ACS-Li Series 1~3kVA Online Tower UPS
ACS-Li Series 1–3kVA Online Tower UPS is a lithium-battery online UPS designed to provide continuously regulated sine-wave power with compact battery integration and intelligent battery communication.
Lithium battery platform: The series covers 1–3kVA with internal lithium-battery standard models and external-battery long-backup configurations.
Full active power: Output power factor of 1.0 allows full kW output across the rated capacity range.
Dual AC voltage platforms: Depending on model, output voltage options include 100–125Vac or 200–240Vac.
BMS-ready monitoring: RS232, optional USB/SNMP, intelligent slot, EPO, Modbus/RTU settings and RS485 BMS communication support lithium-battery monitoring.
Final configuration depends on AC voltage platform, capacity, internal or external lithium battery design, battery voltage, BMS protocol, runtime and project requirements.
