Power Supply 

SeventyPWR has 70W of output power (+12V / 2500mA, -12V / 2500mA and +5V / 2000mA). The design is based on the more powerful HammerPWR PSU with few upgrades.

SeventyPWR PSU is targeted to all who want enough power, low noise, high efficiency, best filtering, and a high level of power stability and secure protection for all modules in the Eurorack case.

The narrow shape of SeventyPWR allows it to mount between two bus boards. A double output terminal connects wires separately to two (or four) bus boards. This minimalizes the wire length and impedance of the power network. SeventyPWR works perfectly with all standard bus boards.

A special feature of SeventyPWR is the possibility to adjust output voltage in a safe range. Output voltages +12V and -12V are factory adjusted with an accuracy of 0,1% or better. Adjusting features can compensate for voltage drops on wires under load. This feature allows setting very accurate voltage directly on the module’s power inputs.

As is our practice SeventyPWR comes with overvoltage, over temperature, over current, short current, overload, and input reverse polarity protection. There are two stages of input filters which decrease noise from power brick and the electrical grid.

SeventyPWR is safely + externally powered from a 90W power brick (Meanwell GSM90A19-P1M – sold separately ) to make sure you and your modules are safe as well under all conditions. The inlet panel with connector and switch comes with PSU as basic accessories.

SeventyPWR ideal choice for any system including skiff and DIY where depth and size can be your concern.

Easy to install the push-to-connect system – WAGO 256 series shockproof + push-to-connect terminals ensure easy installation of SeventyPWR within your case.

Power Supply 

HammerPWR is a reply to requests from users to provide a definite eurorack modular power supply that would be able to sustain and protect the most “busy” of setups. This eurorack modular power supply is developed to provide stable and clean power and further address many of the intrinsic topics which plague the daily eurorack modular musician.
Why name HammerPWR you ask? It is quite simple. It packs a powerful 100W unit with an output that can supply enough juice to the most hardcore eurorack system out there. Two of these will get your eurorack modular system rig going for a lifetime.

HammerPWR is  a strong eurorack modular power supply meant for use in the hardest of conditions on the market featuring the highest power density money can buy. The ideal solution for the largest of systems featuring many power-hungry analog/digital modules or modules which draw a lot of current needed for their ensured smooth operation. The system of filtered protection on the inputs and outputs of the power supply stays in place with minor tweaks to its core design making sure that your system will keep operating under hassle-free, low-noise, artifact-free conditions while also being protected from noises present in the power grid at times so your system and modules are safe and intact from external occurrences, mishaps, and influences. To ensure the lowest possible noise within your system there are a special type of converter used with low noise on their outputs and the +12V / 5A line is split into two branches by 2,5A + 2,5A to further decrease inherent influence between modules. Two sets of output terminals then further elevate the stress of cables connected to the bus board for longer service life.

HammerPWR is safely + externally powered from a GST120A20-P1M ( sold separately ) to make sure you and your modules are safe as well under all conditions.

The small dimensions of HammerPWR make it an ideal choice for any system including skiff and DIY where depth and size can be your concern.

Easy to install the push-to-connect system – WAGO 256 series shockproof + push-to-connect terminals ensure easy installation of HammerPWR within your case.

We all know how popular the RT65b Meanwell PSU is in the world of DIY eurorack cases. Everyone who ever worked with this PSU knows that unfortunately, it has all the screw terminals exposed. Leaving the screw terminal connector uncovered creates several risks.  Firstly, it can lead to unintentional short circuits. Secondly, you are risking damaging the expensive modules if they come in contact with high voltage AC connectors. Thirdly, and most importantly, contact with high voltage AC can cause personal injury.
Therefore we decided to come with a solution to this problem! We have designed and manufactured a terminal cover that fits the RT65B Meanwell PSU perfectly!

RT65B Screws Terminal Cover Details

• • Our Mean Well RT65B Screws Terminal Cover is super small. It doesn’t take any additional space in your eurorack case. The entire screw terminal cover fits within the contour of the PSU housing. Most importantly, the cover is small enough that it doesn’t cover terminal descriptions. Therefore you will clearly see which wires conduct AC or DC voltages.
  • Installation is super easy. It doesn’t require any drilling or gluing. All you need to do is to remove one screw from the PSU, slide the screw terminal cover in place and secure it in place with the replacement screw that we supply.
  • We build our Mean Well RT65B Screws Terminal Cover from bright orange plastic. Therefore visually you won’t miss the fact that you put your fingers or modules close to the power supply.
  • The main purpose of the screw terminal cover is to not allow contact with the connectors. However, it doesn’t mean you can be careless with the installation! Remember that you work with high AC voltage! All connections must be made in accordance with the standards for proper insulation of electrical devices. If you are unfamiliar with the subject, hire a specialist to do it for you.

ATTENTION!

Assembly and connection of any parts leading mains voltage (e.g. mains inlet, power supply board, cables) are allowed only by qualified personnel who are familiar with the applicable safety regulations! For a layman, it is strictly forbidden to carry out such assemblies or connections!
All parts that lead mains voltage (wires, PCB tracks, electronic parts) have to be fully isolated against damage to the device before the unit is powered so that accidental contact with these parts is not possible! Otherwise, there is a danger to life!

We recommend Meanwell GSM60A18-P1J DC Power Brick for one BoardPWR PSU and GST120A20-P1M for two BoardPWR PSU solutions.

Connectors

There are two types of output connections. You can either connect bus boards via two 16pins IDC headers (ideal for flying bus boards) or via high-quality WAGO spring terminals.

Use our 2.9 x 13 mm screws. With standard 1.6 mm thick PCBs use 3 mm long Standoffs to get 8.4 mm long threads left that will go inside mounting surface.

Mounting surface is less than 10mm thick?

Use our 2.9 x 13 mm screws. With standard 1.6 mm thick PCBs use 5 mm long Standoffs to get 6.4 mm long threads left that will go inside mounting surface.

We recommend those Bus Board Standoffs when you are using our Filter Bus Boards or Power KITs.
