MINI PURE-DC-4EVR (“MINI”) is the world’s first patent-pending, isolated ultracapacitor power supply with super-regulated DC output voltage. Your MINI replaces the stock “wall-wort” AC-DC power adapters that are commonly used to feed products that take a DC input voltage. [For example: the Sonore microRendu and other small computer modules, USB cards, dacs, preamps, headphone amplifiers, and even small amplifiers and other products & DIY projects requiring fairly low DC voltage(s)] MINI provides isolated, pure DC power with very low output impedance, high bandwidth and excellent transient response characteristics. Just like with our revolutionary LIO modular audio platform, our patent-pending PURE-DC-4EVR circuitry utilized two banks of ultracapacitors. While one bank of ultracapacitors is feeding isolated DC current to the linear super-regulated output, the other bank is charging. The bank feeding the output is NEVER connected to the charging ultracapacitor bank and is 100% isolated from the AC mains at all times. This revolutionary design by Vinnie Rossi provides dramatic performance and durability advantages over every other power supply technology available - whether it is AC (linear or SMPS) or battery power! Each MINI PURE-DC-4EVR is hand-built and factory configured to meet your specific input and output voltage requirements. It also includes a built-in linear regulated charging circuit for the ultracapacitor banks. MINI PRODUCT FEATURES Output voltage is set at the factory to any value from 3.3Vdc to 12Vdc * 2.5A continuous output current (max) / 5A transient current delivery (< 1 sec.) Custom Belleson “SPVR-X” (Super Power, Vinnie Rossi, X = adjustable setting) ‘super-regulated’ output, featuring patented state-of-the-art regulator technology (< 5uV RMS output noise voltage). Built-in linear-regulated charging circuit (no SMPS or DC-DC converter circuits used anywhere) Totally silent switching (SS) of the ultracapacitor banks Fully isolated output voltage to feed your product Red illuminated push-button ON/OFF switch on front panel Banana/Spade/bare wire type output terminals (Red = positive [+], Black = Negative [-] ) Fused IEC power input jack. Internal fused output feed to the SPVR-X regulator. Black aluminum enclosure with power switch on the front panel * Output voltage can be later changed (within the 3.3V to 12Vdc range) with a free factory upgrade to original customers (requires a firmware update and minor hardware change). For second-hand owners, we will still offer this for a service fee. Size: Approx. 6” wide x 7” deep x 3.5” tall Approx. 8 lbs.
