摘要: Assemblies, systems, and methods which prolong relay life by dynamically compensating the make break contact timing between points of a zero crossing point power supply's waveform are provided according to present disclosure. The cycle components dramatically increased through use these assemblies, due decrease in arcing other physically damaging phenomena contacts relay. disclosure also provides for whereby processor analyzes inductive kickback effect load voltage signal adjust open time such that is minimized. In exemplary embodiments, systems/methods herein advantageously switching corresponds with current cross do so without requiring complicated monitoring components.
