In one embodiment, a power supply comprises: a conversion circuit that outputs an output voltage at a first end of a cable; a remote voltage sensor measures a load delivered voltage from a second end of the cable; a control logic, wherein the power conversion circuit regulates the output voltage based on a signal from the control logic; a current sensor that measures current flow through the cable; and a resistance measurement circuit that computes a resistance of the cable as a function of the load delivered voltage, the current flow and the output voltage. The control logic regulates the load delivered voltage based on a voltage drop calculated utilizing the resistance. The control logic detects a change in the resistance of the cable based on the load delivered voltage and dynamically updates a value of the resistance for calculating the voltage drop when the change exceeds a tolerance.

Systems and methods for power supplies with dynamic voltage drop compensation

Provided herein are systems, methods, and devices for controlling power to radio equipment that services antennas mounted on a structure, and disabling power to the same when either technicians are present or when the structure has tilted. The systems may include a main board comprising a processor and an isolation board located at least partially within the structure. The isolation board may be configured to transmit to the processor a signal when an input is received via a switch and periodically transmit an indication of an acceleration of the structure due to gravity in a selected axis. The processor may be configured to disconnect power to a radio unit servicing the antenna based on an occurrence of either receiving the first signal or determining that a tilt angle of the structure has exceeded a predetermined threshold for a predetermined period.
