LF1-400 3kVA

The LF1-3kW frequency converter offers low price fixed voltage single phased sine wave output. A transformer ensures full isolation between the output voltage and the incoming supply, and the output neutral may be earthed externally if required. The unit is fully protected against overcurrent and temperature conditions, LF1-3kW are supplied with input and output cables. This LF1-3kW is normally supplied as a free standing bench top unit; but can also be built in a rack mount configuration if required at no extra cost. 

A support shelf or bracket would be required when the rack mounting option is specified: these are not supplied with the unit, as their dimensions will depend on the arrangement of the cabinet or rack.
