This IP67 mains power supply can be built into the GX2 12V and the GX2 DMX, replacing the internal lead-acid-battery. It allows for the use of 100-230V AC mains power, as a power supply for the Gasprojector. With the mains power supply, two powerCON-sockets are built into the Gasprojector (Input and output). This allows you to connect multiple devices with the mains power supply to eachother.
