Welcome to Cherry Clough Consultants

We are independent consultants who help manufacturers, system integrators, installers, and users deal quickly and cost-effectively with interference (EMI), and comply with the EU's EMC and Safety Directives and similar regulations. All applications, all industry sectors, worldwide.

Our very well-proven SI, PI & EMC design techniques help you significantly reduce 
design / development time and cost, overall cost of manufacture, warranty cost, and financial risk.

We also have well-proven guidelines for reducing functional safety risks, or other risks, that could be caused by EMI.

NEW: Keith Armstrong's training courses now available for on-line purchase
Anyone who buys a course module will be automatically updated with new versions for free, for some number of years (we haven't decided how many yet). The updating versions will be complete, with change records so you don't have to scan right through them to find the updated material.

This way of learning good EMC design is better than buying textbooks (which are out of date for years) or attending annual training courses (where most of the material is the same as the year before, you can't simply attend the new or improved material, and you have to pay full price again).

A new site for easy and free access to the huge range of Keith Armstrong's published material, and a lot of additional stuff such as EMI Stories, EMC Design Checklists, Webinars, and more.
