Tripp Lite AV550SC 550VA UPS 300W Battery Backup Surge Protector AVR
Utility lines fluctuate constantly, dropping low in the heat or spiking when heavy equipment starts up. We built this unit to steady that incoming feed and carry connected gear on internal battery long enough to save work. It sits neatly under a desk or alongside network hardware.
Price as our retail partner last listed it. They set it and they can change it, so the figure on their page is the one that counts at checkout.
- 4 AC outlets (including 1 delay-on outlet for router)
- Automatic recycle/reset button
- Auto-restart capability
- Regulated 12V DC output for 4 devices
- Complete surge/spike protection
How this one is built
Voltage regulation
Automatic voltage regulation trims high line conditions and boosts low voltage back to nominal levels. Connected gear receives steady utility feed without drawing down the internal battery during common sags.
Routed power outlets
A dedicated delay outlet holds back power to network hardware until the upstream modem syncs. That sequence helps your router grab a clean connection automatically after a brief utility outage.
Low voltage DC tap
Regulated direct-current output feeds auxiliary desk hardware directly from the chassis. It frees up regular outlets while maintaining steady current for small peripherals that run on direct current.
Signal line jacks
Coaxial cabling and telephone lines get the same surge suppression as the main AC plugs. The jacks sit along the housing to clean up transient line spikes before they reach modems.
