Internal + / outside-) Adjustable output range: ± 5% Board mounted fuse: 5X20 (1A) Ripple: No load 0.05MV pure resistance load on load test. 1 × 50VA Linear Power Supply 1 × 5.5-2.5MM DC Output Power Cord 1 x AC Power Cord.
