12V 2A 25W Ultra-Low Noise Linear Power Supply with Talema Toroidal Transformer

12V 2A 25W Ultra-Low Noise Linear Power Supply, Noise Floor 1μV
Supports 100-120VAC
Please check the current and voltage specifications of the device you intend to use before purchasing.
Images from the 4th picture onwards are from the manufacturer's website.
This is a high-end model equipped with a high-density discrete circuit, achieving a noise floor of 1μV (manufacturer's stated value). 1μV = 0.000001V (this is the noise level, not voltage accuracy). Noise from the power supply is virtually eliminated.
The 1μV noise level is comparable to the iFi iPOWER ELETE, but as an analog power supply, the noise frequency is 50-60Hz and its multiples, which is less than 1/1000th the frequency of the iPOWER ELETE's switching speed of over 100KHz.
The toroidal transformer is made by Ireland's Talema, often used in high-end amplifiers.

Can supply ultra-high quality, high-precision power to DACs, headphone amplifiers, DAPs, phono equalizers, network equipment, etc. that use 12V type power supplies, such as CHORD Qute HD, Qute EX, 2Qute, FirstHugo, FiiO M17, iBasso DX300MAX, etc.
The sound quality is incomparable to ordinary switching power supplies. The depth and purity of the sound are different.
Since there is no high-frequency circuit, high-frequency noise is not generated in principle. Even if there is voltage fluctuation, it is in the sub-audible range.
Equipped with real-time digital voltage monitor.
Two 12VDC outputs with an outer diameter of 5.5mm and an inner diameter of 2.1mm, center positive. Total up to 25W/2A.
Full aluminum case, black painted and black anodized finish with heat dissipation grooves on three sides.
Each output is individually equipped with capacitors and coils to prevent mutual interference.

Dimensions: D160mm W110mm H55mm (excluding protrusions)
Includes one DC output cable with a ferrite core (outer diameter 5.5mm, inner diameter 2.1mm) and a 3-pin power cable.
If you wish to use a higher quality DC cable, change the plug type, or convert the polarity to center negative, they are sold at the following links:
