short discription:
left part:
fixed voltage outputs +3,3V +5V +5Vreference +12V +15V galvanic
seperated from second part: -5V -12V -15V
optical voltage control by red
LED's for each of the 8 outputs and all short circuit
protected
middle part:
digital functiongenerator (source from mikrontroller.net, Andreas
Schwarz)
sinus rectangle sawtooth and triangle signal 0-20kHz, 0,5Hz
resolution
amplification and voltage adjustable, +-10Vpp
galvanic
seperated from other parts
right
part:
2 identical voltage supplies 0-15V
5,3A
adjustable by 10 turn potentiometer
the 19'' housing is
shortened to fit above the 19'supply and not to block the fan
outlets
built for
development, and I would miss it a lot on my table
left part:
only a few fixvoltage regulators and
inverters: 
(the symbols of the rectifiers are wrong)
fits perfect on a euro-PCB:
middle part:
see the project on
mikrocontroller.net
right part:
0-15V 5,3A out of
LT1083 fixed voltage regulators.
The helpvoltage out of addinional winding
on the transformer come through 3 fold RC combinations
everything right
calculated and the voltage could be exactly adjusted from 0,00V to its
maximum
