AUDIOPHONICS PSU S3-LP Linear Power supply Module DC LT1083

The Audiophonics PSU S3-LP power supply module has been designed to provide a clean power supply to an amplifier or other audio circuit.

It has a potentiometer and jumper to adjust the voltage from 5 to 24V from an AC voltage source of 5 to 22V AC respectively.

Its particularly rigorous design, and the quality of its components, make it an excellent choice for powering a digital amplifier or any other low voltage high-fidelity element such as certain DAC converters, headphone amplifiers, etc...
So many devices for which it contributes to improve the sound quality.

The Audiophonics PSU S3 makes use of 4 fast switching 2CZ2545 A9 diodes.

On the filtering side, 10 Rubycon capacitors of 2200uF/35V with an ESR of 0.0019 Ohm and a current capacity of 3.1A per capacitor.
Once the voltage is stabilised, it is then regulated by means of a LINEAR TECHNOLOGY LT1083, renowned for its low ripple (0.015%).

Features:

• 4 diodes 2CZ2545 A9.
• 2 diodes 1N5408.
• 10 Rubycon capacitors 2200uF/35V.
• Voltage regulator LINEAR TECHNOLOGY LT1083 5A.
