MaxGreen MG-LI-KSP 3000VA Pure Sine Wave UPS

The MaxGreen MG-LI-KSP 3000VA Pure Sine Wave UPS delivers heavy-duty power protection, reliable battery backup, and pure sine wave output. Designed to safeguard sensitive electronics against power outages, brownouts, and severe voltage spikes, this high-capacity UPS is ideal for multi-monitor workstations, high-end gaming desktop PCs, networking racks, servers, and small business equipment. Handling loads up to 1800W, it ensures smooth operation without risking system crashes or data loss during sudden blackouts.

Pure Sine Wave Output & Wide Voltage Stabilization

Unlike basic modified sine wave units, the MG-LI-KSP 3000VA outputs a clean, pure sine wave waveform. This guarantees 100% compatibility with active PFC power supplies, delicate server hardware, and audio/video gear. Operating across an extended input voltage range of 115V to 300VAC, its internal voltage regulator automatically stabilizes erratic power levels without draining the internal batteries.

High-Capacity Battery Bank & Reliable Backup

Equipped with a powerful four-battery configuration (4x 12V/9Ah), the UPS provides approximately 7 to 20 minutes of continuous power under full load. This extended backup window gives users ample time to save critical work and perform safe system shutdowns. Built-in overcharge, over-discharge, short-circuit, and overload protection mechanisms prevent battery degradation and protect connected equipment.

Low-Noise Operation & System Monitoring

Engineered for office and home environments, the unit operates with minimal noise (< 40dB). An intuitive LED display interface coupled with audible alarms provides immediate status updates regarding battery charge levels, load usage, fault errors, and line mode operation.
