FM2807 Low Power Ground Fault Interrupter
The FM2807 is a low power controller for AC outlet ground fault interrupters. Contained internally
are a zener shunt regulator, an op amp, and an SCR driver. With the addition of two sense
transforms, a bridge rectifier, an SCR, and a few additional components, the FM2807 will detect
and protect against both hot wire to ground and neutral wire to ground faults.
