STATIC FREQUENCY CONVERTER :
Present day aircrafts dominantly use electrical power. It is normally 115V, 3 Phase, 400Hz which is converted from 415V, 3 Phase, 50 Hz supply.
It is suitable for motor load and is transformed and rectified to various levels for use in avionics loads. Its nature and quality is specified by Mil-std 704. Statcon Electronics product is based on technology from Statcon Power Controls Ltd are fully compliant with these requirements.
