![]() The capacity of most battery backups, measured in VA (Volt-Amperes), is sufficient to cover the computer and the additional peripherals such as screens, speakers, and other external devices like a modem or router. Generally, battery backups for computers will offer about 2-4 hours of runtime, though this can vary depending on the load the system is under and how the battery bank is configured. OnLogic no longer recommends this type of UPS.The length of time a battery backup will last for a computer can vary depending on the model and capacity of the battery backup unit. The original post highlighted the use of an in-PC UPS. Note: This blog was originally posted on November 11, 2013. The time to think about a UPS for industrial computing before you need one! That’s a clear start for maintaining the life of a system, but UPSs are often an afterthought, or worse never thought of until a failure happens. When thinking about how to fail-proof your industrial system, especially in harsh environments, a good first step is to go fanless, and remove vents from a system. Are you running delicate and precisely calibrated sensor equipment? An Online UPS will prevent them from becoming inaccurate. Do you have an older manufacturing machine that occasionally blows a fuse? A battery backup will save you from losing data. Does your factory have an initial power draw when the line starts up? You will want a line interactive UPS to prevent damages to your PCs. It’s important to look at your use case and decide. Making the move to a UPS is sometimes a tough sell, at least before a disaster. UPS for Industrial Computing – how do you pick a mode? When the power came back on, they had to start over again from scratch. Normally racing against the clock, their productivity came to a sudden, grinding halt, and all work was lost. Along with the game went computers throughout the stadium, including those belonging to a photo vendor whoss photographers were processing photos for immediate release to international media. The primary downside to these is that the batteries can take more wear and tear and require replacement more frequently, but they are the best choice when system stability is at stake.Ĭase in Point: At the 2013 Super Bowl during the live telecast a massive power outage hit and shut the game down. In these UPSs, the battery is connected into the current constantly and, when power changes occur, there is no effect on output. Online/double-conversion – The Online UPS is a ‘must have’ when no variation in power can be allowed. ![]() However, the voltage adjustment can cause power momentary irregularities that can affect sensitive devices like medical equipment, precision measuring tools and the like. A line interactive UPS can sustain a continuous under voltage (brownouts) and overvoltage situations thanks to a an autotransformer that compensates without tapping the battery. Line Interactive – These UPSs are popular in areas where power fluctuates. This is fine for most PCs, routers, firewalls and the like, but can cause data errors if the machine is running a particularly intensive process, like rendering video. When power is lost, a switch triggers to bring the system onto battery backup – usually in a matter of milliseconds. Offline/standby – This is your most basic UPS, giving you surge protection and battery backup. They come in three general categories, or modes, each with their own purpose. But why is a UPS for industrial computing critical? And, with so many options, which option is best? What is a UPS?Īt the core, a UPS is a secondary power source - a battery - that connects to a system to take over in the event of a change in power. A Uninterruptable Power Supply (UPS) is a solution. Not to mention, the loss of valuable time. ![]() But what if the PC is operating on a factory floor or lies at the heart of a data logging, security, or medical embedded application? This can cause a loss of data and damage to sensitive equipment. What happens if your power goes out on your PC? Thanks to the work of Microsoft and Google, probably nothing. It’s a normal day, as you are reading this blog - your spreadsheets open, a design half finished, an email half written on another tab.
