APC Back-UPS 400VA, 120V, Flexible Mounting, Low Profile, Industrial, 3 NEMA outlets

The APC BV400XU is an uninterruptible power supply that delivers 400 VA or 220 W of backup power, giving essential electronics the time they need to ride through short outages or shut down safely. It provides protection that is simple to deploy and dependable, yet it occupies very little space, so it fits naturally under a counter, beside a workbench, or inside a crowded IT closet.

The housing is made of metal with a low profile that resists bumps and dust while freeing up valuable workspace. Built-in keyhole slots let you mount the unit flat against a wall or inside a rack enclosure, and the five foot input cord reaches standard outlets without the help of an extension cord. Three NEMA 5-15R outlets on the back panel support computers, network switches, point-of-sale terminals, or industrial controllers that cannot afford an unexpected shutdown.

This model keeps working in ambient temperatures from 0 to 50 °C, which makes it useful in warehouses, factory control rooms, and telecom cabinets where air conditioning is not always guaranteed. Front-panel LEDs show power status, battery condition, and fault warnings at a glance, so a quick visual check is all that is needed to confirm everything is running as planned.

A sealed lead-acid battery inside the unit offers up to fifteen minutes of runtime at half load and can be replaced in the field to extend service life. A surge rating of 300 joules adds another layer of defense against power spikes, and APC backs the Back-UPS with a lifetime equipment protection policy worth up to $75,000 for additional peace of mind.
