Frequency Converters

What are static Frequency Converters?

A static frequency converter (SFC) is a device that converts a fixed voltage and frequency to different voltage and frequency. They are used to power equipment which functions at a given voltage and frequency, such as aircraft or military equipment (115VAC, 400Hz), when the available power is, for example, UK mains (230VAC, 50Hz). SFCs, as opposed to older technology such as rotary or motor frequency converters, have no moving parts and are therefore more efficient and robust. They can also be used to convert from single to three-phase.

Standard applications for SFCs are commonly within the aviation industry; converting mains power (50/60Hz) to aircraft power (115VAC 400Hz). They are used to replicate aircraft power supplies when carrying out development, testing or repair-work on equipment installed within aircraft. This can be anything from system critical navigation equipment, through to commercial craft galley equipment such as coffee machines. 

SFCs are used with military and oil industry applications when power at 400Hz is required at either single or three-phase. They are also used within general electronics industry when an application requires conversion from 50Hz to 60Hz, or 60Hz to 50Hz with a single or three-phase output.

GB Electronics can provide a wide range of Static Frequency Converters; ranging from a basic single-phase fixed output 1kVA 115VAC 400Hz LF range machine to the three-phase ME range, which starts at 10kVA and increases to 500kVA. The input and output can also be customised for your bespoke requirements.

As the designer and manufacturer of the products, we can customise our design to suit your application. Another benefit of our ‘off the shelf’ fixed voltage products is that they are all easy to use, plug-and-play devices and very competitively priced.

LF1-400

115/200V 400Hz Single Phase output, at up to 1kVA

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 overtemperature conditions. Input power and output cable supplied.

This unit is normally supplied as a free standing bench top unit; but the LF1 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.

LF1-400 3kW

115V 400Hz Single Phase output, at up to 3kVA

The LF1-400-3kW frequency converter offers low price fixed voltage single phased 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, LF1-400-3kW are supplied with input and output cables.

This LF1-400-3kW 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.

LF3-400

115/200V 400Hz Three Phase output, at up to 3kVA

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 LF3-400 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.

ME Range

50-60Hz, 60-50Hz and 50/60Hz - 400Hz Static Frequency Converters

GB Electronic are pleased to announce the launch of the ME Range of Static Frequency Converters, the ME range come as single or three phase. Single Phase models are available from 10kVa to 30kVa and the Three Phase models are available from 10kVa to 450kVa. 

Our Static frequency converters have been designed to be environmentally friendly, reliable and easy to use, versatile in their construction with most voltages and frequencies catered for, for a specific quotation please call the number listed below or enter your details into our enquiry form. 

The ME range of Static Frequency Converters convert the source power with a specific input voltage and frequency in to a different output voltage and frequency depending on what the client requires, The units are designed with Power Factor correction to guarantee a perfect sinusoidal input current from 25% to 150% load and low THDi (<1.5%).
