When to skip: Your equipment load exceeds BX1500M’s 1500 VA or 900 W rating. You need more than six battery-backed outlets from one of these units.
When the recommendation changes
  • If your equipment load exceeds the selected unit’s VA or watt rating, that unit is outside its published limits; above the BX1500M’s 1500 VA or 900 W rating, the load is above both models’ published ratings.
  • If you need a different number of battery-backed outlets, map devices by backup need before choosing.

Questions shoppers ask

How should I use the VA and watt ratings?

Check your connected equipment’s total load in both VA and watts. Keep each figure within the selected UPS’s published ratings; if either limit would be exceeded, choose another model or have the load assessed.

How many devices can receive battery backup?

The EC850LCD documents six battery-and-surge protected outlets; the BX1500M documents five. Count only the devices that need battery backup, then check the physical plug arrangement for your setup.
