5.1.2—Power Supply Module Specifications
All Temperature ratings specify the System Ambient
Temperature as measured at the front of the MicroNet chassis.
The Power Supply operating temperature range is –10 to +65 °C
with de-rated 5 Vdc output current above 55 °C. See Power
Supply specifications.
For a particular system configuration, use the MicroNet Power
Program to calculate the output current requirements (24 V, 5 V)
as a function of the Chassis, CPUs, and I/O modules used in the
system.
