ACS-LV Series 1–3kVA Lithium Online UPS

Name: ACS-LV Series 1–3kVA Lithium Online UPS
Rating: 4.5 (100 reviews)

Product Overview

ACS-LV Series 1–3kVA Lithium Online UPS is a single-phase online double-conversion UPS designed for reliable 100/110/115/120V AC power protection.

Full rated power: Available in 1kVA/1kW, 2kVA/2kW and 3kVA/3kW models with output power factor up to 1.0.

Lithium battery configurations: Supports multiple battery-voltage configurations with adjustable charging current for different backup requirements.

Stable power quality: Input power factor reaches ≥0.99, with pure sine-wave output, ±1% voltage regulation and 0 ms line-to-battery transfer.

Flexible deployment: Tower and rack configurations are available, with LCD monitoring, EPO, RS232 and optional USB, RS485 and SNMP communication.

Configuration and backup time vary by model, battery voltage, load level and installation requirements.
