DEIF’s front-mounted and compact controller platform, the Genset Control Unit, GCU 100, has been designed with performance and longevity in view and to secure reliable operation in harsh maritime environments.

Built for basic control, monitoring and protection of marine engines and gensets, the sturdy unit features protection, monitoring and  control functionality with agraphic display for easy and accurate presentation of values and alarms. Moreover, it also features a threephase AC voltage measuring circuit for generator and busbar to enable generator protection and breaker handling.

A variant with automatic black-out detection and genset start, the GCU 113 is available for emergency  gensetcontrol: when power on the main busbar has been restored, the unit is able to automatically switch back to supply from main busbar and stop the emergency generator.
