This is true, however: 48V circuits are generally priced 'per-amp' just like 120V or 240V circuits. That translates into much higher cost-per-watt and with the efficiency of AC switching supplies being well over 90% you're probably better off from an economics point of view of getting the highest voltage supply that you can get and then to step down in your rack mounted devices. |
