The G-ME UPS is a line-interactive uninterruptible power supply (UPS). Its main features are its advanced performance, reliability, high-efficiency, compact size, and understated design.

G-ME is a single-phase UPS, intended for use with nominal 220 ~ 240 Vac input. It is designed for use with desktop computers and other power-sensitive electronic devices. It filters the power from the utility line, reducing short-term voltage peaks and high-frequency noise.

In addition to its stable output voltage, the G-ME immediately provides power to its load when the utility power is interrupted or the utility voltage becomes too low.
The G-ME accepts a particularly wide range of input voltage, from 165 to 265 Vac, making it ideal for locations where the utility power voltage tends to vary.
The G-ME line is available in four models:  650 , 750, 1000, and 1500VA.
