Abstract
A method and a remote device such as a sealed expansion module (SEM) for reducing power dissipation from an input power source in a telecommunications system are disclosed. A SEM contains a network feed monitor that receives an input voltage and current on twisted wire pair cables. The input voltage is then transmitted to a DC/DC converter and the voltage is adjusted and then transmitted to a BUS feed monitor connected to an active load. A first I2C device is connected to the network feed monitor to provide information related to input voltage and current to a main microprocessor that calculates input power. A second I2C device is connected to the BUS feed monitor and the active load to provide information related to the output voltage and output current to the main microprocessor that calculates output power. The main microprocessor is further connected through a third I2C device to a digital power manager that provides a DAC trim output to the DC/DC converter for optimizing the efficiency of the system.
