The -48 Vdc power consumption is the maximum total power that the H2TU-C-388 consumes or draws from the shelf power source. This parameter is needed when the H2TU-C-388 is in a location remote to the CO it is serving. It determines the battery capacity required to maintain an 8-hour, standby battery reserve for emergency situations. -
