Engine Paralleling and Integration Control (EPIC)


Caterpillar offers standard paralleling solutions, which can be provided in a wide variety of market applications. The Engine Paralleling and Integration Control (EPIC) product line provides standard paralleling controls in a remote cabinet separate from the engine generator set and separate from switchgear (breakers and bus). EPIC allows for operating generator sets in pre-configured Emergency Standby, Prime power and Parallel with Utility configurations. It eliminates the need for traditional hardwired components such as synchronizers, power factor controllers, load share modules, cross-current compensation devices, annunciators, switches and meters by replacing them with the industry proven Caterpillar paralleling logic control architecture and color touch screen interface, and is an alternative to switchgear mounted controls.
