Performance:
• Double conversion high frequency online design.
• Using digital control, the system is more stable.
• With input power factor correction (PFC), the input power factor is 0.99.
• The number of battery cells can be set according to user needs: ±16/17/18/19/20 cells.
• With parallel interface, 4 units can be paralleled, and battery packs can be shared in parallel.
• The charging current can be set, and the three-stage charging management of constant voltage, constant current, and floating charge can be automatically switched.
• With LCD and LED dual display, users can intuitively understand the working status and parameters of the UPS.
• With a maintenance bypass switch, which can be maintained when the power is uninterrupted.
• The output load capacity is strong, which can adapt to the unbalanced three-phase load.
• With RS232 communication interface and SNMP (optional) card.
• With emergency shutdown (EPO) button interface, in an emergency, press the EPO button to emergency shutdown.
