I live in Central Florida and power outage here was really rare, maybe a fast blink every 4 to 6 months. But, we started to experience more and more often. For the first time a fast blink happened in middle of a print. The A1 asked me if I wanted to continue printing, I said yes, the printing wen…

[image] user_3496031781: I read a lot about the A1 power consumption, and came to the conclusion that during bed warming up it may reach about 300W, during normal printing it may still around 70~90W. It means a medium range UPS for 600~800W (1100VA) can sustain the printer working for 30~60 minu…

Those UPS, the 600/800W is in fact 600/800Wh. I think all UPS states VA as the power in one hour with FP=1, it drops to 600~800Wh for FP less than 1. It depends on ambient temperature, if battery is 100% charged, etc.

You need a portable power station, not UPS designed for computer. [image] Is Ecoflow Delta 2 worth the money? Bambu Lab P1 Series Has anyone put Ecoflow Delta 2 to the test? How long can it power 3 P1S…? [image]

I like in Central Florida also… I have 6 printers hooked up to 3 UPS 650’s (2 printers each). Only once over the last 3 years has the power stayed off longer than the battery lasted…and the print came out fine. Now, it’s rare I have them all going at the same time, it might be 2-3. From my under…

VA = VoltAmps W = Watt Watt is a statement that is only true if the load is purely resistive. VA includes inductive and capacitive parts of a load and provides the real value. This becomes painfully obvious once you try to run a motor on a UPS… I installed UPS systems and I can you that it is n…

I have one for the computer also, I’m lucky if it lasts 5 min. But, it’s setup to put the computer asleep for hours…not shutdown.

Think about a car battery, it may say 12V 250A, that is the VA, it is capable to supply instant 250A (motor start) on 12V, so that battery is 3000VA. Now, how long that battery can sustain 250A with 12V ? Maybe 20 attempts to start the engine when there is no fuel. Each attempt could be 10 second…

Hi, i know this isnt relavant to the topic but i want to make a general discussion( or thread) so how do i do it?

u forgot to write most important part. what ups you are using…
