Product Details

Parts Express 10A Variac Variable AC Power Transformer 0-130 VAC

A variac is an extremely handy device that allows the user to dial 110/120 VAC wall voltage up or down from 0~130 VAC, measured by a meter on the front of the unit.

Most often, variacs are used on test benches, either to troubleshoot problems, test experimental circuits, or slowly power up vintage electronics to evaluate and perhaps recondition aging internal components.

They're also used in performing arts and cinematography to control lighting. In areas where line voltage runs higher than standard, use of a variac can improve the function and longevity of electronics.

• Current capacity: 10A • Dimensions: Overall diameter: 6-3/4"; Overall width including power switch, meter and outlet: 8"; Overall height including knob: 8".

Parts Express 10A Variac Variable AC Power Transformer 0-130 VAC
Parts Express 10A Variac Variable AC Power Transformer 0-130 VAC is rated 4.6667 out of 5 by 3.
Rated 4 out of 5 by from Works well, but dont trust the metersOn first opening the box, there is a heavy oil based paint smell. I posted on PE express site and was told this is normal. Do not rely on the voltage scale on the knob or the tiny meter on the Variac, because they could be off by a lot. Instead use a multi-meter on the second outlet set to read higher than 200v AC. When raising the AC, it is smooth and steady.

Rated 5 out of 5 by from Ease of useI used this product right away on a Hallicrafters S38A receiver. Operation was smooth as I increased the voltage over a five minute period. Like the "isolation" feature as this radio under test can have a hot chassis. Liked the fact two extra fuses were included for anticipated failure if needed. Good packing on shipment. Easy purchase, I like Parts Express.

Parts Express 10A Variac Variable AC Power Transformer 0-130 VAC

Received the 10A Variac yesterday. Removed it from the box and plastic bag and found there was a strong smell of wet paint. It smelled like oil based paint. Is this normal? Thanks. Vince

Asked by: Vincetronic
Yes this is normal for these.

are you sure the unit provides isolation? Most of these do not. 

Asked by: gramsey
The inherent design of a variac does not provide for isolation. It would have to have an internal isolation transformer to do that. Highly doubtful.

I need to order a replacement knob.  How should I tackle this? Thank you, Greg

Asked by: FRESH
We do not offer these knobs separately, although we may be able to grab one off of a returned unit if we happen to have some. Please contact our tech support for more help with this question, tech@parts-express.com or 800-338-0531 x1.
