## Questions & Answers

**Q: Can this be an isolation transformer by disconnecting the ground on the transformed side?**
A: No. An isolation transformer requires primary and secondary windings so the winding returns can be connected to the desired ground. A variac (auto transformer) only has a primary winding so input and output share a common return. If you did not connect the source return to the variac ground no source AC current would flow.

**Q: Will this unit increase 1 volt increments? Thanks**
A: yes it sure will :-)

**Q: Has anyone tested the max input voltage?**
A: Hi there, 

Thank you for your questions. 

The TDGC2-2D maximum input voltage would be 120VAC to 125VAC 

Best regards.

**Q: Can I connect a 120v 1500 watt ceramic heater to it, will this device stop power overload?**
A: Yes you can connect a 1500W heater to this variac assuming the outlet you plug it into can provide 1500W and you set the output voltage to 120 V or less. You can reduce the power drawn by the heater to less than 1500W by reducing the voltage to less than 120 V.  The power drawn by the heater is: P=V²/R so reducing V reduces power.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Quality product. Functions as expected
*by R***K on January 1, 2022*

I like the digtal voltmeter for precisely setting the voltage and the precise settability. I purchased this unit to boost the output voltage of some of the battery powered power stations that typically output 110V AC.

### ⭐ Waste of money. Started sparking and then flew the fuse after about three uses. Not reliable.
*by D***H on October 30, 2024*

The first two months I owned it was off-gassing paint fumes or something so nasty that I had to leave it in the garage. After that I was able to use it. Third time hooked it up to a test load that wasn't drawing much current, but the wiper or whatever inside started sparking and shorting out. It blew a fuse. I don't plan on using it again. A total waste of money. I'd return it but of course it's out of warranty and past the return period.

### ⭐⭐⭐⭐⭐ Great!
*by G***7 on May 25, 2022*

Really nice Variac, well made and very accurate.
