Overview

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 a user’s Building Management System. The EXL controls can also be integrated into a switchgear lineup to provide a complete factory-tested solution. The EXL allows for operating generator sets in pre-configured Emergency Standby, Prime power and Parallel with Utility configurations for single generator/single Utility applications.
