RigolDP832A Programmable Linear Dc Power Supply,3 Channels,195W Total Power,Maximum Output Range 30V/3A || 30V/3A, 5V/3A

Not much else to say... the DP832A is a solid bench power supply with all the features you'll likely need in daily use, and provides great value for the money.

very nice bench power supply. easily set, programmable with computer interface. Only drawback is the output of channel one and two cannot be set to 0 volts. Was not calibrated properly and when seller was contacted 3was told it's within tolerance. I have 2 $40 power supplies on the same bench, both can be set to 0 volts, why not a $600 linear supply.

This is a pretty good bench supply, quiet and accurate. Two comments: only the left most supple actually floats. The right 30 V and the 8 V supplies have their negative output tied to earth ground. If you know about this, you can usually work around it, but it will not generate +/- 15 at +5 . This also makes the supply prone to making ground loops. The other modest issue is the odd human interface. It does support tracking mode, but it is buried in the menus and has ill-defined cues as to which supply controls both. The displays are ordered in a circle, not linearly like the outputs. The numeric keypad is a circle around the large knob. The supplies are not vividly color coded to the display colors. So technically it is a fine supply, but it is in drastic need of a user interface upgrade. I really expect a “lab bench” supply to give me floating supplies. Nothing else comes close to it’s performance for the price.
