Accessory transformer used for Victory Glass wireless wallbox transmitters when hooking up some wallboxes – not needed for receiver in jukebox.
One transformer can power multiple transmitters and wallboxes. If your wallbox already has a 24vac supply or you plan on using one you already have you do not need to purchase this. The jukebox receivers do not need a power supply as that is derived from the jukebox itself in most jukeboxes.
