Description

The DP831 Power Supply Series combine the ability to source, analyze, and coordinate over time in a powerful package. The DP831A has plus and minus 30 V channels at 2 Amps and one 8 V, 5 A channel. 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.
