System and method for load control

摘要

A device includes a load sensor configured to measure a load demand that indicates that a load is operating in an active state or an inactive state. A load switch is configure to selectively supply electric energy to the a load in accordance with a load control signal. A controller in communication with the load switch and the load sensor is configured to compare the load demand to a load threshold, generate the load control signal based at least in part on the load demand relative to the load threshold, and transmit the load control signal to the load switch when the load demand is substantially equal to or greater than the load threshold. The controller is further configured to determine the load threshold based at least in part on the load demand when the load is operating in either the active state or the inactive state.

1. A power-saving device comprising:
a load sensor configured to measure a load demand; a switch to selectively provide electric energy to a load; and a controller in communication with the load sensor and the switch configured to:
compare the load demand to a predetermined load threshold, andtransmit a load control signal to the switch to supply electric energy to the load if the load demand is substantially equal to or greater than the load threshold,wherein the controller is configured to automatically determine the load threshold during a learning mode by transmitting the load control signal to the switch to supply electric energy for a predetermined time interval to the load, the load sensor measuring the load demand during the predetermined time interval to determine an active state and an inactive state of the load.
