1756-PA75: Standard DC Power Supply
The 1756-PA75 is the Standard DC Power Supply covered on this page. The attribute that decides whether it fits the existing installation without modification is 32-140 Fahrenheit (0-60 Celsius).
The reason to specify this exact variant is standard dc power supply. A power supply or battery in a controller rack is sized against the backplane budget, not in isolation. standard dc power supply 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 32-140 Fahrenheit (0-60 Celsius) against the rack's requirement prevents a supply that fits the slot but cannot hold the load.
