RIGOL Technologies, INC. released its new DP800 non-A series (DP831, DP821 and DP811) programmable DC power supply on July.1, 2015. Compare with DP831A, DP821A and DP811A, DP800 non-A series are simplified version with higher performance-and-price ratio, and they also can be upgraded by installing options. These new simplified models enriches the DP800 series product line and will brings more choice to customers.

DP800 series provides four models before: DP832A, DP831A, DP821A and DP832. Among which DP832 is a simplified version of DP832A. DP800 provides pure output, excellent performance, various analysis function and abundant interfaces which can meet different testing need.
The main differences between DP831/DP821/ DP811 and DP831A/DP821A/DP811A are programming resolution, display resolution and readback resolution. Besides, the standard communication interfaces of DP831/DP821/DP811 do not include RS232 and LAN, but they can be updated by ordering and installing options. The following table shows the options of DP800 non-A.
The new DP831 includes three channels: 8V/5A, +30V/2A and -30V/2A; The new DP821 includes two channels: 60V/1A and 8V/10A. While DP811 provides one channel with two output ranges: 40V/5A and 20V/10A..
