这些可并联的电池模块能够在数小时内缓冲电源故障。这样,过程或其中的各部分就可以连续运行,对测量值进行连续记录,并保持童心不间断。必须关闭的高性能工业 PC 会有略高的能量需求。尤其是大型机柜在关闭期间仍继续运行的情况。例如,DC UPS 可在机床生产、纺织领域、所有类型的生产线、灌瓶装置以及风力发电厂的障碍灯中使用。
通过串行或 USB 接口以及免费的软件工具,可方便地与 PC 通信。
采用 SITOP DC UPS 和电池模块的配置:24 V 缓冲可以保持通信、信号和传感器测量值。为减轻 UPS 上的负载,执行器直接从电源装置供电。
通过 USB 接口,可以将与不间断直流电源的状态有关的所所有消息传送到 PC(如 SIMATIC IPC)。也可以通过 USB 接口来配置 DC UPS。
SITOP DC UPS 软件为用户提供了一个免费工具,可用来监控和组态 DC UPS,非常容易使用。来自不间断直流电源的信号可在 PC 上进行处理。在监控模式下,不间断直流电源的状态显示在 PC 上。
发生电源故障时安全关断,并可自动重启 PC。也可以任意定义对不间断直流电源的不同运行状态的响应,因此可非常灵活地集成到各种应用中。

有关选择电池容量的重要信息:
应根据电池是新电池或未老化的电池的放电周期来选择电源缓冲时间,缓冲时间是在不低于 +25 °C 的电池温度下完全充电的电磁模块直至 DC UPS 关闭的时间。
电池老化会将电池寿命结束之前仍然可用的电池容量缩短到通常为新电池的原始容量值(1.2 Ah/3.2 Ah/7 Ah 等)的 50%,且内部电阻会增加。当在电池使用寿命结束时显示消息“电池电量 > 85%”(Battery charge > 85%) 时,可用电池容量仅为原始容量的大约 43% (50% x 85%)。
在电池 温度低于 +25 °C 时,可用容量会在 +5 °C 电池温度下另外下降约 30%,下降至大约剩余容量 43% 的大约 70%。此时容量仅为原始容量的大约 30%。
因此,在对装置进行组态时,必须选择明显更高的电池容量:可通过选择 1/(约 0.5)(大约等于电池容量的两倍)来补偿大约 50% 的容量下降(根据相关负载电流和相关缓冲时间的表)。可通过选择 1/(约 0.43)(大约等于电池容量的 2.33 倍)来补偿大约 43% 的可用容量。可通过选择 1/(约 0.3)(大约等于电池容量的 3.33 倍)来补偿大约 30% 的可用容量。
建议:
建议电池在达到电池预期使用寿命的一半时(容量降低至大约 50%)定期更换电池,而不是安装双倍电池容量,原因是,在达到电池预期寿命的一半(或略微超过一半)之前,容量不会下降到 100% 以下。通过在此点之后定期更换电池,由于老化,只能安装单倍电池容量(而不是双倍容量)(在电池模块成本方面,高于中间价格,但仅需要一半空间)。
若使用寿命过半之后更换电池,可不必考虑电池使用结束时较大的分散剩余容量范围,这一范围未由电池厂商精确确定(全部时间之后,很多电池会高于平均 50% 剩余容量,但很多电池会低于 50%,也就是说,即使安装双倍容量,使用寿命结束时老化的影响也不会可靠得到补偿,而只是获得一般程度的补偿)-> 若在超过预期使用寿命一半时更换,就会以很高的可靠性保持所设定的缓冲时间。
对于在较低温度(不高于 +25 °C)下储存且储存时间不长于大约 4 个月的电池,可假定有以下使用寿命,其在很大程度上取决于电池温度。
