Power Consumption
Original instructions
Calculation Table
The power required by a rack depends on the type of modules installed.
NOTE: Two redundant power supplies on the same rack are not summable.
Calculate the global power consumption to define the power supply module to be installed on the rack:
Power
Calculation
Result
P 3.3 V rack = power required on the 3V3_BAC output
current absorbed on the 3V3_BAC output by all modules (mA) x 10-3 x 3.3
=................W
P 24 V rack = power required on the 24V_BAC output
current absorbed on the 24V_BAC output by all modules (mA) x 10-3 x 24
=................W
P 24 V sensors = power required on the 24V_SENSORS output
current absorbed on the 24V_SENSORS output by all modules (mA) x 10-3 x 24
=................W
total power required
P 3.3 V rack + P 24 V rack + P 24 V sensors
=................W
NOTE: Control Expert software can display the power consumption budget for a given configuration.
The following tables give the average power consumption per module. The average value is calculated regarding the maximum and typical consumptions.

(1) Current consumption at a temperature above 50 °C (122 °F). At a temperature of 30°C (86 °F) the current consumption is 1,200 mA.
NOTE: To lower the current consumption of the BMENOC0301/11 module, you can disable unused communication ports. This applies only to PV<13 for the BMENOC0301 module and PV<14 for the BMENOC0311 module.
