FROG D Single Phase for Cummins iS, Navistar and DDEC
The FROG-D provides a compact way to comply with NFPA requirements for instrumentation on a line voltage power source.(NFPA 1901, 2003 Edition, 188.8.131.52.)
The FROG-D is a digital device that can be used to monitor 120 or 240 volt single phase generators rated from 6 to 45 kW. The small, waterproof, digital display shows Frequency (in Hertz) accurate to 1 decimal point, Current (in Amps) on two separate lines, and Voltage (in Volts AC). For Cummins iS, Navistar and DDEC applications
The FROG-D is more than just a display, it also functions as a Warning System. It constantly monitors inputs and provides a visual warning alarm when a value goes out of normal range. An output is available to connect an optional audible alarm.
Accumulated generator operating hours are stored in a non-eraseable memory.
The FROG-D is a display only version of the FROG governor and is for use with PTO driven generators that have built in governing capabilities. If the generator does not have a built in governor, FRC offers the same displays on the standard FROG Generator Governor. Refer to the FROG Governor page for more information.
The FROG D 3-Phase is available for 120 or 240 volt three phase systems with both delta and star windings. Refer to the FROG D 3-Phase Delta or Star page for more information.
