THE BEST POSSIBLE QUALITY POWER
Designed to provide the best possible quality power to our USB & NET Cards; default voltage is 5V at each output. As it can be used with any other equipment (DAC, USB converter, network equipment, etc.) that requires up to 3A of DC power, 9V and 12V versions are available too -please specify Voltage in a purchase note. Each output can be made with a different Voltage and different connector type/size at no additional cost!
TWO INDEPENDENT DC OUTPUTS
Features two independent galvanically isolated DC outputs, each capable of delivery up to 3A to load. Because each output has an independent isolated ground, it is possible to power any two devices at the same time, without any degradation.
JCAT TRUE LINEAR DESIGN
In contrast to many so called ‘linear power supplies’ on the market, the OPTIMO 3 DUO does not use any switching power supplies. 12x State-of-the-art LT3045 ultra low noise linear voltage regulators (6x per output) are used. The result is perfectly clean DC voltage with noise level below measuring range (< 2uV). Regulator board is optimized for low noise and impedance. PCB is made with double thick copper, components are surface mount and layout is optimized for shortest signal path.
Design for specific fixed output voltage allowed us to have optimal operating point and minimal thermal stress for all components. Even that no user adjustable voltage is a bit an disadvantage this is the best solution from performance point of view. It features low noise discrete rectifier made of high quality Schottky diodes. Six state of an art LT3045 linear regulators are paralleled not only for high output current but also for noise and output impedance performance boost. In controlled environment the RMS noise is below what we can measure.
Our bespoke massive low induction 100VA transformer with magnetic and electrical shielding is sealed in stainless steel cup with epoxy resin, this guarantees noiseless operation. Transformer is designed to deliver all it’s power in linear part of core magnetic characteristic, with minimal stray field and impedance for best performance. It has Teflon insulated UP-OCC connection cables, and is mechanically decoupled from the chassis by industry standard vibration dumpers.
SUPREME AUDIO-GRADE COMPONENTS
The OPTIMO 3 DUO incorporates supreme quality audio grade capacitors. Internal wiring is made of high-purity OCC copper. The enclosure and the layout of the PSU is optimized for lowest possible mechanical noise. All these enhancements, developed through intensive listening tests, significantly raise performance.
THE BEST CONNECTIONS
For pure voltage transmission the OPTIMO 3 DUO comes with high quality sockets from Furutech and Neutrik. Two high quality 1.2m PC-OCC 0.7mm² double shielded DC cables with 5.5mm x 2.1mm DC barrel plugs (2.5 plugs available on special request) are included which guarantee superb connection. We use high quality gold plated billet aluminum plugs.
OPTIMO 3 DUO chassis is bended from a single thick sheet of laser cut stainless steel for high structural rigidity and low mechanical resonance. Stainless steel is not only much stronger than aluminum, typically used in such enclosures, but also is a non magnetic material. This is very important for best performance as magnetic materials can introduce additional noise. For this reason also all bolts, nuts and other small mechanical parts in our OPTIMO 3 DUO PSU are made of non magnetic stainless steel.
