Technical Features:
Full discrete no op amp using, linear power supply, Maximum support 15A current output.
Low noise, Actual measurement resistive load of less than 5MVPP, capacitive load 10UVPP.
With 1.6HZ low-pass filter, a high power supply rejection ratio.
Voltage negative feedback technology, Output voltage from 0V slow (4 seconds) internal up to the target voltage.
MOS pipe output by as regulator, is not easy to shock wear, good thermal stability.
S12 is a high-performance DIY single-rail linear regulated power supply (PSU). It is basically half the dual-rail PSU 22, and possesses the
same low-noise, high-current, excellent line/load regulation, wide-bandwidth, and stability characteristics. S12 is ideal for DIY stereo headphone
amplifiers, preamplifiers, DACs, network media players, and other applications requiring a single-rail regulated PSU.
The circuit uses all discrete components (no integrated circuits), and features high-current MOSFETs as the output "pass" devices.
S12 is derived from the 22, which is the result of a community service project for the audiophile hobbyist. The schematic diagram is open source.
The circuit design, as well as the printed circuit board layout are the work of AMB with participation from the DIY community. It is designed to be
relatively easy to build, but it is not recommended as a first-time project for the beginner.
PCB size: 102mm * 86mm * 50mm (L*W*H)
This board can built 5V 9V 12V 15V 18V 24V 30V etc. several kinds output votlage. Juse need change the "VA" and "RA".
And the output voltage can be minute adjustment . it is very easy! add one suitable transformer. you will can built a Hi-end Linear Power supply.
NOTE: This is a Welding debugging board OK.

Note 1: When the continuous output current greater than 2A, Please put the rectifier (MUR1560) installed to full aluminum chassis or large
heat sink, Also note that the insulation.
Note 2: IRFZ24N please according to the calorific value to do a good job of insulation and heat dissipation.
I store sales have DC output cable, if you need please to Please find shops category Other Accessories, Or the search keywords GX16.
