Can the BR900G-GR protect against power surges?
Yes, it provides 1080 Joules of surge protection for connected equipment.
What does the Automatic Voltage Regulation (AVR) do?
AVR corrects undervoltages (brownouts) and overvoltages without using battery power, extending battery life and providing clean power to connected devices.
How many outlets does the UPS have and are they all battery-backed?
It has 8 NEMA 5-15R outlets. Typically, some outlets are battery backup + surge protection, while others may be only surge protection. Check the model label or manual for exact configuration.
Is the BR900G-GR compatible with a generator?
It is compatible with generators that provide stable voltage and frequency (within ±3% of 120V/60Hz). Unstable generators may cause the UPS to switch to battery frequently.
How do I test the UPS and battery?
Press the Power On/Test button to start a self-test. The UPS will briefly switch to battery and verify functionality. The battery status is indicated by an LED or alarm.
Can I connect a laser printer to this UPS?
It is not recommended because laser printers draw high peak power. Connect them to a dedicated surge protector instead.
What is the typical battery life and how often should it be replaced?
Battery life is typically 3 to 5 years depending on usage and temperature. Replace when the UPS indicates battery replacement or fails a self-test.
Does the BR900G-GR support USB monitoring?
