Nur für den internen Gebrauch Identifying System Power Requirements
Checking Whether the Output of a Power Supply Unit is Sufficient
● HiPath 3500 with UPSC-DR
The maximum nominal output of the –48-V output can be increased from 53 W to 110 W
by using the external power supply Powerbox PB3000 with LUNA2.
● HiPath 3300 with UPSC-DR
The maximum nominal output of the –48-V output can be increased from 53 W to 110 W
by using the external power supply Powerbox PB3000 with LUNA2.
Sample calculation for a HiPath 3550
1. Determine secondary power requirement at the 5-V output
The maximum nominal output of UPSC-D at the 5-V output amounts to 40 W and is enough
to cover the specified power requirement.
power requirements of the boards/
components used =
7.00 W 1 x CBCC
10.00 W 1 x HXGS3 (including ventilator
kit)
0.90 W 1 x TS2N
2.40 W 3 x SLU8
1.30 W 1 x 8SLA
5.00 W 1 x SLC16N
0.00 W 12 x BS3/1
= secondary power requirement at the
5-V output =
26.60 W
