PSU

28HP EuroRack module

Power Supply rear panel Module

To be independant of input Voltage (100 ... 240V AC),
the 1st PSU stage is a +/- 15V DC switching power supply.

To supply all modules with a clean and stable distribution,
the 2nd PSU stage is a linear voltage regulator circuit.
The output provides +/-12V DC.

To avoid ground loops, we do not use a Power Bus.
Busses are usually for signals but never to supplying power.
We use star distribution instead of bus distrubution.
Each module has a JST XH 2.54 mm 5pin socket.
Each module has a direct power supply connection.
We use standard lipo balancer cables.
