FROG Generator Governors

The FROG generator governor monitors and regulates PTO driven generators to maintain a steady frequency of 60 Hz.

The FROG provides a compact way to comply with NFPA requirements for instrumentation on a line voltage power source rated at 8 kW or larger. (NFPA 1901, 2003 Edition,

The FROG is a generator governor and a 'generator output display panel' in the same module. It regulates the frequency of the generator by adjusting the engine speed. This controller will automatically maintain a steady speed regardless of the engine or generator load.
