Entry-level computers
Gaming consoles

Personal electronics
Point-of-sale devices
Smart home devices

Home networking devices
Home entertainment systems
VoIP / PBX systems


Main Features
(4) Battery-Backed Outlets with AVR Function and Surge Protection
These outlets keep critical electronics online during a temporary blackout, adjust minor voltage fluctuations, and offer protection from power surges and voltage spikes.

If a blackout occurs or a power disruption beyond the tolerance range is detected, the UPS will switch over to battery power and supply these outlets with power. Connect mission-critical electronics to these outlets.

(4) Surge-Protected Outlets
Connect non-critical equipment to these outlets to protect the equipment from power surges and voltage spikes.

Automatic Voltage Regulation (AVR)
Automatically boosts or bucks minor voltage irregularities instead of switching to battery backup mode. By regulating the output voltage rather than using the battery, the UPS prolongs the lifespan of your battery and protects connected equipment against spikes, surges, brownouts, minor overvoltages and under voltages, and temporary blackouts.

The more boosts and bucks there are, the wider the acceptable input voltage range is, which will decrease the need to switch to battery power, therefore prolonging the lifespan of your battery. This series offers a two-step boost and one-step buck AVR functions.

Overload Protection
Protects the UPS from an overload. If the circuit breaker trips, unplug a few electronics before resetting the circuit breaker and turning your unit back on.

Constant-Current Constant-Voltage (CC/CV) Charging System
The battery is charged at a faster rate when the battery level is low. The charging system then reduces the charging rate as the battery becomes fully charged to avoid over-charging the battery.

Cold Start Capable
Turn on the UPS even without utility power as long as there is sufficient battery power.

Auto-Restart During AC Recovery
Once power returns to normal and the battery levels are sufficient, the UPS will automatically restart.

Off-Mode Charging
The UPS continues charging the internal batteries when powered off as long as the unit is plugged into an AC mains wall socket.

LED Status Indicators
LEDs illuminate to indicate different UPS power conditions.
