Abstract:
1. An apparatus, comprising: a line side configured to receive power from an external power source; a circuit on the line side configured to send a first signal to at least one installed module the circuit comprising an analog to digital converter for receiving the response to the first signal; an isolated side isolated from the line side, wherein the at least one module is located at the isolated side; an isolation barrier between the line side and the isolated side to provide isolation between the line side and isolated side; wherein the circuit on the line side is configured to send the first signal across the isolation barrier to the isolated side; wherein the circuit is configured to determine a power requirement for the at least one installed module based upon a response to the first signal; and wherein the circuit is responsive to determining the power requirement for the at least one installed module to send a second signal to the external power source, the second signal comprises data representative of the power requirement.
