Identifying the Primary System Power Requirement

Procedure
Proceed as follows to identify the primary power requirement of a system:
1. Determine overall secondary power requirement
power requirements of the boards/components used
+ power requirement of connected workpoint clients (analog and digital telephones),
key modules and adapters
= overall secondary power requirement
2. Identifying primary power requirement
overall secondary power requirement
+ requirements of power supply units (LUNA2 = 9 W, PSUP/UPSC-D/UPSC-DR = 12
W respectively)
+ requirements of Powerbox PB3000 with LUNA2 (9 W)
= the result should be multiplied by the factor 1.3 to allow for the degree of efficiency of
the power supply.
