1756-PB75: ControlLogix Power Supply, 18 32VDC
The 1756-PB75 is the ControlLogix Power Supply, 18 32VDC covered on this page. The attribute that decides whether it fits the existing installation without modification is 14.0 x 11.2 x 14.5 cm.
On this unit controllogix power supply, 18 32vdc is the figure that decides fit and function. A power supply or battery in a controller rack is sized against the backplane budget, not in isolation. controllogix power supply, 18 32vdc is whether the unit delivers the voltage and current the rack draws at full load, and whether the battery holds programme and configuration through a power loss. Checking 14.0 x 11.2 x 14.5 cm against the rack's requirement prevents a supply that fits the slot but cannot hold the load.
