## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Well-built supply - but grounds are not isolated.
  

*by S***Y on Reviewed in the United States 🇺🇸 on July 16, 2016*

This is a good isolation transformer - but it is not "laboratory grade" and does have the incoming ground connected to the outgoing ground.I needed a nearly totally "floating" supply for my testing with an oscilloscope where I was measuring current across a resistor - so I used a "cheater" two prong adapter and I put "bleeder" resistors from common to ground so that the supply did not "float" too high. (If you are in electronics, you know what this means).And for my purposes, that worked.Construction looks good - I took it apart and checked.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Product miss-information !!!
  

*by M***G on Reviewed in the United States 🇺🇸 on July 9, 2020*

Output voltage measures 134 volts with a 120 volt input.Nice package, nice size and weight, but if the output voltage is critical to you, give it some thought.Maybe at full load of 1.5 amps the output voltage may drop to 120 volts ????

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    works as expected
  

*by M***H on Reviewed in the United States 🇺🇸 on March 22, 2022*

remember the third pin is connected ground both input and output sides.
