The FROG-D Three Phase Delta Generator Display provides comprehensive monitoring and protection for three-phase Delta winding generators used on fire apparatus, rescue vehicles, and other mobile power systems. Designed for generators rated from 10 to 135 kW, the FROG-D continuously monitors generator frequency, voltage, and current while providing operators with critical performance information needed to maintain safe and reliable power generation.
The system utilizes a dedicated signal interface module mounted near the current sensors and voltage transformers to reduce cable lengths and simplify installation. Generator voltage and current information are transmitted to the display module through a two-wire datalink, providing accurate real-time monitoring in a compact, easy-to-read display. Built-in warning functions alert operators to overload conditions, voltage fluctuations, and elevated hydraulic oil temperatures, helping protect both the generator and connected equipment from damage.
