PN: 147-6C (90kVA)

This Converter Has Been Realized In Order To Supply High Quality 115/200Vac 400HZ Output

Main Features

The static frequency converter has been designed in order grant an high quality and stable output at 115/200Vac at 400Hz in the aeronautic application when an wave form of high quality is required.

The typical use of this converter is to supply power to aircraft on ground and many other ground based application at 400Hz. The P/N 147-6B / 147-6C Static frequency converter has been designed for the use both in hangar and also outside on the airfield. The frequency converter is composed by an waterproofed cabinet realized with metallic structure provided by metallic and removable panels allowing the access for maintenance to the internal components.

In order to have and high maneuverability the converter is provide with four caster wheels and upon request could be supplied also mounted on a trailer.
