EGCP‐2

Applications

The EGCP-2 is a complete microprocessor-based engine- generator control and management package. It is designed for use with an automatic voltage regulator and a speed control to automate and protect diesel or gas engine based generator sets.

Designed for up to 30 000 kW generator sets, the EGCP-2 can be configured to operate stand- alone or utility paralleled.

A network of EGCP-2 controls is capable of controlling up to eight un-manned generator sets for base-load, peak shaving or backup power generation.
