Review: Great - Works and it's cheap. I'm an engineer and it does what it says
Review: Superb piece of kit - Brilliant power supply for the money. As others have reported the fan comes on very quickly on constant current even at very low currents and is a little noisy but it's a minor point really. Also the supplied alligator plug leads are quite short, so I bought a new longer set and now use the originals with my multi-meter. This has been so useful in testing/diagnosing and repairing electronic items and projects. I should have got this years ago! If you're getting into electronics building or repairing this is a great first bench supply.

## Questions & Answers

**Q: 1.When I power it on, the current displays show zero, is it normal?**
A: If it isn't connected to a load it should read zero because no current is flowing. This DC power supply requires manual current and voltage settings.

**Q: 2. How do I get it to stay in constant current mode?**
A: CC is attained when the rated set current is exceeded. It would stay in that mode till the current drops back to the preset.

**Q: 3.How to set the current value without load connecting?**
A: Please short the +/- outputs together, set the current, and remove shorting cable.You could also refer to the operation instruction.

**Q: 4.Does it remember the last settings when turned off and back on again?**
A: Yes,because it's on a dial.If you don't adjust it and just flip the on and off switch in the front it will remain the same.
