FETA2500BA, 3000BA, 7000T, 7000ST!The power supplies can generate an auxiliary power (AUX: 12V0.15A) from CN1/CN2 to provide for remote ON/OFF and attachedcircuits.!AUX circuit is isolated from other (input, output, FG, RC, WRNand PG) circuits.!Please do not draw a current of 0.15A or higher from the auxiliarypower because doing so could damage the internal circuits orcause malfunction.When you connect a DC-DC converter, a current a few timeshigher than normal current may fl ow at start-up. Please check thecurrent.FETA-28
