12V, 5A DC Power Supply (SMPS)
A Switched‑Mode Power Supply (SMPS) is an efficient power converter that steps down AC mains voltage (usually 100–240 V AC) to a stable DC output using high-frequency switching. Unlike traditional linear power supplies, SMPS units are compact, lightweight, and highly energy-efficient.
