Rigol DP832(A) has 3 channels.
- Ch1 is floating, galvanic isolated from the other two channels
- Ch1 can be used either in series (either with + or with - in series with Ch2) or in parallel with Ch2
- Ch3 and Ch2 have internally wired common GND, but Ch3 can go up to only 5.3V, Ch1 or 2 can go up to 32V each
- Any of the 3 channels can give max 3.2A, analog PS, 1mV, 1mA, SCPI, LXI, etc.
- Ch1 and Ch2 can be put in following mode if needed, over current prot, over voltage prot, etc. (protection values are another setting, distinct from setting the generated V in CV mode, or generated I for CC mode). OVP and OCP are software driven (they have a small delay, and when triggered, the output channel is turned off).
- Series mode is made by properly connecting the wires (manually) outside of the PS.
- The PS has sense wires (leftover from another model), but they are only used internally, tied inside the PS, no sense wires are available outside of the PS
- Any of the 3 channels can only be used to supply power (they can act as a load). However, with this trick it can still be used as a controlled load to measure batteries and such:
