Review: Does the job, uses 8.1W - Works as described. Includes a plug-in power supply but not the wires to connect the damper to the supply. The device is NOT UL or ETL listed (only the power supply is). When open the device consumes no power. When closed I measured a power consumption between 7.9W and 8.4W (8.1W average).

## Questions & Answers

**Q: "24V Hardwired power supply included" - Does this take 24v input or does it take 110v input and provide 24v output?**
A: 110v input
24v output

**Q: Can this be controlled from a switch to varying angles?  Or is it just 'on' or 'off'?**
A: No because the spring will revert it back to open position as soon as you shut off power to the motor.
In order to do what you want you will need to get a motorized unit powered to to open n close unit without a spring return option.

**Q: Trying to give this its own switch what is the plug called from the transformer to the dapners?**
A: There is no plug. Hardwired.

**Q: Can i hardwire this to a timer to close and open at set times?**
A: I would imagine that it would work only if the timer can pass the required voltage to turn the motors (24V).

### ⭐⭐⭐⭐ Does the job, uses 8.1W
*by J***S on 11 July 2024*

Works as described. Includes a plug-in power supply but not the wires to connect the damper to the supply. The device is NOT UL or ETL listed (only the power supply is). When open the device consumes no power. When closed I measured a power consumption between 7.9W and 8.4W (8.1W average).

### ⭐⭐⭐⭐⭐ Made in the USA!
*by T***. on 27 April 2021*

Work great, cheap price and made in the USA

### ⭐⭐ Needed Modifications Right Out the Box
*by R***L on 22 August 2018*

I haven't installed these yet and therefore haven't used them but I did wire them up and test them. After some needed modifications right out of the box I think they should work fine. I bought three of these 8" normally open. On all three of them, when the damper was fully closed the damper did not seal with the foam seal properly. There was anywhere from 1/4" to almost 1/2" gap between the foam seal and damper. I was concerned with a gap, there would be a whistling sound due to the air flowing through the gap when the HVAC was on and the damper closed. I ended up pulling off the foam seal, applying some rubber cement and moving the seal into a better position that created a proper seal between the closed damper and the foam material. Now there is no gap. It wasn't much work to do it and I think it'll hold but no product should need modifications right out of the box to work properly.
