TritiLED – Multi-year always-on LED

Description TritiLEDs are always-on battery powered LED glow lights for general night-time marking use. Radioactive gaseous tritium light sources (GTLSs) are allowed in the United States in several consumer product categories, including watches, compasses, and gun sights, but general-purpose markers are considered "frivolous" and are prohibited. Leveraging advances in LED efficiency, battery capacity, and m ...

Limiting Inrush Current

Inrush current or input surge current refers to the maximum, instantaneous input current drawn by an electrical device during its initial turn on. Power converters also feature high inrush currents relative to their steady state currents that may be several times their normal full-load current when first energized. The inrush current of a power converter is typically the charging current of the input capaci ...
