What is it?
This one is pretty straightforward: a power supply for your modular
synthesizer rig. No sweet spots, no easter eggs, it just makes juice.
POWER was designed with portable racks in mind –– shallow depth,
reduced weight, and keeping the mains transformer outside of the case to eliminate
related noise and heat –– but it can be used to supply any compatible system.
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.
Input Connections
AC jack: CN1 is for the AC adapter jack. Tip wire to the top pin, sleeve
wire to the bottom pin (as shown in g. 1).
Power switch: CN2 is for the power switch. When the switch is turned
ON, pin 1 is connected to pin 4, pin 2 is connected to pin 3.
Output Connections
LED+: From the front side, this is the header next to R3 and is the +12V
LED (red). Anode (longest leg of the LED) to the top, cathode (shortest leg of the
LED) to the bottom.
LED–: From the front side, this is the header next to R4 and is the -12V LED
(yellow). Anode (longest leg of the LED) to the top, cathode (shortest leg of the LED)
to the bottom.
