The DC Power Box is designed as a inline box to clean up and filter switching and linear power supplies. It has specific high freq filtering for cleaning out the hash from switching supplies along with plenty of extra filtering for smoothing out low frequencies rumble.

This DC POWER BOX works with our CC PSU 1 for a number of different projects. Use the DC Power Box to help clean the power to your DIY 500 series racks, Radial 500 series racks, preamp projects or any number of other projects.

Connection in and out of the DC Power Box are through 5 Pin XLR’s.
(5 pin XLR cable not included)

Standard Pinout: (If you specify a different pinout we can accommodate that.  Radial uses a different pinout for instance. )

  1. Pin1 = SHELL:FG
  2. Pin2 = COM
  3. Pin3 = +16v
  4. Pin4 = -16v
  5. Pin5 = +48v

Our real world test:
We tested a CAPI 500 rack with 5 modules installed for a real world load powered by one of our CC-PSU1.  The DC Power Box gave us 10db in noise reduction and really smoothed out the ripple.  Well worth the effort.  These kind of results will give you a solid clean power rails that will help the gear you have really shine.
