Accessory transformer used for Victory Glass wireless wallbox transmitters when hooking up some wallboxes – not needed for receiver in jukebox. For Export European use that has 220 and 240 volt wall power.
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.
