Checking Whether the Output of a Power Supply Unit is Sufficient
2. Determine secondary power requirement at the –48-V output
The maximum nominal output of UPSC-D at the –48-V output amounts to 53 W and is
enough to cover the specified power requirement.
power requirements of the boards/
components used =
0.50 W 1 x CBCC
2.80 W 1 x HXGS3 (including ventilator
kit)
0.00 W 1 x TS2
0.00 W 3 x SLU8
1.30 W 1 x 8SLA
0.00 W 1 x SLC16N
24.00 W 12 x BS3/1
+ power requirement of connected work-
point clients, key modules and adapt-
ers =
0.56 W 1 x optiset E memory
4.32 W 6 x optiPoint 500 advance
0.85 W 1 x optiset E advance confer-
ence/conference
8.40 W 12 x optiPoint 500 basic
2.40 W 8 x optiPoint 500 entry
0.00 W 2 x Hicom Attendant BLF
0.00 W 2 x optiPoint BLF
0.40 W 8 x optiPoint key module
0.50 W 2 x optiPoint acoustic adapter
1.80 W 6 x analog telephones
= secondary power requirement at the –
48-V output =
