Abstract
A wall box mounted remotely operated voltage module utilizing a low voltage DC control signal which is remotely generated. A power semi conductor device is triggered to deliver a predetermined amount of power from the source of AC electrical power to a load. The AC electrical power is rectified and transformed to produce a low voltage rectified DC signal. A comparator generates a triggering signal to the power semi conductor utilizing the low voltage rectified DC signal and remotely generated low voltage DC control signal as imputs. The comparator also serves as a compensator for changes in the voltage of the AC electrical power from the source.
