EU Inverters Mostly Non-Compliant to EMC Emissions Requirements in EN 55011 and EN 61000-6-3

In the first half of 2014, the European Union’s EMC Administrative Cooperation Working Group (EMC ADCO) performed a cross-border EMC market surveillance campaign to assess the compliance of grid-connected solar panel inverters (and optimisers) intended to be used by consumers. Inverters allow electricity generated by solar photovoltaic (PV) modules to be fed into the mains... Read More

Environmental Testing – Like HALT – Improves Product Reliability & Ruggedness

Environmental testing has nothing to do with an evaluation of the earth’s environment.   Not the environmental testing we’re writing about here anyway. Also known as environmental simulation, environmental testing involves putting your electronic product through environmental extremes and then determining what hardware failures occur.   This process is crucial for pinpointing design flaws for ensuring the...

For New Technologies – Like 3D Printers – What Product Safety Standard Applies?

Product safety compliance for equipment that falls into an established product category is straightforward.  But what about new technologies – how are these products evaluated?  As a case example, let’s look at 3D printers.  3D printers aren’t new, but they are just now entering the mainstream, with many more manufacturers developing new small desktop versions...

GR-3160-CORE is NEBS Lite for Data Center Equipment

GR-3160-CORE, NEBS Requirements for Telecommunications Data Center Equipment and Spaces, is sometimes described as ‘NEBS Lite.’  It includes important reliability and safety requirements, without the full set of hurdles found in the NEBS telecom standards, like GR-1089-CORE and GR-63-CORE. But what exactly are the differences for equipment evaluation?  Following is a basic overview. The test... Read More
