Many industries can benefit from investing in backup power systems. By doing so, your company can prevent money loss, time loss, and equipment damages. Typical backup power systems consist of a variety of parts that work together when the utility power has failed. While you may understand what a backup power system does, you may not know how it works. The process might seem complicated, but it is actually quite simple. Today, we are going to explain the parts of the backup power system, what they do, and how they work together to keep you out of the dark.
As soon as a power failure occurs, an Automatic Transfer Switch (ATS) transfers the electrical load from the failed utility power to the standby generator. This switch detects the outage and turns on automatically. The ATS is responsible for starting the backup generator and transferring the electrical load over until the generator reaches the appropriate voltage and frequency.
Meanwhile, the Uninterruptible Power Supply (UPS) keeps the power on long enough for the generator to reach those necessary operating levels. UPS systems are vital in industries like hospitals, where they cannot afford flickering lights or split second power losses. Without a UPS, surgeons could be operating blindly and machines keeping people alive could shut down. Thus, UPS systems serve a very important role. In addition, the UPS consists of a series of batteries, which it relies on to run.
In order for the UPS process to function properly, a rectifier must convert the utility’s alternating current (AC), into an electrically compatible direct current (DC). This allows for the UPS to keep the power on until the generator is ready to take over. Once the utility power has been restored, the ATS will return the load and shut down the generator.
So, while a backup generator is great to have, a full backup power system ensures your company an automatic and seamless supply of power the second an outage occurs.
