AC Mains DC-Blocking Board - Assembled or DIY Kit

Choose a DC-component blocking board for an appropriately engineered AC power project. This selection offers an assembled board or a kit requiring soldering.

✅ Add a targeted filtering stage - The circuit is intended to address a DC component in a matched AC supply design.

✅ Choose assembled or kit format - The two options provide different preparation levels for the project.

A Specialist Board for a Complete Power Design

Transformer noise can have more than one cause. A DC-blocking stage should only be selected after the actual problem and circuit requirements are understood by a qualified person.

This is a mains-connected component board, not a plug-in power conditioner or a safety-isolation device. It requires suitable engineering, enclosure and protection. The KIT option needs assembly; the Finished board still needs a compliant installation.
