DC-DC Converters

Victron Energy's DC-DC converters are useful if you do not have a suitable voltage device. Available in Isolated and non isolated versions. 

Isolated & Non Isolated - Whats the difference?

Isolated DC-DC converters are generally more expensive they have strong noise and interference blocking capability thus provide the load with a cleaner DC source which is required by many sensitive load therefore gerat to use with Communications, Entertainment & Navigation Systems. 

Non-isolated DC-DC converters are common and of lower cost , they are used in most negative ground applications in vehicles for various DC powered appliances and equipment. However they have one big disadvantage in the electrical connection between the input and output which offers little or no protection to the load for any high electrical voltage , current and etc occurs on the input side. They also have less noise filtering.
