POWER MONITORING AND MANAGEMENT WITH REMOTE ACCESS
First Claim
1. An apparatus comprising:
- at least one power monitor comprising;
a set of input terminals at which to receive input power and a set of output terminals at which to provide output power;
a switch circuit electrically interposed between the input and output terminals and compelled into a conductive state and a non-conductive state in accordance with a signal provided thereto; and
a control circuit to transition between a plurality of states responsive to levels of deviation from a nominal level in a process variable and to provide the signal to the switch circuit in accordance with signal levels thereof assigned to the respective states;
an access device communicatively coupled to the power monitor to provide action criteria data thereto that define state transition boundaries at levels of the process variables corresponding to the amounts of deviation; and
a communication module in the power monitor and a communication module in the access device between which a communication channel is formed over which the action criteria data are transmitted.

Abstract
A supply voltage monitor includes a switch circuit that enables coupling of an AC power supply to a load. A control circuit switches the switch circuit from a non-conductive state to a conductive state, and vice-versa, based upon a state of a state machine implemented by the control circuit, and further reports anomalies in process variables, such as voltage and current levels, temperature, etc., based on the state of the state machine. The transition criteria that is met to compel a transition in state is selectable by a user by way of a user interface. The transition criteria may correspond to different power levels that define a range over which the power is considered nominal and a range over which the power is considered to be an anomaly. The transition criteria additionally define what type of anomalies are reported without a change in the conductivity of the switch circuit.
