Abstract
A cold load pickup device includes a load controller comprising a microprocessor or microcontroller. The device is programmed to detect restoration of power after a power outage on a circuit powering an electric load. A power outage time for the power outage is determined, and a startup delay for the electric load is determined based on the power outage time. A startup delay mechanism, such as a power relay operated by the load controller or switching of the load on/off by the load controller, is configured to apply the startup delay after the detected restoration of power before restarting the electric load. In some embodiments, the startup delay for the electric load is determined based on the power outage time and a startup delay versus power outage time curve stored in a non-volatile memory of the load controller.
