Battery backup and surge protection in one unit
AVR corrects low or high mains voltage without switching to battery, so the charge is saved for a real outage. When the power goes, the UPS switches to battery within 10 ms. Two RJ11 sockets protect a fax, modem or phone line, LEDs show the status, and audible and visual alarms flag problems. Protection covers short circuits, overload, lightning, and battery overcharge and deep discharge.
