50Hz to 60Hz / 60Hz to 50Hz Frequency Converters

These frequency changers are designed to supply 3 phase alternating current (AC) critical loads with high stability 60Hz or 400Hz frequency from a 50Hz or 60Hz input power source. This compact dimensioned product is ideally suitable for applications in military and civil aviation, shore to ship services, avionics workshops, radar sites, where products from the USA are required to operate from 50Hz power supplies or when 50Hz equipment is required to operate from a 60Hz power supply.  

The frequency converter construction is based upon the standard rectifier and inverter sub-assemblies. Batteries can be added to the unit to provide autonomy and power security for users who need continous power at times when there is the risk of input main degradation or failure.

An optional mimic status and alarm panel with either digital or analogue metering can be provided on the front door of the frequency converter. A remote alarm interface facility is available as an optional feature.

We offer three types of units to support the different frequency and voltage combinations.

  • SFC40 : Supplies 3 phase AC critical loads with 400Hz frequency and voltage from a 50Hz or 60Hz input power.  
  • SFC50 : Supplies 3 phase AC critical loads with 50Hz frequency and voltage from a  60Hz input power.  
  • SFC60 : Supplies 3 phase AC critical loads  with 60Hz frequency and voltage from a 50Hz input power.
