Audiophonics power supply module PSU S4-HP has been designed to provide clean power for an amplifier or any continuous audio circuit.

This version has a 6.5mm pre-drilled aluminum plate to improve heat-dissipation capacity and allow the module to deliver greater power. Those pre-drilled holes make it easier to mount the module into a housing or a heatsink.

It is equipped with a potentiometer and a jumper to adjust the voltage from 5 to 24V from an AC voltage source whose value is between 5 and 20V AC respectively.

Rigorous design and quality components make the PSU S4 HP an excellent choice to power a digital amplifier or any other Low Voltage High Fidelity devices such as DAC, headphone amplifiers for enhanced audio performance. For this purpose, the module uses 2x 1N5408 and 4 x 2scz2545 fast switching diodes.

The voltage regulator is a Micrel 29752, a popular component for critical systems due to its extremely low dropout.

This power supply has an impressive capacity for filtering with no less than 10 ELNA electrolytic capacitors 5600µF 35V (for a total of 56000μF available for filtering). A final output capacitor provides further enhancement for the PSU overall accuracy.
