iFI Audio / iPower 9V

9V DC power adapter with active noise cancellation to reduce EMI/RFI noise.

■DC power adapter ■Audiophile standard ■Low noise specifications iPower uses "Active Noise Cancellation" to cancel EMI/RFI (electromagnetic interference, radio frequency interference) noise entering the system. iFi is 10 times quieter than previous power adapters, 20 times quieter than audiophile-level linear power supplies and 1000 times quieter than standard SMPS (switching power supply) adapters. ■iPower for LED lights too iPower also solves the flickering problem in LED lights. A power supply that provides constant current and voltage like the iPower ensures that the current supplied to your LED system remains stable regardless of fluctuations in your household AC power. ■Active Noise Cancellation+(ANC+) An exceptionally quiet power supply. Noise floor measurements show it is 100 times quieter than a normal noise filter. ■Specifications Input: 100-240V AC Output: 9V/2.0A Plug: 5.5 x 2.1mm Cable length: Approximately 1.8m Output conversion plug: 5.5×2.1mm input/5.5×2.5mm output ('C' black) 5.5×2.1mm input/4.8×1.7mm output ('F' black) 5.5×2.1mm input/4.0×1.7mm output ('G' black) 5.5×2.1mm input/3.5×1.35mm output ('H' black) 5.5×2.1mm L-shaped extension 5.5×2.1mm input/5.5×2.5mm output; polarity conversion plug ('C' white) Noise level: Up to 1uV Size: 82x43x40 mm Weight: 155g
