+86 18150117685Standard nonredundant AC chassis power supply for ControlLogix 1756
This standard ControlLogix chassis supply accepts 85 to 265 VAC and mounts on the left side of a compatible 1756 chassis to energize the backplane.
Its four backplane rails share a 75 W combined limit, so engineers must verify both the total power calculation and the published current ceiling for each rail before installation.
Ordering note: Verify the complete model, installed system, revision and current manufacturer documentation before purchase or installation.
