The Liebert GXT MT+ series is a true online double-conversion uninterruptible power supply (UPS), available in 10 kVA and 20 kVA (3‑phase in, 1‑phase out) and 10 kVA (3‑phase in, 3‑phase out) versions, all with a 0.9 output power factor.

These units are designed to provide robust and continuous power for mission-critical applications such as data networks, small data centers, and VoIP infrastructure.

Key Features:

IGBT-based rectifier and DSP control for high efficiency and reliable performance.
Graphical LCD display for system data, alarms, diagnostics, and troubleshooting.
High conversion efficiency: double-conversion efficiency up to 90 %.
Active input power factor correction: 0.99.
0.9 output power factor, allowing better utilization of real power capacity.
Wide input voltage range (110–280 Vac) to tolerate voltage fluctuations common in many environments.
Configurable output voltage: 200 / 208 / 220 / 230 / 240 Vac.
Generator compatibility: wide input frequency range (40 Hz–70 Hz).
Extendable battery charging: 4-stage design to optimize battery life and performance.
Adjustable battery-charging current: up to 12 A (configurable in steps) depending on battery capacity.
50/60 Hz automatic frequency-converter mode.
Intelligent monitoring: standard RS232 / USB, plus optional RS485 / Dry Contact / SNMP management.
Inbuilt Over Voltage Cut‑off Device (OVCD) for protection.
