Ultralow Noise Linear Power Supplies
A range of brand ultralow noise linear power supplies designed to out-perform standard linear PSUs and at a pricepoint that is realistic!
All our miniature linear power supplies are linear supplies with dual-regulation and EMI supression filtering.
The power supply design features a toroidal transformer with discrete schottky rectifiers and over-specified Nichicon audio-grade capacitors.
We use two stages of regulation, with a first stage designed to provide a clean smooth power to the secondary filtering and regulators. This supply then passes through LC and ferrite filtering to eliminate any residual Electromagnetic Interference (EMI) before passing to ultralow noise LT3045 regulators, used in parallel to increase output capacity and provide world-class clean power supply.
The final result – a power supply that filters out almost all mains-borne EMI and delivers a noise performance on the output of only 0.8μV RMS across the whole audio frequency spectrum.
And all this in a tiny box measuring only 110mm x 104mm x 40mm
SuperCap PSU
SuperCapacitor fully isolated PSU
Our flagship power supply, offering unsurpassed Electromagnetic Noise isolation.
Utilising two switched banks of SuperCapacitors, the output of the power supply is permanently isolated from the mains input providing all of the isolation benefits of a battery supply without ever needing to recharge.
We use specially silenced reed relays to provide true isolation from the mains. Other similar designs use solid-state relays which conduct EMI at high frequencies due to the parasitic substrate capacitance inherent in their construction drastically reducing their effectiveness for this application.
