High Output - Reliable Workhorses! The CV425 is an industrial power source designed for heavy duty applications. Power source meet IP23 protection which means that they will operate in in the most arduous environmental conditions experienced, in such places as shipyards or offshore yards. The machine has been designed so that all the sensitive components are enclosed in a compartment free from dust and separated from the air flow needed to cool the machine.
