Appendix B Power Consumption
General
At an ambient temperature of 40°C (104°F) it is considered unnecessary to calculate
the heat dissipation requirements for a standard AC 800M Controller with S800 I/O
configuration, mounted within ABB floor-mounted or wall-mounted cabinets.
For a standard AC 800M Controller configuration housed within a floor-mounted or
wall-mounted cabinet, the recommended fuse rating for the external mains supply
is:
Should the configuration be other than that stated, detailed instructions for
calculating current consumptions can be found in the following text.
The following tables present current consumption and power dissipation for all
relevant hardware units included in AC 800M Controller.
Use this information:
•
dimensioning the supply requirements of an AC 800M and S800 I/O
configuration.
•
calculating cabinet-generated power loss.
The values given in the tables are typical and adapted to these applications. It is
assumed that 70% of unit channels are active simultaneously.
