Features and benefits of online UPS

From the time computers have been invented and become crucial store houses of information, the need to provide them with uninterrupted power has existed. With fluctuating power lines and blackouts that can occur at any time, one needs to safeguard their data and the computers from crashing from the sudden loss of power. For these reasons, UPS power was found as the alternative to keep computers running when power lines fluctuated or gave out. The concept of UPS has evolved since then and today it is seen as one of the reliable sources of power to all computers used in homes, offices and most importantly, for data centers.

The new concept of online UPS has arisen. Here the inverter supplies the full load all the time which means, the output is being regenerated completely inside the UPS. There is no transfer switch that is present which needs to be activated if the AC supply is cut off suddenly or there is a brownout that occurs. When  the UPS power supply matches these criteria, it is considered to be online UPS.

There are certain characteristics of online UPS. The first characteristic is that, the transfer time that is usually required by the traditional UPS power systems when there is an interruption in the power load is not present. The inverter supplies hundred percent of the load from the beginning. Hence, this kind of UPS usually supplies power that is conditioned and clean. The AC is converted to DC and then back to AC. Sinewave output is regenerated and added to the load. This kind of uninterrupted power supply makes sense for computers which need to be protected from different kinds of power supply problems. If the utility line power cannot be depended upon then the online type of UPS is recommended. This provides the ultimate protection and conditions the power supply accordingly.

When one uses online UPS the output voltage is well maintained even if the input voltage varies across a wide range. Many products are designed to provide consistent current flow without battery drainage. This is maintained even if the input voltages vary from 88 volts to as high as 136 volts.

Another feature of the online UPS is the bypass capability. This is provided on an automatic mode. It is a fail safe feature in order to provide back up power in case there is any failure within the UPS. This feature adds on redundancy and the single point of failure is removed. Hence, the possibility of loss of power to the load is reduced as a result. The system reliability feature is enhanced to a great extent. For these features this type of power supply systems are made crucial components in data centers. These places usually have servers, networks and other applications running 24/7. As a result, the power supply needs to be constant and consistent. The online UPS can ensure these properties. Hence, data centers make use of the online UPS systems widely and stress is on optimal use of power to save energy.
