Features

Overview: The iFi-Audio iPower Elite is an AC-to-DC power supply that provides clean DC power to your 15-volt DC powered devices. iPower Elite features a full unibody, aircraft-grade 6063 aluminum chassis with built-in heatsinks for heat dissipation. The power supply has a special circuit design with specially-selected components to provide a super-quiet noise floor of <1 µV. It has a 39" (1-meter), fabric-covered, oxygen-free copper output cable, a separate IEC C15 AC power cable, and a reverse-polarity plug. This iPower Elite power supply has a DC output of 15V/3.5A.

Active Noise Cancellation II: iPower Elite uses iFi-Audio's latest Active Noise Cancellation II to reduce unwanted noise by adding a second sound wave that is of opposite polarity to the signal (electrical noise) it wants to cancel. This is the same principle used in noise-cancelling headphones. Active Noise Cancellation is more effective than passive noise cancellation, which uses insulating filters to lower noise. The filtering works well on middle to high frequencies, but not on lower frequencies. ANC2 provides over 1000 times more noise reduction than generic power supplies with traditional filters and regulators, and does not result in the loss of DC voltage. iPower Elite also has a noise floor (<1 µV) that is 100 times lower than the Linear Power Supplies (LPS) provided with some audiophile components.

High Performance: Compared to traditional switching power supplies, iPower Elite does a much better job of suppressing high-frequency noise, through the use of solid organic capacitors and semi-conductors in its design. iPower Elite leakage noise is 20 times lower than normal Switched Mode Power Supplies (SMPS). When compared to the original iPower DC power supply, iPower Elite's input filter capacitance is 363% larger (120 µF vs. 33 µF) for better filtration and better dynamics.

Reverse Polarity Adapter: Most DC barrel connections are configured with the tip or center pin positive (+) and the sleeve negative (-). iPower Elite is designed to power those devices. However, because some electronic devices have the opposite configuration, a Reverse Polarity adapter is included to allow you to properly power those "tip negative" devices.

Design: The iPower Elite transformer has an attached 39" DC output cable with a 5.5 x 2.1mm barrel connector. On the other end is an IEC 3-conductor AC power inlet for the supplied AC power cord. This power supply is designed for the U.S., and includes a 5' AC cord with a 3-pronged plug. For use in other countries, a separate power cord for that country will need to be obtained from iFi-Audio.
