  • Eight NEMA 5-15R outlets split between battery backup and surge-only protection
  • RJ45 10/100 surge protection shields ethernet datalines from spikes

Purpose and audience

The APC BE550G is a 550VA uninterruptible power supply with battery backup for desktop PCs, networking gear and peripherals. It provides 330W of backup power through four NEMA 5-15R outlets while four additional outlets deliver surge protection only. Ethernet dataline protection guards connected network equipment.

Input voltage window

The unit operates from mains voltages between 88V and 139V, switching to battery when the supply falls outside this range. Connected loads must not exceed the 330W rating or the UPS will overload. The 5ft right-angle NEMA 5-15P cord plugs into a standard wall socket and the chassis can be wall-mounted.

Build and connections

The replaceable battery uses the APCRBC110 cartridge, sold separately, allowing service without replacing the whole unit. Eight total outlets separate critical devices from non-critical ones. Bundled Windows power-management software enables automated shutdown; Mac users rely on the native Energy Saver settings.

Questions about this item

Should I choose the 550VA model or a higher capacity unit?

This unit delivers 550VA and 330W of battery backup power, suitable for protecting a desktop PC, monitor and networking gear during short outages.

What does 330W mean when my computer is running?

The 330W rating is the maximum real power the battery can supply; if your connected equipment draws more, the unit will shut down to protect itself.

What input voltage range does the UPS accept before switching to battery?

The UPS operates from mains between 88 and 139 volts; outside that range it transfers to battery backup automatically.
