Description

The DP821A have two outputs: one capable of 8 V and 10 A, the other makes 60 V and 1 A for a total of 140 W. Source flexibility allow 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.
