The Astron LS-3A is a robust, solid-state, electronically regulated linear power supply designed for reliable DC power delivery. Its primary function is to provide a stable 13.8V DC output, suitable for a variety of electronic applications, including communication equipment, laboratory instruments, and hobbyist projects. The unit incorporates essential protection features such as fold-back current limiting to safeguard against excessive current and shorted outputs, as well as crowbar over-voltage protection on all models, ensuring the connected equipment is shielded from voltage spikes. The Astron LS-3A is engineered to maintain consistent regulation and low ripple even under conditions of low line input voltage, contributing to the stability and longevity of powered devices. Manufactured in the USA, it is constructed with heavy-duty, high-quality materials to ensure durability and consistent performance.
