Roland Ledyard explains how 0-10V and digitally-connected LED drivers differ in functionality, and how those differences are manifested in commercial solid-state lighting installations. ROLAND LEDYARD explains how 0-10V and digitally-connected LED drivers differ in functionality, and how those differences are manifested in commercial solid-state lighting installations. One of the most persuasive words in marketing has got to be “free,” despite the fact that we generally know that nothing in life is truly free, especially when it comes to LED drivers. Dimming functionality in drivers, implemented based on 0-10V controls, is sometimes touted as free, but in reality nearly every technology decision has a cost associated with it. Read along to learn about the issues with 0-10V LED drivers that can lead you to optimal selection and understand how more-robust digitally-addressable drivers may ultimately prove more economical in an actual solid-state lighting (SSL) project. The adage that nothing truly comes for free is certainly true for 0-10V LED drivers. Many 0-10V LED fixture manufacturers offer dimming drivers as a no-cost upgrade versus what we will call switching dr...
