The CyberPower ECO Series EC550G uninterruptible power supply (UPS) safeguards PCs and other electronics (monitors, cable DSL/ modems, and VoIP routers) from blackouts, brownouts, surges, spikes, sags, and other power abnormalities. Its composite integrated circuitry offers advanced lightning protection. Patented GreenPower UPS advanced circuitry reduces UPS energy costs and is an ENERGY STAR listed product. The CyberPower EC550G has three surge protected ECO outlets. When ECO mode is on and the battery backup detects that your computer is off (or in Sleep mode), computer peripherals connected to the ECO outlets will be turned off (USB connection required). This provides additional reductions in power usage and greater energy savings. The EC550G unit has a capacity of 550VA/330Watts, eight (8) NEMA 5-15R receptacles, including, 3 ECO mode outlets, and two (2) widely-spaced outlets to accommodate transformer-based plugs. Its compact design allows for horizontal or vertical placement, or it can be mounted on a wall. This UPS has a 12-volt maintenance-free sealed lead acid battery. Protection for phone/network (RJ11) is also included. EMI/RFI filters increase the immunity of the load to disturbances and surges. A HID compliant USB port provides connectivity to the EC550G. PowerPanel Personal Edition UPS Management software is included to monitor the vitals of the UPS and will safely shutdown the system in case of a power outage.
