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.

And we have well-proven guidelines for reducing safety/other risks that could be caused by EMI.

New 2018: Keith Armstrong's training courses 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This way of learning good EMC design is better than buying textbooks (which are out of date for years) or attending annual training courses (where most of the material is the same as the year before, you can't simply attend the new or improved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).

The IET’s Code of Practice on Electromagnetic Resilience
First published February 2017, the successor to the IET’s 2013 guide:
“Overview of techniques and measures related to EMC for Functional Safety”

Keith Armstrong's textbooks 
(Note December 2017: this is the new site for ordering these books)

These are colour-printed 'on-demand'. They are not available new from Amazon or other resellers,
who might mistakenly list them as being "out of print"
