The FROG-D Three Phase Star Generator Display provides real-time monitoring and protection for three-phase generator systems used on fire apparatus, rescue vehicles, and other mobile power applications. Designed for generators rated from 10 to 135 kW, the FROG-D continuously displays frequency, voltage, and current information while helping operators monitor generator performance and identify potential electrical issues before they become critical.

The system utilizes a dedicated signal interface module mounted near the current sensors and voltage transformers to minimize cable runs and improve installation efficiency. Current and voltage data are transmitted to the display module through a two-wire datalink, providing accurate generator performance information in a compact, easy-to-read format. Built-in monitoring functions alert operators to current overloads, voltage fluctuations, and high hydraulic oil temperatures, helping protect both the generator and connected equipment.
