Notes:

Primary power supplies in the Lightning were generated by an AC Alternator and a DC Generator both driven by an air turbine drive unit. The aircraft has 28VDC and AC supplies at both 115 V, three-phase, 400 c/s power supply voltage for equipment and 4VAC for lighting The function of this unit seems to be power conditioning to provide the specific supplies required by the Air Data Computers. Similar units were fitted to the Buccaneer. The relationship between ‘Type’ and ‘Mk’ numbers is not known but it would seem that each ‘Type’ can have incremental ‘Mk’ numbers.

This is a Power Supply Unit 'Type B'.
