550 VA UPS
3 February 2010
Power Electronics / Power Management
APC has launched its Back-UPS RS 550 VA line-interactive uninterruptible power supply (UPS) offering energy efficient charging, shutting off power to computer peripherals when the computer is in sleep mode or hibernating, and three battery backup outlets with automatic voltage regulation (AVR). The UPS offers protection for business, office and home computer systems, as well as abundant battery backup power, allowing users to work through medium length and extended power outages. It also safeguards equipment from damaging surges and spikes that travel along utility, phone and network lines.
The UPS’s power saving AVR bypass capability is an efficient electrical design that consumes minimal power during normal operations and automatically bypasses the transformer until needed, saving power. Not only does APC’s PowerChute Edition shutdown software automatically power down a computer system in the event of an extended power outage, but the Back-UPS RS 550VA includes additional features such as audible alarms, LED status indicators, user replaceable batteries, pushbutton circuit breakers and plentiful outlets (including transformer-block spaced outlets).
The unit’s LCD display allows users to use the buttons to toggle through a variety of information regarding the UPS and the utility conditions. In addition, the Mute button performs two functions: pressing and holding it down disables all audible alarms (until the button is pressed again); while pressing and immediately releasing it silences the audible alarm for that specific alarm event only.
