Run time for load W
Run time for load
Enter the total load (power draw) of all devices to be protected by the UPS here. Based on the value entered we will estimate the run time that you will have during a total power outage. Adding run time increases availability by allowing the system to operate through longer outages without shutting down.
The total load (power draw) entered exceeds the maximum value for this product (260W)

Back-UPS Pro 420
High Performance Computer and Electronics UPS for Premium Power Protection
Back-UPS Pro Features & Benefits
Battery-protected and surge-only outlets
Reserves power capacity and run time for connected equipment that require UPS battery back-up while providing surge only protection for less critical equipment
Boost Automatic Voltage Regulation (AVR)
Preserves battery life and maximizes runtime by correcting low voltages without discharging the battery.
Battery and surge protected outlets
Back up and protect your hardware and data during power outages, surges and spikes.
Dataline surge protection
Provides protection of connected equipment from power surges on the data lines.
Surge only outlets
Protect secondary electronics from surges and spikes without reducing battery power used to run primary electronics during an outage.
Customizable voltage sensitivity
Toggle between pre-determined voltage-transfer points depending on your power quality (high, medium or low sensitivity), maximizing useful battery life and protecting sensitive electronics.
Customizable voltage-transfer points
Adjust the voltage points (widen or tighten the range) where your UPS transfers to battery to maximize useful battery life and protect sensitive electronics.
Patent-pending operating mode that bypasses unused electrical components in good power conditions to achieve very high operating efficiency without sacrificing any protection.
Transformer-block spaced outlets
Protect equipment with input transformer blocks without blocking access to other receptacles.
Boost and Trim Automatic Voltage Regulation (AVR)
Gives higher application availability by correcting low and high voltage conditions without using the battery (not available on all models).
Battery failure notification
Provides early-warning fault analysis on batteries enabling timely preventive maintenance
Periodic battery self-test ensures early detection of a battery that needs to be replaced.
Intelligent battery management
Maximizes battery performance, life, and reliability through intelligent, precision charging.
Provides temporary battery power when the utility power is out.
Simple battery replacement
Increases UPS availability by allowing quick, easy battery replacement.
Resettable circuit breaker
Easy recovery from overloads; no need to replace a fuse. (Not available on Wall Tap SKUs)
Provides notification of changing utility power and UPS power conditions
Disconnected battery notification
Warns when a battery is not available to provide backup power.
Use your PC to access additional power protection and management features for your UPS via a USB Port.
LCD Status Display
Provides key UPS status at a glance. Multiple status indicators with load and battery bar graphs.
Ensures the product has been tested and approved to work safely with the connected service provider equipment and within the specified environment.
