Hi , do i can use RB 600 with -48v power? or Not?
Thanks for replays.

You *will* get +48Vdc if you flip the leads. The whole idea of "positive" and "negative" voltages has to do with the direction of current flow, not the absolute voltage involved. It also has nothing to do with wire gauges either - that only has an effect on the total series resistance of the power input (current limiting it if high enough). This is all about ground references, current flow, and wether the RB600 has an isolated power supply or not on it.do you have a volt meter ? connect the volt meter in reverse and see if you get +48. I would assume that as long as there is enough amps and you get +48 it should be fine. The only problem might be that if the negative wire is really fat and the positive wire is really thin, but if they are the same gauge it should be fine. I'm guessing it will be plenty beefy if it's for telecom equipment.
Recommended to use _isolated_ DC/DC converter or 48VDC/230VAC inverter.Hi , do i can use RB 600 with -48v power? or Not?
