1.0 INTRODUCTION
Many systems and devices in the aerospace industry,
and other fields, require a DC voltage of 28 volts. As
this cannot be supplied by the utility directly, converters
are employed which supply the necessary voltage and
eliminate supply irregularities to a limited extent.
Normally these units are used to supply smaller aircraft
with electric power. There are special reasons why
aircraft need a 28V DC voltage for internal supply. To
save costs in maintenance and operation, and also for
environmental reasons, aircraft are supplied by
external electrical power supplies when they are
parked at airport terminal stands with their engines
shut down.
This manual describes the Tronair 28V Ground Power Unit (GPU). If you follow these instructions you will be able to handle
the equipment with confidence and utilize all its facilities.
NOTE 1. Naturally an operating manual cannot cover every conceivable installation, operating, maintenance or servicing
situation. Should problems arise, or if the data in this manual is not sufficiently detailed, please contact your local
Tronair representative who will be pleased to give further assistance.
2. If the equipment is installed for use as an aircraft ground power system, please pay particular attention to Section
10, which summarizes the special features of this type of application.
