YDC3320 H requires± 96/108/120 V DC, which is achieved by connecting 16/18/20 12V batteries in series.The YDC3320 H series UPS devices are high-reliability, three-phase systems designed with input and output voltage isolation. This feature ensures the protection of connected equipment from damage caused by electrical parameter fluctuations in the network. In the event of a power outage, these UPS systems seamlessly switch to backup power without delay. External batteries with capacities of up to 200 amps can be connected, enabling extended autonomous operation of devices. If needed, the UPS units can be connected in parallel, enhancing the system's overall capacity.Used for powering critical three-phase loads, such as industrial automation systems, servers and data centers, financial transaction systems, medical equipment, and more.Functional capabilitiesDouble ConversionPure Sine WaveZero Transfer Time to Backup PowerInterface: REPO, RS232, RS485, USB, SNMP/Dry Contact SlotN...
