Rigol DP932U Programmable, linear DC power supplyThree electrically isolated, independent channelsOutputs: 32V/3A; 32V/3A; 6V/3AMaximum total power: 210WDP932U is the “University” model and has less standard features than the DP932A Three Channel Programmable DC Power Supply (University Model) DP900 Series Power Supplies combine Rigol's new touch screen interface with new flexibility and higher speed functions designed for benchtop DC power analysis. These provide three electrically isolated, independent channels with a maximum total output of 210W.The chart below provides an overview of the main differences between the three models in the DP900 series.
