Product Features

True Online Double-Conversion Technology

Delivers continuous, output-regulated power irrespective of input fluctuations—ideal for sensitive equipment requiring uninterrupted sine-wave power.

Wide Input Voltage Range & High Power Factor

Operates across a broad input voltage range (55 – 150 VAC or 110 – 300 VAC depending on load), with an input power factor of ≥ 0.99 at full load, ensuring stability and maximum compatibility with unstable grid conditions.

Zero Transfer Time & Pure Sine Wave Output

Guarantees seamless switching to battery during outages, while providing high-quality sine-wave power with ±1% voltage regulation for clean output.

Scalable Battery Options

Includes two 12 V/9 Ah batteries, with options for external long-run battery expansion, adjustable charging current up to 6 A, and full recharge to 90% in about 4 hours.

Intelligent Monitoring & Alerts

Features an LCD that displays load level, battery level, operating mode, bypass mode, and faults. Audible alarms warn for battery mode, low battery, overload, and system faults.

High Efficiency & Quiet Operation

Efficiency up to 88% in AC mode and 83% on battery; operates with minimal noise (< 50 dB @ 1 m), suitable for workspaces and server rooms.

Robust Protection & Connectivity

Built-in safeguards include short-circuit, overload, and fault protection. Optional connectivity for RS-232, USB, and SNMP enables remote monitoring and management across platforms.
