1756-PSCA2XT: Redundant Power Supply Chassis Adaptor
The 1756-PSCA2XT is the Redundant Power Supply Chassis Adaptor covered on this page. The attribute that decides whether it fits the existing installation without modification is -25 to 70°C.
This configuration's redundant power supply chassis adaptor is the attribute that drives the replacement decision. A power supply or battery in a controller rack is sized against the backplane budget, not in isolation. redundant power supply chassis adaptor 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 -25 to 70°C against the rack's requirement prevents a supply that fits the slot but cannot hold the load.
