Technical parameters

Excellent performance, simple appearance, perseverance, online double transformation design, DSP digital technology, illustrating the integration of cutting-edge technology and traditional products. It is the preferred product for small and medium-sized servers and computer rooms.

◆ 先進(jìn)的DSP數(shù)字控制技術(shù)的應(yīng)用，使UPS的性能更加穩(wěn)定，品質(zhì)更加優(yōu)越。

◆ 負(fù)載功率因數(shù)為0.8，適合用電設(shè)備的發(fā)展趨勢，帶載能力更強(qiáng)。

◆ 有源輸入功率因數(shù)校正（PFC），輸入功率因數(shù)高達(dá)0.98以上

◆ 寬輸入電壓頻率范圍極寬的輸入電壓和頻率范圍，適應(yīng)電力環(huán)境非常惡劣的偏遠(yuǎn)地區(qū)。

◆ 可搭配發(fā)電機(jī)。

◆ 冷啟動(dòng)功能。

◆ 零切換，有效保證了負(fù)載運(yùn)行的安全性和可靠性。

◆ 強(qiáng)大的監(jiān)控，標(biāo)配RS232通信接口和智能插槽，可擴(kuò)展 SNMP卡、RS485、AS400卡、EMD環(huán)境監(jiān)測器等。
