The Lectrosonics Battery Eliminator allows UM series wireless transmitters to be operated from external power sources. The Battery Eliminator resembles a standard 9 volt battery with an external power connector. This model does not include the specially modified battery compartment door and replaces the Battery Eliminator itself.
10 to 18 volt DC is converted to regulated 9 volt DC to power the transmitter at the battery terminals inside the compartment. The Battery Eliminator is an ideal tool while using UM series transmitters, operating on 9 volt batteries.
