Powering my QHY183C with 13 volts

Powering my QHY183C with 13 volts

I have two questions.

My power system supplies 13 volts. Can I supply that voltage to the camera QHY183C?

Is there a relationship between the noise produced by the sensor and its voltage? There are sensors that produce less noise when using 13 volts instead of 12v.

You can use 13V, but there may be a risk of diode breakdown because the instantaneous voltage when plugged into the power supply may be higher.

There is no relationship between noise and voltages.Generally,the lower the temperature, the lower the noise

Your camera should allow a guaranteed maximum voltage of 13.8V because that's the typical voltage of a 12V car battery.

Actually, depending on the battery chemistry, the 13.8v is a float voltage. The charge is around 14v or 14.6v
12v batteries are nominal 12v.
12v Battery operated devices usually have a range of about 12v to 16v
