Emergency Transfer Load manager

Emergency Transfer Load manager

Caterpillar offers standard paralleling solutions, which are ideal for use in Distributed system configurations found in Data Center applications as well as Soft Load Automatic Transfer Switch (ATS) applications. The Emergency Transfer Load Manager (EXL) combines standard paralleling controls with an informative Graphical interface and a data access point for s user’s Building Management System. The EXL controls can also be integrated into a switchgear lineup to provide a complete factory-tested solution.
