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.

◆ 先進的DSP數字控制技術的應用，使UPS的性能更加穩定，品質更加優越。

◆ 負載功率因數為0.8，適合用電設備的發展趨勢，帶載能力更強。

◆ 有源輸入功率因數校正（PFC），輸入功率因數高達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，適應電力環境非常惡劣的偏遠地區。

◆ 可搭配發電機。

◆ 冷啟動功能。

◆ 零切換，有效保證了負載運行的安全性和可靠性。

◆ 強大的監控，標配RS232通信接口和智能插槽，可擴展 SNMP卡、RS485、AS400卡、EMD環境監測器等。
