Advanced communication function:
Integrated Remote Management
Equipped with RS232 and optional SNMP/GPRS interfaces, the UPS allows full monitoring via PC or network. Compatible with major OS platforms and protocols (TCP/IP, SNMP, HTTP), it enables centralized control, even across distributed sites. Real-time data access, fault alerts, and remote maintenance simplify power system management at scale.
