  • Keeps power running during brief outages to allow time for safe system shutdown
  • Protects up to 5 devices against outages, brownouts, overvoltages, surges and line noise
  • Automatically restarts when power is restored, saving you a costly site visit
  • Recommended for locations where temperatures range within 32° and 122° F
  • 3-year limited warranty


850VA/450W/120V Battery Backup for PCs and Retail Point-of-Sale Applications
The BC850R standby UPS system provides reliable battery backup and AC power protection against blackouts, brownouts, overvoltages, surges and line noise for computing, networking and point-of-sale equipment in retail, kiosks, food service, and light industrial environments. It’s easy to set up in minutes. Just plug the BC850R into a properly grounded wall outlet, press the power button and connect equipment to the UPS outlets. For easy access, the input power cable, outlets, power button and status LEDs are all on the same side.

Allows Time to Back Up Critical Files During a Blackout 
During short blackouts and brownouts, the BC850R switches to battery power to keep connected equipment running. This allows you enough time to save data and complete a safe shutdown in case of a longer outage. Incoming utility power keeps the user-replaceable VRLA battery fully charged, so backup power is always available. The BC850R restarts automatically once power is restored, regardless of battery charge level, saving you a costly site visit.

Premium Protection from Surges and Line Noise Helps Your Equipment Perform Better
Rated for 190 joules of surge suppression, the BC850R and its five NEMA 5-15R outlets protect connected devices from the harmful effects of power surges. The BC850R also filters out disruptive electromagnetic interference (EMI) and radio frequency interference (RFI) that can complete a safe shutdown.

Easy Preventative Maintenance and Initial Troubleshooting
The BC850R's self-test capability and user-replaceable internal battery can extend the life of the UPS and minimize disruption to operations. A resettable circuit breaker helps prevent dangerous system overloads.

Audible Alarm and Diagnostic LEDs Keep You Informed 24/7
An audible alarm and a red LED indicate a low battery or fault condition. A green LED indicates power and line/battery mode status.

Hardened Housing Compatible with Versatile Deployment Options
The rugged compact housing allows use in locations with uncontrolled temperature or humidity (operating temperature range: 32° to 122° F / 0° to 50° C). The BC850R’s small size is suitable for desktop or floor placement. Keyhole mounting slots on the bottom enable wall mounting and are spaced in a 100 x 100 mm VESA pattern for mounting to the back of a monitor with the included hardware. Attachment points allow installation on a shelf or beam with user-supplied cable ties. The five-foot power cord with NEMA 5-15P plug connects to any compatible AC outlet.
