The ISO-PS is a ultracapacitor power supply using multiple Nesscap (Maxwell) 350F ultracapacitors (5V version uses 3 capacitors; 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 audibility is found when supercapacitors directly power audio devices themselves such as DACs, etc but it also seems to have a audible benefit powering any device in the audio chain.

 

Both voltage outputs are the same voltage (chosen by the purchaser). Apologies for the picture which shows different voltages for each output.

 

ISO-PS Case Sizes: 

  • output voltage upto 5V - case size 160 * 78 * 43mm
  • output voltage >5V and <12V  - case size 160 * 165 * 53mm
  • output voltage >12V - case size 220 * 165 * 53mm

 

Package also includes

  • two heavy gauge DC cables 2.5mm to 2.1mm barrel plugs (DC output sockets are 2.5mm, charging DC input is 2.1mm socket).
  • a 12V or 24V charging PS.

 

You only need to provide an 3 pin earthed mains cable specific to your country  - the same IEC style lead as you use for a kettle.
