These adapters provide a controlled 12 Volts at 5 or 10 Amps for supplying power to the TEC cooling system of any ZWO cooled camera or the ASIAIRs.
Please add this option if you are buying a ZWO cooled camera, ASIAIR or ZWO mount and don't have a 12V power supply.
Great for any astronomy component that requires a regulated 12V power supply.
The connector is a 2.1mm x 5.5mm power jack, positive centre.
