POWER module, brand new old stock (N.O.S.)

Flight of Harmony

  • $ 6500


POWER is a 10hp power supply for eurorack systems. It has outputs of 12VDC at 1A each, on/off switch, and indicator LEDs for each rail. The mounting depth is 40mm (1 9/16″). It uses a 12VAC wall adapter (not included, but if you need one, let us know) to keep the transformer outside the rack and avoid hum and magnetic coupling issues. Includes 13″ Doepfer-style 18AWG wire harness with quick-connect connectors.

What is this module? POWER is 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 fig. 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.
