Weidmueller WSI 4/2/LD 140-250V AC/DC

The WSI 4/2/LD 140-250V AC/DC is likely an industrial power supply or electrical device that operates within a voltage range of 140 to 250 volts, supporting both AC (alternating current) and DC (direct current) inputs. The "WSI" may refer to the specific model or series, and "4/2" could indicate a particular configuration or version within that series. The "LD" may suggest features like low dropout or low-duty cycle for efficient performance. This device is typically used in industrial or commercial applications requiring stable and flexible power conversion and regulation.
