确定正确的UPS尺寸?
根据设备功耗和期望的备用时间选择UPS;更高容量的型号提供更长的备用时间,在产品页面上有详细说明。
效率比率
在UPS系统中,VA超过瓦特数,表明'效率比'(例如,0.8或80%)。选择一个输出瓦特容量为您设备总功耗20-25%的UPS以获得最佳性能。
UPS Runtime:匹配负荷和持续时间

对于UPS选择,考虑备用持续时间,该时间随设备功率使用量增加而减少。选择容量更高的UPS以满足更长时间的需要,并查看产品页面上的预估备用时间。

常见问题
一个不间断电源(UPS)为连接的电子设备提供可靠的电源保护。在断电或电压波动时,它为敏感设备提供清洁的电池备用电源和过电压保护。
UPS systems 保护 电子设备,如 电脑,网络设备,电视和 游戏机 免受 停电,电压 波动和其他 电源 中断 的 损害。

考虑设备的最大瓦特和伏安(VA)额定值。 UPS容量不应超过这些额定值。 瓦特衡量实际功耗,而VA代表潜在功率。

对于UPS和计算机,瓦特和VA评级可能会有很大的差异。功率因数,即瓦特与VA的比率,在UPS尺寸设计中至关重要。通常情况下,选择一个输出瓦特容量比附加设备所需总功率高20-25%的UPS。

运行时间根据设备的功耗而变化。更多连接的设备意味着较少的运行时间,因此只为关键设备提供备用电源非常重要。

特性從基本的(如用戶可更換的電池和僅限脈沖的插座)到高級的(如可調節的電壓轉換點和智能電池管理)各不相同。根據您具體的電源保護需求進行選擇。

UPS系统保护免受商业电力网的问题,包括天气造成的损害,如闪电、雪和洪水,以及设备故障和事故。
