APPENDIX D: ACE3600 MAXIMUM POWER RATINGS
Power Rating Tables
The tables below list the typical maximum power consumption (at room temperature) for each
of the ACE3600 RTU building blocks (CPU, Power Supply, I/O modules, radios, etc.) and the
maximum peak power allowed for a fully loaded RTU, based on the housing type.
The values in the tables below are derived by using the power supply (AC: 100 to 240 VAC or
DC: 18 to 72 VDC and 13.8 VDC) and have the power supply efficiency factor included in
them.
Before deploying your RTU, add up the power consumption of all components of your system
to verify that it is within the maximum peak power for your housing type. In systems with I/O
expansion, consider all modules which consume power from their respective AC/DC main
power sources when calculating the required power requirements.
