Overview
The Lambda SWS300-24 is a compact switching-mode power supply engineered for reliable 24VDC power delivery in industrial automation, control systems, and factory environments. Manufactured by TDK-Lambda (formerly Nemic-Lambda), this 300W unit accepts universal 100–240VAC input and provides 13A continuous output at 24VDC. Its active power factor correction (PFC) design minimizes inrush current and meets IEC61000-4 input transient protection standards.
