GCP-20 (AMG 3/NEB)

Genset control for Single/Parallel Operation

The GCP-20 Series genset control is designed to provide total control for stand-alone and multiple unit applications in isolated or mains parallel operation. Load management features include automatic base/peak shaving, import/export control and emergency power/back up power generation.

There are two GCP-20 Series Packages available for various genset applications. The GCP-20 is designed for stand-by gensets. Open or closed transition power transfers including logic for two circuit breakers. The GCP-21 is designed for continuous parallel operation and has control logic for one circuit breaker. The GCP-22 has control logic for two circuit breakers that enable automatic power transfers like open transition, closed transition and softloading.
