Rigol DP821(A) Programmable DC Power Supply, 2 Channels, 140W

The Rigol DP821(A) power supplies combine the ability to source, analyze, and coordinate over time in a powerful package. The linear power supplies have 2 outputs and up to 140 W in total. 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 means there are even more ways to use the supplies. New 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.
