How to know maximum power needed

Hi every:
I will buy a new EML 103e Base Library with 2 HP EML LTO-4 Ultrium 1840 FC Drive and 12 HP LTO4 Ultrium 1.6TB RW Data Cartridge. I need also buy some backup solutions, thinking in APC, but first need to know how I can calculate the power needed for this configuration plus maybe 25% more planning some upgrades at future. I found in tech specs that for this EML series the typical power for 4 drive is 250W but I need to add 20W per 1840 drive? I'm not so sure if this is the correct value for estimate the backups. Can any help me?

Same answer as your other thread.

http://h30099.www3.hp.com/configurator/calc/Power%20Calculator%20Catalog.xls

It contains also links to MSL, EML and ESL libraries.

The BTU/hr and Watts are just two power units, you directly convert from one to the other.

Y recommend using www.wolframalpha.com, just type 1638 BTU/h for example and it will tell you that it's equivalent to 480.1 W or 0.6438 hp.

People in different industries uses mainly one of those units.
