QHYCFW3 power supply

[NAG]

 
Connecting the QHYCFW3 to a external power supply, I believe the minimum voltage it's 12v ( or can be less ?). Can i connect it to a 13.8V power supply?
About the amperage, wath's the minnimum working amperage ?

Thank you very much

OK, working with 12v and 1 amp.

But now i have a problem. If i turn on the computer without power on the 12v power supply (filter wheel connected only from USB), i hear a loud noise. I think it's the motor trying to run but it can't due low power supply. It's normal ?

Hi,

Yes, it is normal.

When you use the USB cable to control the filter wheel, you may encounter the inability to control the rotation of the wheel due to insufficient power supply of the USB port. In this case, please increase the external power supply of the filter wheel. This power cord can be found in the accessories.

Hello, I have the wheel connected through that power cord and so far it works very wel.

My "problem" it's that every time i need to turn on the computer in my observatory, i have to be sure to power on the equipment before turn on the computer or i hear that noise. But if it's normal, no problem at all
