Lectrosonics ISO9VOLT Isolated Battery Eliminator

General purpose isolated battery eliminator without door. Uses a high frequency converter and transformer to isolate power supplies and break ground loops. Typically used in bag systems to prevent ground loops when using a common battery supply. For matching doors with hole for power plug. The ISO9VOLT battery eliminator allows Lectrosonics wireless transmitters with hinged battery doors designed for 9 volt batteries to be operated from external power sources. 10 to 18 volt DC is converted to regulated 9 volt DC to power the transmitter at the battery terminals inside the battery compartment. The modified door exposes the connector for the external power source yet still operates with regular dry cell batteries. The unit can supply up to 200 mA to work with the 250 mW transmitters. It is fused and protected from reverse polarity. The unique design isolates the power ground from the audio ground in the transmitter allowing the unit to be used in "bag systems" common in field production.
