DC Voltage Regulation
My battery bank is nominally 12V, but it will vary a lot based on what my solar charge controller is doing. I have a Co2 detector that is designed with a 110 AC wall plug that converts power to 12V DC to run the device. I don't have any idea what will happen to this thing if I try to attach it directly to my "12 V" batteries. I don't want to run the power through an inverter and back through the device's transformer. Is there a device that can take 12-15V variable power and deliver a consistent 12V?
