The introduction of EON Technology�0�3 further extends the technical leadership of
PowerSafe�0�3 SBS batteries: not only do the PowerSafe SBS B14 - 190F monoblocs and
SBS 410 cell retain the bene�0�3ts typically associated with EnerSys�0�3 Thin Plate Pure
Lead technology (long life, high energy density, superior shelf life, etc.), they now
also deliver exceptional cyclic performance in both �0�4oat and fast charge applications,
even in the hottest and harshest operating environments.
Where conventional VRLA AGM batteries struggle to cope with harsh conditions,
remote locations and frequent power outages, the combination of EON and TPPL
technologies makes PowerSafe SBS 2V and 12V batteries the perfect solution for the
challenging operating conditions of today’s telecommunication networks.
With the introduction of the SBS 410 cell, the PowerSafe SBS EON Technology battery
range is now available in two con�0�3gurations: the front terminal design that allows for
maximum back-up power within a given cabinet installation, and the top terminal
design typically used for open rack installations.
For power, performance and reliability, there is no substitute to PowerSafe SBS
EON Technology batteries.
Capacity Range: 62 - 410Ah
高频机逆变器所用IGBT额定电压要比工频机高一倍,但两者的IGBT与二极管的门槛电压、等效通态电阻相差不大;此外由于工频机直流母线Ud较低,需要用输出变压器将逆变器输出电压升压至380V,而高频机的逆变器直连输出,因此工频机逆变器输出电流要比高频机大。
由式(7)和式(9)可见,工频机逆变器的通态损耗比高频机要高,据测算要增加90%~150%。
由于工频机整流器采用不控器件二极管或半控器件晶闸管进行整流,直流母线电压范围较宽,逆变器难以一直工作在优点;而高频机采用全控器件IGBT整流,直流母线电压基本保持不变,逆变器工作在其设计的优点,从而提高了逆变器的效率。
UPS是数据中心的重要基础设施之一,其能耗的降低对数据中心整个生命期内总拥有成本TCO有重要作用。
通过前面的分析可知,高频机造成的能耗要比工频机小,主要的因素是变压器损耗,由于变压器有较大的空载损耗,造成工频机的空载损耗较大,即在较低的负载率时效率不高,能耗较大。
