Appendix A Active Rectifier Unit (ARU)

All ITW GSE 4400 units can be equipped with a 28 VDC

ctive

ectifier

nit (ARU) output.

Both 400 Hz & 28 VDC outputs can be used simultaneously. The total continuous amount of power from the

unit is calculated as the sum of 400 Hz and 28 VDC output and cannot exceed the total 400 Hz power rating

of the unit.
