The Ajax 6V PSU (Type A) is a specialized power supply board designed to let you run your security system from a low-voltage external battery instead of a standard wall outlet. It is fully compatible with the Hub 2, Hub 2 Plus, and ReX 2, replacing the factory 110/230 V power unit directly inside the device enclosure. This board accepts an input voltage between 4.2 and 16 V and converts it to a stable 4.8 V output with a maximum current of 1.5 A, ensuring your equipment receives consistent power. Measuring 98 × 70 × 17 mm and weighing only 26 g, the board is compact enough to fit seamlessly within the existing housing. It features a 6.5 x 2 mm socket and a 5.5 x 2.1 mm plug for secure connections. For the best results, you can use zinc-air or alkaline batteries. The system is built to operate reliably in temperatures from -10°C to +40°C and humidity levels up to 75%, making it a dependable choice for those who need to maintain security in locations without permanent electrical wiring.
