Hi all,just wanted to show you my new 0-400V high-power variac, made a video of it. It's a motor driven 3-phase variac with a power rating of 30kVA. It has a nameplate rating of 45A per phase and can make twice the power for 2 minutes (90Amps per phase, 60kVA). 2x2 Contactors per phase and so it even has balancing chokes between each pair of contactors on each phase. The contact-surface below them is silver coated, so it has a dark colour.
