PRO BAS Switch-Mode Power Supply 480W 48V 10A
Ask an expert!
The Weidmüller PRO BAS 480W 48V 10A is a high-efficiency DIN rail switch-mode power supply designed for industrial control panel applications requiring a stable 48 V DC bus. With a true wide-range input (85–264 V AC or 110–370 V DC), a 95% efficiency rating at full load, and comprehensive built-in protection functions, it is suited to OEM machinery, process control systems, and industrial communication infrastructure requiring 48 V supply. Up to three units can be connected in parallel for redundancy or increased output capacity.
