ReX 2 Jeweller with a standard power supply unit operates off 110-240 V~ mains.
To connect ReX 2 Jeweller to 12-24 V⎓ circuits replace the standard power supply unit with a 12-24V PSU (type A).
12-24V PSU (type A) is required to connect the range extender to the power system of a car, trailer, yacht, or an external battery/power supply.
To connect ReX 2 Jeweller to 6 V⎓ circuits replace the standard power supply unit with 6V PSU (type A).
6V PSU (type A) is required to allow the range extender to run on an external battery for years — without being connected to the facility’s electric power system — and be ready to protect run-down or empty premises as well as buildings under construction against burglars, vandals, or unauthorized occupants.
You can calculate the run time of ReX 2 Jeweller from an external battery using a calculator.
