Uninterruptible power supply (UPS) technology has changed quite a bit over the past several years, with newer devices offering far more intelligence and energy efficiency than previous generations. Electrical contractors charged with helping customers choose the right UPS for their various applications would do well to understand the various features and s that UPSs now provide – so they can help customers choose wisely.
Let’s start with energy efficiency. So-called “eco-mode” UPSs have been around for more than a decade, but only now are beginning to gain traction, thanks to some advancements in the technology. The idea is to reduce the power loss involved in the double power conversion process – from AC to DC and back again – that’s involved in “cleaning” utility power. In eco-mode, UPSs bypass that process most of the time, until it detects a power quality issue.
That technology never caught on in a big way because it took a few milliseconds for the conversion process to kick in – an unacceptable risk in many instances. A new form of eco mode gets around the issue by constantly running the power inverter, but stopping short of performing the full power conditioning and double conversion when it’s not warranted. However, because the converter is always running, it can kick in immediately when needed.
Schneider Electric calls this technology ECOnversion and finds it delivers efficiency that may occasionally drop below the 99% efficiency that’s possible with traditional eco modes, but sacrifices nothing in reliability.

Beyond the choice of operating mode, different UPS models come with various s that may prove useful depending on the customer application in question. Following are some common features to look for:
Which brings us to another consideration: battery options. Most traditional UPSs relied on lead-acid batteries to store power. They work well, but carry significant weight and take up quite a bit of space. Now Lithium-ion batteries are making their way to UPSs, offering far more energy storage in a much smaller space, at about 30% less weight. What’s more, they require far less maintenance than lead-acid batteries.
