Purpose and Audience

The Vertiv PST6-900LVMT is a 900VA/550W standby UPS designed for 120V environments. It provides battery backup and surge protection for office electronics, retail systems and networking gear. The unit includes eight outlets and USB-A plus USB-C ports for charging mobile devices. It suits users who need user-replaceable VRLA batteries and a three-year warranty.

Standby Topology Limits

As a standby UPS, it switches to battery power only after detecting a utility failure, so there is a brief transfer time during an outage. The 900VA rating caps the total connected load at 550W, and the 120V input restricts use to North American mains supplies. Models above 1100VA are not covered by this series, and lithium-ion variants stop at 400VA.

Pre-Installation Checks

Verify that your equipment draws no more than 550W combined and that all plugs fit standard 120V outlets. Confirm the intended location can accommodate the unit’s footprint and that ventilation is adequate. Ensure you have a USB cable if you plan to use the Power Assist software for automated shutdown. The VRLA batteries are hot-swappable, so plan for future replacement cycles.

Questions about this item

Should I choose the 900VA model or a lower-capacity VRLA option like the 500VA?

Choose the 900VA model when your connected equipment draws up to 550W; the 500VA VRLA units support lighter loads and shorter runtimes.

What does the 550W rating mean for the devices I can plug in?

The 550W rating is the maximum real power the UPS can deliver; the total wattage of all connected devices must stay at or below this figure.

What does the USB-C and USB-A charging provide in practice?

The USB-C and USB-A ports supply 5V charging current for phones, tablets or other USB-powered accessories during an outage.
