Abstract
An apparatus and method for minimizing inrush power. The method includes transmitting a load energization signal from a primary microcontroller to a logic latch or secondary microcontroller, transmitting a zero-cross voltage signal from a zero-cross sensor coupled to the load power to the logic latch or secondary microcontroller, and transmitting an energize signal from the logic latch or secondary microcontroller to a relay after the receipt of an energize signal from the primary microcontroller and after receipt of a zero-cross signal.
