This 100% brand new, original power supply module converts wide-range AC input into stable, filtered DC voltages required by CPU processors, communication interfaces, and I\/O modules. Engineered for the rigors of 24\/7 industrial operations, the PW482-10 maintains logic integrity by suppressing line noise and protecting sensitive downstream electronics from power surges. Its high-efficiency design ensures consistent power delivery to mission-critical Field Control Units (FCU), making it a cornerstone of plant-wide automation
