<p>The computer controlled AC electrical termination of the present invention comprises a microcontroller unit (MCU) (14), a bistable relay (128), a power supply operated in a pulsed mode and at least one sensor. In one embodiment, the MCU (14) senses an electrical condition via the electrical sensor, and control the bistable relay (128) via the power supply operated in a pulsed mode. Voltage and current sensors (12) are input to the microcontroller (14), from which over-voltage, under-voltage, miswired neutral, lack of ground connection, ground fault currents and the like are detected by use of an algorithm stored in the microcontroller (14). Mechanical sensors (416, 418) are provided to sense the presence of inserted prongs (412), which is used by the microcontroller (14) to detect child tampering and shut off output power. The microcontroller (14) in each respective AC electrical termination is responsive to digital signals from the central control computer (654) to remotely control and monitor a variety of power functions.</p> |
