eBay

This is assembeld and tested board. we can make Single DC3.3V-DC32V all kinds output voltage.

buyer must need tell us what the output DC voltage is you need. can add a order note or send ebay message to tell us. thanks

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.

PCB size: 102X86mm

Note: you need add extra heatsink for the 2pcs Field effect transistors IRF9Z24N. and if you need output current is high, the 4pcs rectifier diode also needs to strengthen the heat sink.

Package inlcude: Assembeld Super Liner Power supply board X 1

This is a high-performance single-rail linear regulated power supply (PSU). It is basically half the dual-rail PSU σ22, and possesses the same low-noise, high-current, excellent line/load regulation, wide-bandwidth, and stability characteristics. S22 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.

this PSU is derived from the σ22, 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.
