Above 5V - Supercapacitor Power Supply

Above 5V - Supercapacitor Power Supply

The ISO-PS is a ultracapacitor power supply using multiple Nesscap (Maxwell) 350F ultracapacitors (7V version uses 4, etc). These capacitors have an internal impedance of <3.2mohm delivering voltage outputs with current output ratings upto 3 Amps (but huge instantaneous current delivery headroom) hence the stability of the power supply when under dynamic load conditions - a fundamentally important characteristic needed for the power to audio devices.

 

The important feature in all these PS designs is that there is NO voltage regulator between the supercapacitors & the output - the current is delivered directly from the supercapacitors which makes a large difference to the sound when powering devices in the audio chain. It's a growing realisation that voltage regultaors (even the best ones) react to dynamic current draws (becaus eof their feedback method of voltag eregulation). The largest improvement in audibil
