    ◆  先進(jìn)的DSP數字控制技術(shù)的應用，使UPS的性能更加穩定，品質(zhì)更加優(yōu)越。
    

    ◆  負載功率因數為0.8，適合用電設備的發(fā)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(huán)境非常惡劣的偏遠地區。
    

    ◆  可搭配發(fā)電機。
    

    ◆  冷啟動(dòng)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(huán)境監測器等。
