Allen-Bradley 1794-PS3 Rev A01 Flex I 24 Vdc Power Supply

The Allen-Bradley 1794-PS3 Rev A01 Flex I 24 Vdc Power Supply is a FLEX I/O power module that provides a stable 24 V DC bus to FLEX I/O racks and their connected modules, delivering up to 3 A to support typical I/O loads. It accepts a wide AC input range of 85–265 VAC (nominal 120/230 VAC) and draws up to 86 W real power (205 VA apparent), with a transformer load rating of up to 250 VA, making it suitable for standard FLEX I/O installations in industrial automation environments. Designed to mount in the first slot of a FLEX I/O rack, the PS3 sits adjacent to the 1794-AENT Ethernet adapter and powers the entire FLEX I/O backplane, ensuring consistent supply to all installed modules. The unit’s 24 V output is specified as 20.4–27.6 V DC under load, and its compact footprint measures approximately 87 mm high, 94 mm wide, and 69 mm deep (3.4 x 3.7 x 2.7 in), enabling installation in space-constrained panels.
