Uninterruptible Power Supply U3 extended


Recommended Posts

Posted · Uninterruptible Power Supply U3 extended

Hello. I use a U3 extended at my work for prototyping purposes. Enough times now, a power outage has caused a print to fail, and valuable time to be lost. I was asked to look in to a UPS to stop these things from happening again.  

Does anyone have experience with UPS' and Ultimaker printers? Are they sufficient to stop a print from failing?  Thanks

    I remember a topic (but can't find it for now) where someone mentioned good experience with an UPS by APC for his S5, which gave him bridging time of about 30 minutes.

    I for myself (and my UM3) selected a quick and dirty (and a bit pricy) solution by using a power station with EPS function and 1000W power, which leads to a bridging time of at least 5 hours (calculating from the maximum power use of 200W; real consumption is about 120W). The external power brick of the UM3 is slow enough to deal with the short (30ms) switch time of the EPS.

    So your first consideration would be how long you usually have to ride out a power outage, so you know your need of energy, and then select a USV or a power station.

    I use a Delta2 from EcoFlow, but I know that other manufacturers also have similar power stations with EPS function available.
