Power Systems offers aircraft frequency converters

This range of frequency converters is designed for aircraft ground power applications, for outdoors point-of-use installations at aircraft parking stands, in maintenance hangars or in avionics workshops, in aircraft manufacture and for training simulators.

The product utilises power conversion switching technology to provide all types of aircraft with 400Hz power security at exactly the place where it is needed as a more cost-effective and flexible alternative to the restrictive centralised 400Hz systems found at many older airports.

The EF 40 frequency converters are supplied with 115V single-phase output up to 15kVA and from 10kVA to 10kVA with 200V three-phase output.

The basic mechanical construction is in vertical format with ingress protection IP31 or IP41.

For outdoors use in IP54 enclosures, there is a horizontal version available for mounting on a mobile trolley, trailer or floor stands.

The EF series of frequency converters has a high power factor of 0.98 with a low harmonics input stage.

The standard output of the frequency converter is via a circuit breaker for indoor use with optional contactors for outdoor use and can be delivered with a single output or dual output and supplied with flexible cables fitted with standard or custom-designed aircraft connectors.

Optional features include: supplementary metering; 50Hz or 60Hz input frequency; an output contactor with an interlocking 15m flexible cable with aircraft connector; no-break power transfer to aircraft service; remote monitoring by interface PCB RS485; remote monitoring by computer; a second output contactor and interface; ingress protection to IP54; line drop compensation; trolley converters 45kVA and 90kVA; and special paint colours and finishes.
