## Questions & Answers

**Q: Is the power supply UL Listed or just the power cord?**
A: Hello Customer
It is just the power cord has UL listed, not the power supply.
Thanks for your support.

Thanks for your attention us on Amazon.
Our 30V,5A 3 digital power supply precision from 0.01V and 0.01A resolution over the full range. We suggest you that to buy our 4 digital power supply can go down to 4mA.

Thank you.

**Q: The unit will not display any amperage, and, it stays at zero.  What do I do, or, is the unit defective?**
A: Hello Dear Customer
The knowledge of electronic is it will not display the amperage when the machine under the no-load condition, that means under the condition of without any load. Please take a look of below instruction of how a power supply works on Current?
With empty load
Current is unable to be regulated at empty load circunstance.
Current adjustment 
A limit current is usally needed when we work on some project. To set a limit for current, we have to first of all empty the load, turn down the voltage to the mimium, shorten the power supply, and finally turn the current knob both coarse and fine to get a desired value. 
Thank you for your support us on Amazon.

Regards
Pevono

**Q: How to enter Constant Current mode?**
A: The PS is weird to operate.  If you turn on a little voltage and then turn up the current, it will be in Constant Current, vice versa, a little current and turn up the voltage, it is in Constant Voltage.  The manual is completely worthless.  If I had it to do again, I would get a supply that had a switch for the mode.  This one works fine, but it is very confusing.
