WARNING:
In some countries it may be required that mains wiring be performed by a qualified electrician - Do not attempt the power supply unless suitably qualified. Faulty or unsuitable mains wiring may result in death or serious injury. All mains wiring must use mains rated cable, segregated from input and low voltage wiring as required by local regulations.
MAPSU Overview:
MAPSU Overview:
The Modular Audio Power Supply Unit is a very versatile module.
It can be configured as a 3A or 5A module.
Connecting the DC positive output and the DC ground output of 2 Boards we obtain a high quality dual PSU, while populating R1X1 with 0.015 Ohm ballast resistors it's possible to parallelize more boards to obtain even more current handling.
The board can be used as AC/DC converter or as DC/DC converter not populating the bridge rectifier and installing the 2 jumpers indicated on the PCB.
This give us the possibility to create very precise voltage regulation installing two boards in series. The first board will act as AC/DC regulated converter, while the second board will works as a DC/DC voltage regulator.
