You are probably right. I have the question into the factory about the MX series. I don’t recall the output terminals indicating they were referenced.

I seem to remember because of the control circuitry.

Period. You choose the reference if you want one. If you tie the + terminal to chassis ground then the – terminal is the hot –48 VDC terminal. If you tie the – terminal to chassis ground then the + terminal is the hot +48 VDC terminal. If you don’t tie either to chassis ground, then you will have to have a common return bar that is on the opposite rail from your fuses and circuit breakers. From: TJ Trout Sent: Monday, November 26, 2018 3:40 PM To: AnimalFarm Microwave Users Group Subject: [AFMUG] Eltek Valere J series -48 or +48 I'm looking at the Valere series and I can't seem determine if it's +48 or -48, seems like it's +48 but I thought all the telecom stuff was positive ground. How do you go about powering negative ground loads from a positive ground power source? I'm assuming you can leave out the neutral and isolate the chassis? -------------------------------------------------------------------------------- -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
