This Simple Circuit Turns 220V Into 12V Without a Transformer! 😱

In this video, we’ll build a transformerless power supply circuit that converts 110V/220V AC mains directly into a stable 12V DC output — without using a bulky transformer and SMPS. You’ll learn the working principle, components required, and safety precautions for handling AC mains. ⚠️ DANGER: HIGH VOLTAGE ⚡ Stay Alert — Electric Shock Can Kill! Do not touch exposed wires or terminals. Always switch off power before servicing. Use insulated tools and wear protective gear. Only trained personnel should handle high-voltage equipment. #leddriver #12vpowersupply #actodc #12vdc #electronicsprojects #220v #powersupply #transformerless #ledbulbrepair #repair #circuit
