Retrofit of an existing bench: 320 kW power channel relocated

A VES2 320 kW power channel is relocated to a climatic chamber shared with another channel, to extend the site's test capabilities.

New safety analysis, adapted electrical schematics and modified cabinet wiring to ensure both channels stop simultaneously in case of failure.
Independent control of each power channel, developed on top of a legacy PAtools 6.1 database.
Climatic chamber control logic reprogrammed so both channels can use it.
