HIGH-POWER DC Blocker Assembled in a steel case with C14/C20 AC Inlet and double US-type AC Outlet

Description

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 (https://sound-au.com/articles/xfmr-dc.htm).

Here is offered device capable to handle VERY HIGH CURRENTS (up to 30 Amperes intrinsic current handling!!!) 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

Note that the Blocker undergone a redesign and now it has 6 discrete diodes which allows it to block DC shifts up to 2V!

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 or Schurter C14 IEC inlet, capable to handle 10A.

There is one double Hubbel/Pass & Seymour US-style AC outlet (medical grade, gray color) located on the front panel along with the IEC AC Inlet.

The customer can chose between Schurter C20 or C14 IEC inlets.

There are 4 rubber feet on the bottom of the case which ensure that case will not scratch the underlying surface.

Unit’s weight: 3 kg.

What the buyer will receive:
The package will contain 1 pcs. FULLY ASSEMBLED and tested HIGH-POWER DC trap/blocker/filter for toroidal transformers (toroids) in steel case.

The unit will be shipped with Priority AirMail Registered (or equivalent courier service where applicable). The tracking number will be sent to the customer after shipment.
