Description
The DP821A has two outputs 60V/1A and 8V/10A with Remote Sensing and total power of up to 140W. Source flexibility allows users to reconfigure the DP821A be used in many systems or applications. Built in V, A, and W measurements make power monitoring easy, but additional wave tracking, timing, and analysis features allow for greater application flexibility. New digital triggering between instruments also makes it possible to reliably combine and connect supplies together. Intuitive to use, the DP821A is ideal for educational applications, lab, R & D and bench use.
