Abstract: A power control system using fiber optics and photoelectric devices for remotely and safely controlling power to a load. The system includes a power control device, a light controller and fiber optics. The power control device includes a light generator, a light sensitive device and an electronic switch. The electronic switch controls the power to the load in response to the electrical output of the light sensitive device. The light from the light generator is transmitted to the input of the light controller by a fiber optics line. The light from the output of the light controller is connected to the input of the light sensitive device by another fiber optics line. The light sensitive device converts the light signal at its input to an electrical output signal that controls the electronic switch that controls power to the load. The light controller can transmit all of the light, block all of the light, or variably modulate the light and thereby remotely and safely control the load in any desired manner.
