5 Appendix B. Power Consumption Calculation
This chapter shows the description about the calculation of the power consumption, the battery capacity and
the rectifier DC output power needed in a system. The examples of calculation are described in detail in the
cases of each kind of system configuration.
The following table shows the power consumption of each item of the iPECS UCM system.
This material is not precise. These are the approximate data estimated assuming the maximum consumption
so that power consumption can be estimated easily.
Therefore, the actual measured data during system operation may be different.
Power Consumption
ITEM Power (Max.) Note
UCM-S2K 25W Mounted in UCM-MGC3 or UCM-1URMC.
UCM-ASLM
50W In the case that SLT line busy rate is 20 %
80W
In the case that SLT line busy rate is 100 %.
UCM-MATM
15W Use this value in the case of CO 16 ports.
40W Use this value in the case of EM/LD 16 port.
UCM-MDTM2/X2 7W -
UCM-VPCM
7W
-
UCM-MGC3 20W Consumed by LANU and FAN Unit.
UCM-PSUD
(duplicated)
10W
Calculating maximum output capacity,
add this value to total power consumption in a UCM-MGC3.
In the case where DC -48V power is supplied from rectifier, UCM-PSUD is mounted in UCM-MGC3. UCM-
PSUD consumes 10 W as the maximum power for playing the role of DC/DC converter to produce DC + 5 V
power from DC -48V power.
First of all, sort out items mounted in UCM-MGC3. Secondly, calculate the maximum power consumed by
items mounted in UCM-MGC3. Thirdly, add to the result the total power consumed by UCM-S2K and items
mounted in UCM-1URMC.
The AC power consumption calculated as above is able to be used to check on the electrical equipment or to
calculate UPS capacity needed for the system.
