The Schneider Electric ABLU3A24200 is a Modicon Universal regulated switch-mode power supply that converts a 380-500 V AC three-phase input into a stable 24 V DC output at 20 A, delivering 480 W. Built in a metal enclosure for a 35 mm DIN rail, it protects connected loads against overload, short-circuit, and overvoltage with automatic or manual reset.
The ABLU3A24200 suits three-phase 380-500 V AC installations that need 20 A of continuous 24 V DC output - its metal enclosure and Universal input range cover both European and North American three-phase voltages without a separate model. Where the load draws more than 20 A, the 40 A Universal-range unit in the same family is the better fit; where only single-phase or DC supply is available, a compact single-phase Modicon ABL unit applies instead.
