HIGH-POWER DC Blocker Trap Filter – C20 IEC Inlet, 2 AC Outlets
HIGH-POWER DC Blocker Assembled in a steel case with C20 AC Inlet and two AC Outlet
NOTE!!!! This unit derives from the standard version with cable glands due to the numerous customer requests.
Nowadays the AC mains network is heavily polluted by various domestic appliances, industrial electrical consumers etc. This can lead to buzzy toroidal transformers (especially the power ones). Proposed DC trap (blocker, filter) will remove or at least lower the buzzing.
Schematic is similar to this one used in well known Vladimir Shushurin’s Lamm-1 amplifier. An article with in-dept explanation of how DC blockers work can be found on Rod Elliot’s site (http://sound.whsites.net/articles/xfmr-dc.htm).
Here is offered device capable to handle VERY HIGH CURRENTS (up to 30 Amperes!!!) assembled in a steel case – black powder coated.
Because of such high currents using a standard PCBs is not possible. Instead of that a 2mm. thick pure copper bussbars are used to connect the filter’s parts.
In order to carry such high loads the part’s values are upraised with 4 x 47 000 uF capacitors, 25W power resistor etc. For further description of the High-Power DC Blocker see here: High-Power DC Blocker Unit
The capacitor block is firmly connected to the bottom of the case with brackets and rubber sheet.
The input AC connector is Schurter C20 IEC Inlet, capable to handle up to 20A AC current.
There are two Schneider’s Unica Top series AC outlet located on the front panel along with the IEC AC Inlet. Each AC inlet can handle up to 16A AC current.
The customer can chose between EU Schuko, UK, US, French and Italian style AC Outlets.
There are 4 rubber feet on the bottom of the case which ensure that case will not scratch the underlying surface.
Unit’s weight: 2.50 kg.
