ECOmode

ECOmode
As a provider of UPS, we get a lot of requests for our data sheets. These documents are key to understanding the specification of a UPS and the work that it can do, but if you are a new purchaser of UPS you may not have heard some of the terms before.
In the latest post in our series on this blog, we’re looking at what ECOmode on a UPS is and how it works.

ECOmode is a function found on most modern UPS in one form or another, and is particularly pertinent to units operating under an online double conversion topology. The goal of ECOmode is to reduce the energy lost through the power conversion process of the UPS.

UPS can typically run at efficiencies of anywhere from 92-96%, but ECOmode can increase this up to 98-99%, so the energy saving found by engaging this mode is significant. This begs the question how is this energy saving achieved and why don’t UPS operate at this level of efficiency all the time?

Quite simply, ECOmode works by taking some of the online elements of a UPS offline. When ECOmode is engaged, the inverter and rectifier are bypassed. This greatly increases the efficiency of the UPS simply because it’s doing less work.

It’s important to note that whilst in ECOmode, the UPS is still able to protect from powercuts as, despite being bypassed, the unit is still monitoring the incoming supply of power and is able to switch to battery power almost instantly (a typical ECOmode transfer time is 10mS) providing your business with an uninterrupted source of power. However, we would recommend considering very carefully exactly what you want your UPS to be protecting you from before engaging ECOmode.
