These “UP” converters produce 24 volts from 12 volt systems and are ideal for 
managing dual voltage applications on marine vessels without having to install a 
24 volt battery and dedicated charging system. Choose from two types depending 
on your application:
In the Standard, 
Non-Isolated Series the 12V input and 24V output share a common 
negative ground and are ideal when installing certain electronics that operate 
better on 24 volts when a robust 12 volt system exists. Models available in 
outputs of 7, 16 and 25 amps.
The Isolated Series allows 
compatibility between positive and negative ground systems, for example 
installing negative ground 24V electronics on a 12V floating ground aluminum 
vessel. The isolated series is also a good choice for dual voltage system where 
noise and interference is an issue. Its input/output partitioning circuit 
prevents noise on the 12 volt system from being transmitted to the 24 volt side.
