No, I mean technically. Where to find the convertors and the rest of the hardware, how to design it... and of course, calculate costs and savings.
A lot of telecom and industrial network equipment runs on -48V DC, provided by batteries. Also, many server sites run the computers on high voltage DC, to eliminate the AC-DC and DC-AC conversions. You could probably modify a typical computer power supply for that, but you'd need a string of about a dozen 12V batteries to run it. Computer switching power supplies rectify the incoming AC and use the DC to run a power oscillator at a high frequency that's then passed through a transformer to be rectified and regulated at the desired voltage. In North America, that DC would be in the vicinity of 150V. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
