Re: [AFMUG] MeanWell DR-UPS40 question

[Jesse DuPont]

For what it's worth, I don't think the DR-UPS actually has LVD built in. It was probably a coincidence that your Netronix shut off when the Battery Fail light came on because there was no longer enough current for the Netonix to run.You'd have to run the batteries (pos or neg) through a relay, with the relay operator terminals wired through the DC OK contact of the DR-UPS40, which opens when voltage goes below 21V (ish).

What's your DC power supply voltage output set to?
