Please note: this is the 12U kit with 2x 1.5A 5V options included. It includes one Active Eurobus and one Passive Eurobus zone-filtered busboard. 15V DC brick not included. Some assembly required. (See User's and Installation Guide).
We say...
A serious power solution with uncompromising performance and attention to detail. If you're building or upgrading a big case, this should be at the top of your list.
Manufacturer's description
The Toppobrillo Eurobus is a robust new modular power solution for Eurorack - efficient, professional grade power with the lowest in-class noise specs on the market.
Features
- +12V @ 3.5A, -12V @ 2A, +5V @ 3A
- Lowest ripple/ noise in a switching Eurorack power supply. Offers the lowest noise/ efficiency ratio available.
- Zone-filtered, low impedance distribution; extra thick copper, thick traces and 4 layers of meticulously stitched ground plane span entire width of board.
- Fast, stable and robust load regulation.
- Efficient and relatively cool running. 90% efficient at load.
- Soft-start and short recovery.
- Over-current, over-voltage and thermally protected.
- 20x keyed power connects.
- High reliability poly cap distributed capacitance; very long life, very low ESR.
- Bus breakout header for peripherals and remote access.
- Small footprint and low profile. Assembled Active Eurobus dims: approx. 250mm L x 85mm W x 12.5mm at the highest. (over the regulator board)
System
The Eurobus system consists of a SWB65 regulator board paired with a low-impedance, zone-filtered busboard. Together, they provide a clean and stable power solution, capable of quietly delivering up to 3.5A on the +12V rail and 2A on the -12V rail. Ripple and noise are exceptionally low, even near full capacity, significantly outperforming typical off-the-shelf “can” switching supplies. Be sure to check out the User's and Installation Guide for more details and specs.
Modern Power for Modern Systems
As microprocessor-based modules have proliferated in Eurorack, the power requirements for many users’ systems have become more and more asymmetrical, relying more heavily on the +12V rail. The Eurobus system addresses this, and provides a very robust +12V rail (+3.5A) as well as an optional +5V (1.5A) rail. Note: this configuration includes the +5V option on both busboards for a total of 3A.
Modular by Design
The Eurobus’s modular design not only makes it one of the most flexible power solutions available, it also enhances performance. By utilizing the full width of the busboard for thicker traces and uninterrupted ground planes, routing and return paths are optimized- reducing impedances, improving power delivery, and lowering noise across the board, all while maintaining a compact footprint. One of the primary design goals for the Eurobus was optimal noise performance- approaching that of a linear power supply while retaining the benefits of modern switching efficiency- more juice, less heat, smaller footprint.
Expandable - 6U and Beyond
The Eurobus offers a scalable power solution for modern Eurorack systems, easily adaptable to a wide range of setups. The Eurobus busboard can be configured either actively or passively, used in conjunction with another active Eurobus, and upgraded with an SWB65 upgrade kit at any time for an expandable power solution that scales with your needs.
DIY'Y
Note that installation requires some familiarity with tools and techniques, but it’s manageable with a bit of planning. Retrofitting an existing case with our power supply should be straightforward, as you can likely reuse existing parts such as the DC brick, wiring, power switch, and DC input jack. You may not need to drill new holes for our mounting pattern (see the User's and Installation Guide for details). When installing into a new case, some planning is required to determine the best locations for power entry and other elements, so take your time. If you have questions or need guidance on selecting the right power supply, feel free to email us for a consultation—we’re happy to assist.

How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK it's normally around £4 for order values under £150, and free above that. Shipping to mainland EU is typically between £7 and £20, depending on the shipping method and the size and weight of the order.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of Parcelforce, DPD, Royal Mail and UPS for the UK, and for international orders it's either Royal Mail, UPS, DHL or FedEx depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we normally dispatch the same working day if we get the order before 15:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes FedEx or UPS may come a little earlier than scheduled which would also push an order into the next day.
Shipping times
Since April 2020 the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer.
There is absolutely nothing we can do about this unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
Saturday shipping
If you're in the UK and you order before 15:30 on a Friday then we can send something for a Saturday delivery (NB: this applies to UK mainland addresses only). The success rate with DPD is about 95% so it's worth a punt most of the time. Please note that if you select Saturday shipping on an order placed earlier in the week, we'll wait until Friday to ship it.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
