These systems integrate and monitor multiple critical components, including generators, uninterruptible power sources, diesel generators, electrical switchgear, power distribution units, variable frequency drives, automatic and static transfer switches, air-cooled and water-cooled chillers, pumps, cooling towers, heat exchangers, Computer Room Air Handlers (CRAHs), and air economizers. Read and interpret electrical schematics and control panel drawings with a basic understanding of closed-loop controls, field sensor scaling, and functions typically performed by industrial controllers.
