Mini distro board - AC mains
powered : 28€ shipped
This mini distro board works with a +/-15V PSU (Mean Well PD2515 or other) and is able to power up to 4 modules. It can also be used as is as a passive multiple to expand an existing power board. Edge contacts are gold plated. Optional LEDs show each rail is working. The quiet and noisy grounds can be shorted on the board if needed. The 3 pads not PSU-related are interconnected. BOM (adapt it to your own needs) - 2 x 47uF electrolytic capacitor - 2 x 100nF ceramic capacitor - LM7812 +12V regulator - LM7805 +5V regulator - 2 x TO-220 heatsink - Mean Well PD2515 or other +/-15V PSU - 4 x 3mm LED (optional) - 4 x resistor (optional - value depends on the LED)  Mini distro board for 208 / Easel - AC mains powered : 28€ shipped Same as above but with 2 edge connectors only to fit into a 4U boat together with a 208, below the sequencer. This board can be mounted on top of the Mean Well PD2515 with standoffs to save room, the mounting holes match.  Mini distro board for 208 / Easel - DC 12V powered : 28€ shipped This board works with an external DC 12V adapter and fits into a 4U boat together with a 208, below the sequencer. It's the most compact solution. BOM - 4 x 100uF electrolytic capacitor - 4 x 100nF ceramic capacitor - LM7805 +5V regulator - Traco Power THL 30-2423WI or Mean Well DKMW30F-15 or similar +/-15V DC converter - Good quality DC 12V adapter, 1.5A or more  The PCBs come unpopulated and without parts. All uses are at your own risk and I assume no liability for personal injury or damage to equipment or loss of use caused directly or indirectly by the use of any of the PCBs. Although the installation is quite simple it should only be performed by those experienced in electronics. |
