LF3-400 – Bench-top Frequency Converter – Magnus Power

Power Products

The LF3-400 Bench-top Frequency Converter offers a competitive price, fixed frequency, fixed voltage sine wave output ideal for aerospace/avionics applications.

A transformer ensures full isolation between the output voltage and the incoming supply and the output neutral (star point) may be earthed externally if required. The unit is fully protected against overcurrent and overtemperature conditions. Input power and output cable supplied. This unit is normally supplied as a free standing bench top unit; but the LF3 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.
