Usage
The standard AC wall adapter (if you purchased the standard unit) is rated
for 1 Ampere (A. K. A. 1 Amp, 1A, 1000mA), as is the POWER module itself. For
best performance – and this applies to ALL electronics, by the way – you should
never run POWER at its maximum rating. A 60% load (600mA) is the practical
limit for best performance. If you need/want to run it up to 75% or 80%, a greater
capacity adapter is needed to maintain performance. Adapters get hotter as more
power is drawn from them, which increases the internal resistance and thusly
reduces the performance. A 1500mA rated adapter is recommended. The adapter
plug must be a 2.1mm x 5.5mm x 9.5mm barrel-type plug.

Connections
The output connectors are standard
0.25” width male quick-connect terminals,
compatible with the standard Doepfer PSU
harnesses and distribution board terminals.
T+1 & T+2: +12V
T-1 & T-2: -12V
TG1 & TG2: System ground
Compensation jumpers
Power supplies are infamous
for mysteriously becoming unstable. Their
performance is dependent upon the type of
load they are powering, and no two systems
are the same. As I have dealt with this sort of
problem in the past, there are provisions on the
PCB to adjust the regulator output capacitors
to tailor output performance to your specic
load characteristics.
The existing jumpers – JP1(V+) & JP2(V-)
– bypass these provisions, and are required
for normal operation. The positions marked JP3 & JP4 are connected in parallel
with C4 and C8, respectively, and can be used to increase the regulator output
capacitance. Cut JP1 or JP2 as necessary to reduce the output capacitance.
