With one channel isolated users can reconfigure instruments into any number of systems or applications. Built in V, A, and W measurements make power monitoring easy, but additional wave tracking, timing, and analysis features in the advanced "A" models means there are even more ways to use the instruments. Digital triggering between instruments also makes it possible to reliably combine and connect supplies together. Intuitive to use for everything from education labs to the R & D bench, the DP800 family of power supplies provide incredible value for any application. Select the value models for best price performance or upgrade to the "A" model to improve resolution and add advanced monitoring, triggering, and programming capabilities.
