4.2V power supply for LED display equipment
The XingXiu DNP400L-4.2 supplies 4.2V DC at a rated output power of 336W. It uses a double-transistor forward design with input-to-output isolation and accepts 180–264V AC input.
This model is suited to installations with a nominal 200–240V AC supply. Its input range is an important selection point when replacing a cabinet power supply: it does not include 110V AC. Check the output requirements and mounting arrangement against your existing equipment.
