ADDAC System - 900 Power Delay NEW - PDN
sold out at the moment
This small board was designed to bring some extra flexibility and customization regarding powering up a modular system.Whenever a modular system is turned on there's a current spike upon startup that will momentarily influence the PSU output and can take up to a couple seconds for the PSU to stabilize to it's stated specifications. PSUs can also have some delay between their power lines where one polarity is provided prior to the second one. They also commonly have a ramp like startup. All this is common and normally not a problem. While most modules are fine with this situation, there are others that can suffer from this and in a worst case scenario won't startup correctly. Some modules can also be sensitive to the timing of the ±12v, some may require both to arrive at the same time others won't start if -12v arrives prior to the +12v, etc.This small board allows to time the deployment of power to a specific module, it can delay each power line independently by 3 seconds, meaning that after powering up your modular it will wait for 3 seconds until it will provide power to the specific module connected to it. This delay time can also be customized by the user replacing a couple capacitors.Using this small board with more sensitive modules allow them to power up at a time past the initial spike and where the PSU is already stable and it will guarantee that the ±12V is delivered at exactly the same time.Besides this very technical use there are other creative and useful uses, for example plug it to those specific modules that "drive" your patch, like a sequencer or a clock and have them power up later so that other modules have time to start up and stabilize before starting up the clock. Go even deeper in this idea and have diferent 900PDs with diferent capacitors that will allow you to "program" a sequential module power up, useful for generative patches that run on a power timer in exhibitions and galleries.One more useful hack is to use it in those cases where your frame won't power up due to the initial current "spike", making it going over its limits and trip the protection mechanism failing to startup. The usual "hack" is to unplug one or two modules allowing it to power up and then connect the extra modules in. ***Warning*** power up issues like these simply means your PSU is close to its maximum and the pcb shouldn't be used as a permanent fix and we advise upgrading the PSU. However it will make it easier in that situation where you add one last minute module for that gig in a few hours and that extra module trips the psu protection, then as a temporary hack the pcb will make it easier for the frame to power up at the gig.There are 2 sets of jumpers to independently set the power line to be delayed, -12V, +12V or both.This pcb will be plugged onto your busboard and, in turn, allow a ribbon power cable to be connected to it.There are 2 models ADDAC901PDO for Old style Busboards and ADDAC901PDN for New style BusboardsDISCLAIMER: Both the ADDAC901PDO and the ADDAC901PDN are not to be used with modules that require external +5V supply.DIY-Kit-Type:SMD-Kit-1.

EURORACK POWER
RELIABLE POWER SUPPLY FOR ANY EURORACK SETUP
To run your modular synthesizer system reliably and safely, you’ll need a dependable power supply that delivers the standard Eurorack voltages: ±12V and, in many cases, +5V. These voltages are supplied via the standard 10- or 16-pin Eurorack ribbon cable, which connects your modules to a busboard or power distribution system.
At Exploding Shed, we offer a wide range of Eurorack power solutions tailored to different case sizes, power demands, and levels of DIY involvement. Whether you're just getting started or you're an experienced builder planning a large, multi-row system, we have multiple Eurorack power options to suit your needs.
Our selection includes active busboards, which combine power regulation and distribution in one compact, easy-to-install unit. These are ideal for both new builds and system upgrades. The Active busboards we sell ensure even power distribution across all connections.
ACTIVE, PASSIVE, AND DIY POWER OPTIONS
We also carry passive busboards, which are meant to expand the number of module connectors in your system. These boards do not regulate power themselves but are designed to be connected to an already-powered active busboard or power distribution module.
In this section, you’ll also find powered eurorack cases, offering a plug-and-play solution for those who want to get up and running quickly. Our range includes portable options like the 4ms Pod Cases, which are perfect for smaller, focused setups. These durable cases come with built-in power and are great for live performance or travel.
For those who enjoy hands-on building, we also stock DIY cases from brands like Befaco, which combine flexibility and quality. These kits allow you to assemble your own case and install power exactly the way you want it—perfect for tailoring your rig to specific requirements.
No matter your level of experience or the complexity of your setup, you’ll find the right power solution here to keep your modules running smoothly and consistently. Reliable power is the backbone of any modular system—make sure yours is up to the task.
