These series features silver-coated terminals, which improve the electric conductivity. To optimize high rate performance a unique paste formula have been applied to the plate technology.

This series also features AGM separators, which use less electrical resistance to improve the current.

 

This series is specifically designed for 19 or 23 inch power cabinets. The front terminals make the installation and maintenance easy. The unique valve design reduces water loss and prevents air going inside the battery.

Capacity

Amount of charge available from a battery or cell. Measured in ampere-hours. There are various sub definitions of capacity as listed below depending on the conditioned under which it is measured.

Actual Capacity

Cell capacity of a fully formed and fully charged cell when measured under non-standard conditions including non-standard end of discharge voltage.

Available Capacity

Capacity of a fully formed and fully charged cell delivered under non-standard conditions including non-standard end of discharge voltage.

Dischargeable Capacity

Capacity which a partially discharged cell can deliver before it becomes fully discharged or the amount of capacity that can be withdrawn after a limited charge input.

容量

 

从电池或电池中获得的电量。以安培小时为单位。下面列出了各种能力的子定义，这取决于其测量所依据的条件。

 

有效容量，实际生产（能）力

 

在包括非标准放电电压在内的非标准条件下测量完全成形和全充电电池的电池容量。

 

有效功率，可用功率，有效容量

 

在包括非标准放电电压的非标准条件下交付的完全成形和全充电电池的容量。

 

可分辨率卡帕提

 

部分放电电池在完全放电之前可以提供的容量，或者在有限的电荷输入后可以撤回的容量。

 

Nominal Capacity

Capacity typically delivered under standard conditions; a value greater than rated capacity which is a minimum value.

Permanent loss of Capacity

Reduction in cell capacity from the "fully formed, as new" value, measured under standard rating conditions, that is not recoverable by reconditioning.

Rated Capacity

Capacity value shown in the specification sheet. The minimum expected capacity when a new, but fully formed, cell is measured under standard conditions. The basis of the C rate. Note that rated capacities depend on the standard conditions used which may vary from battery to battery.

Residual Capacity

Capacity remaining after discharge.

Retained Capacity

Capacity remaining in a cell after an open circuit rest period. The result of self- discharge.

Standard Capacity

Cell capacity measured under standard conditions.

Temporary Loss of Capacity

Reduction in cell capacity that is recovered when the cell is reconditioned.

通常在标准条件下交付的额定容量；大于额定容量的值，这是一个最小值。永久丧失电池容量的能力 “完全形成，作为新的”值，在标准的额定条件下测量，这是不能通过修复恢复的。规格表中显示的额定容量容量值。最低驱逐 当一个新的，但完全形成的电池是在标准条件下测量的。C汇率的基础。请注意，额定容量取决于所使用的标准条件，这些条件可能与ba不同。 用陶器换电池。放电后剩余容量。在开路休息期间后保持电池内的容量。自我放电的结果。标准C 在标准条件下测量不透明细胞容量。在小区被修复时恢复的小区容量的暂时丧失。

Cell

Electrochemical unit, composed of positive and negative electrodes, separator, and electrolyte, which is capable of storing electrical energy. When encased in a container and provided with electrical terminals, the cell is the basic "building block" of a battery. Although the capacity of the cell is determined by its size, the cell's voltage is strictly a function of the basic electrochemistry of the couple.

Cell Reversal

Reversing of polarity of terminals of a cell in a multi-cell battery due to over discharging.

Charge

Return of electrical energy to a battery.

Charge Acceptance

Willingness of a battery or cell to accept change. May be affected by cell temperature, charge rate and state of charge.

Charge Efficiency

Value obtained when the increase in dischargeable capacity of the battery is divided by the current input. A measure of charge acceptance. Also indicates

目前UPS供电方案主要有分散供电、集中供电两种。分散供电的特点是一台UPS为一台或多台负载设备供电。分散供电的好处是分散风险,不会因为一台UPS供电异常造成大面积停电;缺点是UPS分散布置,不便管理,而且布线不易规划。另一种是采用集中供电方案,由一套大功率的UPS供电系统直接对机房的所有负载供电。集中供电的好处是便于规划、管理方便、维护方便;缺点是如果UPS系统异常,容易引起大面积停电事故,此缺点可以通过采用各种并联构架来避免。因此,以上两种方案各有优缺点,目前的数据中心一般都采用集中供电方案,也集中了供电的风险。由于UPS并机数量有限制,而且当UPS系统并机数量超过4台时,其可靠性并不比单机供电系统高多少。当机房UPS装机总容量超过一定限度时,建议将机房按几期规划分成几个区域进行供电。规划时可以参考:单机容量不宜超过400kVA,并机数量不宜超过3台。
