## Description

Product description 3 Amp Variable Transformer WARNING 300 VAC Max, 0-130V Output This variable transformer is a great device for quality control testing, equipment testing on low and high voltage, control over heat, speed, and more.

Review: Best fan speed control ever - I bought a cheap one of the cheaper "Active Air" fan speed controllers for my 4" in line fan. Although the fan speed controller worked as advertised, I could tell the fan motor was under some strain. The fan struggled to start up if the speed was dialed down, and operated with a noticeable "buzz" or electrical hum. I did some research and saw that the in-line fans operate much better with a Variac variable transformer. Wow, what a difference this unit makes. My fan now starts slow and smooth, and runs with no strain on the motor at all. No "Buzz" no electrical hum. The only sound made is the air moving through the duct work. The volt meter on the front is an added bonus as well. I can tell exactly how my fan is doing at a glance.
Review: Works as expected. Great little unit. - I bought this to control the speed on one 6 inch inline fan. It has been running for 24 hours per day at just under 50%. I have not seen any issues with the variac, It is not even warm to the touch.The fan is not laboring or making any unusual sounds. I was unsure before purchasing, that it was the right choice for my application after using another type fan speed controller that failed. So far it has been flawless and would recommend to any one wanting to slow the speed of a fan. I have not tried to use it controlling two fans as the rating is 3 amps. If I purchase another it would be a larger amp rating.

## Features

- Input: 120 volt AC, Output: 0~130 volt AC, 3 Amp Slow Blow Fuse
- Max VA: 300VA, 3 Amp. Max (surge)
- A rating of 300VA means that at 100volt, the unit can sustain at maximum 3amp. If at 120 volt the unit can sustain at 2. 5amp
- WARNING: Most devices have a surge amperage (when first turned on) that is much higher than the device's operating amp rating.
- EXAMPLE: A motor with a 3 amp rating may have over 5 amp surge, and you will need a 5 amp variable transformer

### ⭐ just not very sturdy.

I used this one time, it was then knocked off of a 2 1/2 foot shelf and ceased to function. It works as advertised, just not very sturdy.
