### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great for tinkering / beginners.  Like me!
  

*by J***N on Reviewed in the United States on November 13, 2019*

I’m just a tinkerer, and I needed something safer than the way I had to use 2 cars ,2 sets of jumper cables, clamp on to screwdrivers just to get 24V.  So I’ve been using this power supply for about a week it does everything I need and I haven’t broke it yet, even though I have melted some wires, trip some breakers , but all in all I’ve had lots of fun and I’ve learned about electronics,  Only regret is I wish there was someway to reverse the polarity, without having to switch the wires around maybe there’s something for that?

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Might have a problem
  

*by J***G on Reviewed in the United States on February 20, 2021*

The power supply works, but seems to have some problems with the power switch.  Sometimes when I turn it on, there is no power at all or there is power but no controllable output.  The switch has to be toggled a few times to get it to work properly.  I may have to return the unit, because clearly there is something wrong that will affect its useful life.

    High frequency ripple every 17.5 microseconds!
  

*by D***A on Reviewed in the United States on March 4, 2019*

I have to revise my opinion of this power supply. I now have an oscilloscope. The voltage output has a high frequency ripple every 17.5 microseconds. The ripple is +- 0.75 Volts about the set voltage output. see photo. This definetly would not work for any sensitive circuits.before buying the oscilloscope I like the power supply in general.The on/off power switch is flakey. Sometimes it does not work. Have to hit it several times before it finally powers up. At this time I am assuming it is the switch and not the internal circuit.
