The CyberPower Standby CP425SLG uninterruptible power supply (UPS) safeguards a home office PC and other electronics (monitors, printers, scanners, speakers, fax machines, CD/DVD players and iPods) from surges, spikes, sags, brownouts and other power abnormalities. Its composite integrated circuitry offers advanced lightning protection. Patented GreenPower UPS advanced circuitry reduces UPS energy costs by up to 75% compared to competitive models. The CP425SLG unit has a capacity of 425VA/225Watts, eight (8) NEMA 5-15R receptacles, widely-spaced to accommodate transformer-based plugs. Its compact design allows for horizontal or vertical placement, or it can be conveniently mounted on a wall. This UPS has a maintenance-free, user-replaceable 12V/3.6Ah battery and offers connectivity via one (1) HID USB port and a serial-to-USB cable. Protection for phone/network (RJ11) is also included. EMI/RFI filters increase the immunity of the load to disturbances and surges. 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.
