hi dear all
i really appreciate and thanks to ur support.
well i have another question dearssss
why we use DC -48 volt for telecom equipments instead of +48 volt DC.
and what impact really does on the equipment when we use same ground points for rectifier and inverter. i mean can we use any earth point same for AC and DC circuits.
