  • Patent number: 9853494
    Abstract: A system for providing backup power to a facility includes a generator and a controller. The controller is configured to operate the generator until a condition is met, determine a load history that occurs while operating the generator until the condition is met, determine a cool-down time based on the determined load history, and run the generator to the point when the condition is met and in an unloaded condition for the cool-down time.

  • Patent number: 9577423
    Abstract: A power system is for a facility. The power system includes a load panel powered from a split phase electrical distribution configuration having a first line, a second line and a neutral. A two-pole circuit interrupter in the load panel receives power from the first line, the second line and the neutral, and protects an unbalanced load. The two-pole circuit interrupter is structured to trip open or open responsive to an input. A circuit in the load panel is structured to determine that the neutral is broken or missing and responsively output to the input to cause the two-pole circuit interrupter to trip open or open.

  • Patent number: 8766489
    Abstract: An automatic transfer switch includes first and second inputs inputting first and second voltages; a first output outputting a start signal; a first timer timing a first time after the second voltage is available; a second timer delaying for up to a second time before outputting a transfer signal, the second time being reduced by the first time when the second voltage is available; a transfer mechanism selectively electrically connecting one of the inputs to a second output; and a circuit cooperating with the inputs and the transfer mechanism, causing the start signal to be output responsive to the voltages not being available, and causing the transfer mechanism to electrically connect the second input to the second output in response to the transfer signal.

  • Patent number: 7948117
    Abstract: A transfer switch controller is for a transfer switch, which cooperates with a plurality of loads including an air conditioner. The transfer switch controller includes a first input structured to input a thermostat start request signal for the air conditioner, a second input structured to determine power consumed by the loads, an output structured to output a start signal to the air conditioner, and a circuit. The circuit cooperates with the first input, the second input and the output. The circuit causes the start signal to be output by the output responsive to the thermostat start request signal of the first input if the determined power consumed by the loads is less than the difference between a predetermined maximum power output of a generator and a previous maximum peak start up power consumed by the air conditioner.

  • Publication number: 20100141047
    Abstract: The disclosed concept provides for a closed transition automatic transfer switch assembly having only two switch assemblies. This system utilizes a first switch assembly and a bypass switch assembly. The switch assemblies are each physically coupled to two power sources as well as the system load. The switch assemblies each include a power actuated contact arm. Each contact arm is coupled to, and in electrical communication with, the system load. Each contact arm may further be placed in one of the following configuration; a first configuration wherein the contact arm couples, and provides electrical communication between, the first source and the system load conductor, a second configuration wherein the contact arm couples, and provides electrical communication between, the second source and the system load conductor, and a neutral configuration wherein neither the first source nor the second source is coupled to, and in electrical communication with, the system load conductor.

  • Patent number: 7615888
    Abstract: A loadcenter for supplying power to a critical load is capable of isolating a distribution panel distributing power to the critical load from another distribution panel distributing power to a non-critical load to enable the isolated distribution panels being supplied with power from separate generator power sources in response to power supplied by a utility power source to both distribution panels becoming unacceptable.

  • Publication number: 20090179498
    Abstract: A transfer switch controller is for a transfer switch. The transfer switch controller includes a first input having an alternating current voltage and structured to input power from a utility power source, second inputs structured to input remote or local signals, and an output structured to output an alternating current voltage to a standby generator. A normally closed switch, such as a relay, includes a number of normally closed contacts electrically connected between the first input and the output. The normally closed contacts are normally closed to cause the alternating current voltage of the first input to be normally output to the alternating current voltage of the output. A microprocessor cooperates with the second inputs and the normally closed switch. The microprocessor causes the normally closed switch to open responsive to one or more of the remote or local signals.

  • Patent number: 7531919
    Abstract: A loadcenter supplies power to a non-critical load, a critical load and an ultra-critical load, and is capable of isolating a first distribution panel distributing power to the non-critical load from a second distribution panel distributing power to the critical load to enable the isolated distribution panels to be supplied with power from separate generator power sources in response to power supplied by a utility power source to both distribution panels becoming unacceptable. A third distribution panel distributes power to the ultra-critical load and is selectively supplied with alternating current (AC) power from either the second distribution panel, when the second distribution panel has AC power, or from AC power generated from direct current (DC) power stored in a battery when the second distribution panel lacks AC power.
