幫忙聽英文影片字幕

有沒有聽力不錯的人可以幫我聽聽下列這段影片的英文??(從第42秒到結束)
然後麻煩幫我將英文打下來，如果可以的話覆上翻譯更好。
十分感謝^ ^

這是我自己聽到的部分
可能有不少地方聽錯
但希望多少有幫到一些忙

0:42 Fundamentally IT equipment is DC powered.Currently it's fed from
0:48 AC power is transformed four or five times and at the final step
0:53 is transformed into DC around the IT equipment
0:57 These transformations
0:58 can result in efficiency losses for up to 20 percent.
1:02 Additionally,
1:04 transformers generate heat
1:06 and that heat has to be
1:07 accounted for by the HVAC system
1:09 but we remove the transformation
1:11 we remove the additional HVAC equipment required
1:14 this can result in savings of up to thirty percent
1:18 Finally because there is less equipment
1:20 less core spaces is taken up so your side vere equipment
1:23 can actually be reduced by up to thirty percent by using a
1:27 DC based system.
1:31 So why haven't we used DC in data centers until now?
1:35 For one of the primary reasons
1:37 is the circuit protective devices
1:40 have been based on electrical mechanical chips.
1:44 Now, for the first time
1:46 we have a fully functional microprocessor based chip
1:50 so that you can tell your circuit protection
1:52 in an industry and where the requirements are
1:56 for highly available
1:58 resilient power.
2:04 with cost about ten minutes in data center approaching a million dollars
2:07 a hour
2:08 we need the reliability and
2:09 repeatability of
2:10 a microprocessor based chip unit
2:12 that up until now hasn't been available for HVAC servers
2:20 technological advances in circuit protection
2:23 are making DC data centers a reality
2:26 this allows significant reduction in both
2:29 capital and operating expenses
2:32 consider DC for your next data center!
