The text explains how to design direct current (dc) power systems that operate at nominal voltages of 24 and 48 volts dc, use lead-acid batteries, and are installed in public network telecommunications systems and other exclusive-use environments. The 500kW PowerGate(TM) unit is rated for 95% efficiency at nominal voltage, a huge advantage for large power installations. These single output converters have a high current density of 46A per cubic inch -- occupying less real estate at the system level -- and can handle input voltages from 36V to 75V, with 48V as the nominal voltage. |
