Basically, battery backup systems solve the, either, you have one or two things. When the power goes out, either a generator is gonna kick in within five minutes, or 30 seconds typically. When the power goes out and then the generator comes back on, and lights everything up. But in that time span between the power going out and the generator firing, you need to keep critical equipment running.
Such as if it was a hospital, we don’t do a lot of hospital stuff, but if it was a hospital, you need to keep that emergency, those emergency systems working that are keeping life critical systems working, or to all field applications, you wanna keep your PLC running. You need to keep all your communications, you need to keep all your closing equipment working. You need to keep all that stuff operational and your alarms, your gas generator or gas detection systems, all running in between the power going out and the generator firing.
So typically, we would have, the backup can be sized for five minutes in that application, but, you would wanna size for like a four hour to an eight hour window, ’cause sometimes that generator, maybe it’s getting serviced. So then you wanna size for that application. So then you’re sizing for more of a four to eight hour application, even though the generator is gonna fires in five minutes.
But if the generator has a problem, at least you have eight hours to back up, running batteries, to keep that critical equipment running.
