MaxGreen MG-LI-EAP-850VA 850VA Offline UPS (Plastic Body)

The MaxGreen MG-LI-EAP-850VA is an offline standby UPS built to keep a single desktop PC, router or small network device running through a power cut, and to steady the supply when mains voltage wanders. It is the straightforward answer to load-shedding at a home desk or in a small office. It is rated at 850VA with a 460W load capacity, running from an internal 12V 9Ah maintenance-free lead-acid battery. Input and output are 220VAC at 50Hz, and the wide input range of roughly 140-290VAC lets it hold the output steady through the sags and surges of a stressed local supply rather than dropping to battery every time. Output on battery is a simulated sine wave, transfer time is 2-6 ms, and it runs quietly at under 40dB. The unit is designed in Singapore and assembled in China, in a compact plastic enclosure. It suits a single workstation: a desktop PC and monitor, or a router and ONU so the connection stays up when the lights go out. The point of a standby UPS is not to run through a long outage but to bridge the gap, giving you time to save your work and shut down cleanly, or keeping a modem alive through a brief cut. Give it clear air at the back, keep it off a damp floor, and it will sit quietly under the desk doing its job.
