Everything that you need for powering up of your case is included in one complete 100W SET. HammerPWR SET is the best choice on the market for big eurorack studio and traveling cases up to 12U with power hungry modules.



Konstant Lab Power SET is an ideal choice of power for DIY case builders. Everything that you need to power up your case is included in one complete SET. HammerPWR SET is the best choice for big eurorack studio and traveling cases.

HammerPWR SET – includes a small 100W power board (zero HP) (+12V / 5A, -12V / 2.5A, +5V / 2A), power inlet panel with switch, four Filtered bus boards – each of them has 18 output headers (6 filtered and 12 direct) which ensures that you will be able to power up quite a lot of modules, 120W Meanwell power brick, wires, spacers, and screws.

HammerPWR is a small but powerful and low weight PSU solution. You can mount it into your synth case without sacrificing any HP. HammerPWR is safely supplied from an external DC power brick (19-24V).

Filtered Bus Board is a low profile bus board with extra filtered output headers. Bus board contains 18 or 19 output headers (depends on what kind of bus board you chose). 12 (13) direct headers and 6 filtered headers with LC filters. Filtered headers are specially dedicated to feed analog modules that are sensitive/susceptible to power quality. Filters reject noise caused by PSU and digital modules by 70%. Each power rail is protected against over voltage so your modules and system are safe under all conditions. 90% of the bus board area has only 11mm with inserted connectors. This feature makes Filtered bus board an ideal power distribution solution for skiff cases where depth is a concern.
