GUINAULT SC20

GUINAULT SC20 is a 28 V DC static ground power unit, designed to provide reliable DC power for aircraft electrical systems during maintenance, ground handling, and pre-flight operations. Unlike diesel-powered GPUs, the SC20 is connected directly to the mains power supply, ensuring quiet operation without the need for an internal combustion engine while helping to reduce operating and maintenance costs.

The SC20 is designed for use in hangars, maintenance facilities, and other locations with access to a permanent electrical supply. Thanks to its high efficiency, compact design, and minimal maintenance requirements, it provides a reliable solution for everyday aircraft ground support operations.

Depending on operational requirements, the unit can be supplied as either a mobile version mounted on a trailer or as a fixed stationary installation.
