POWER METERING AND LOAD CONTROL DEVICE
First Claim
1. A power measurement device for monitoring power delivered from a source of electrical power to a load, comprising:
- a controller configured to receive a line voltage supply input and a current input, the current input being indicative of a current drawn by the load;
a load control device coupled between the controller and the load and configured to interrupt power supplied to the load through the measurement device; and
a configuration module coupled to the controller and configured to enable rule-based configuration of the measurement device;
the controller comprising a memory in communication with a processor, the memory comprising program instructions for execution by the processor to;
calculate a value of power consumed by the load;
compare the value of the power consumed to at least one predetermined control parameter; and
enable the load control device to interrupt power to the load based on the comparison.

Abstract
A power measurement device for monitoring power delivered from a source of electrical power to a load, includes a controller configured to receive a line voltage supply input and a current input, the current input being indicative of a current drawn by the load, a load control device coupled between the controller and the load and configured to interrupt power supplied to the load through the measurement device, and a configuration module coupled to the controller and configured to enable rule-based configuration of the measurement device. The controller includes a memory in communication with a processor, the memory including program instructions for execution by the processor to calculate a value of power consumed by the load, compare the value of the power consumed to at least one predetermined control parameter, and enable the load control device to interrupt power to the load based on the comparison.

13. A system for measuring power consumption of at least one device coupled to an AC power source, comprising:
-
a controller comprising at least one voltage input for receiving a voltage from the AC power source to which the device is connected and at least one current measurement input for receiving values of current being drawn by the device, the controller further comprising a memory in communication with a processor, the memory comprising program instructions for execution by the processor to calculate a power consumption of the device based on the at least one voltage input and the at least one current measurement input; and a load control device coupled to the controller and configured to interrupt power to the device, the memory comprising program instructions for execution by the processor to; compare the power consumption of the device to at least one pre-determined threshold value; and enable the load control device to interrupt power to the load based on the at least one pre-determined threshold value. - View Dependent Claims (14, 15, 16, 17, 18)
