Converter-Rectifier Units are used for replacing old versions of Transformer-rectifier units (TRU).
They are to be used with 400Hz Ground Power Units.
The ElectroAir EAR-800C Converter –Rectifier Unit is an optional component for installation on 400Hz diesel engine driven Ground Power Units, to provide power for aircraft that require 28,5VDC. The EAR-800C can be also factory installed on any new diesel engine driven GPU. Moreover, it can be retrofitted to many older diesel and synchronous motor driven Ground Power Units.
Please consult us what type of hardware is needed to install EAR-800C on “in service” units.
This unit can also perform as usual rectifier with standard 400Hz, 3- phase 200V input. Execution can be either stationary or towable mobile. In the case of needing to supply 28,5VDC to some aircrafts, the EAR-800C can be easily connected to a frequency converter with a regular 400Hz plug.
Unlike any of the others transformer-rectifier units, EAR-800C converter-rectifier units have a converting part with a bank of capacitors, which allows the unit to withstand high dynamic overloads in spite of diesel engine characteristics.
