Sinometer HY3005D Variable Linear Lab Power Supply 0-30V 0-5A Reviews
This review is from: Sinometer HY3005D Variable Linear Lab Power Supply 0-30V 0-5A (Misc.)
Works as described. Great price. Be careful to avoid cheaper switching power supplies as they may overheat or burn out electronic devices. This unit is not a switching PS. You can get test leads in a variety of configurations that fit this unit from Radio Shack - inexpensive.

This review is from: Sinometer HY3005D Variable Linear Lab Power Supply 0-30V 0-5A (Misc.)
The controls are a bit difficult to adjust finely (despite the 'fine' adjustment pots) and there's some threshold where internally a relay clicks on/off which changes the ranges (adjustment is not smooth).
There is no voltage sense line, the green connector is an additional ground.
If the current draw doesn't vary much regulation works fine and there's not much ripple or other noise on the output.
The built in meters are adequate but low-res enough to want to use a good external meter if you are measuring milliamps or millivolts.
All in all a fairly low end supply but adequate if you understand the limitations. Good value for the price.
