Power Measurements on AC-DC Power Supplies
These circuits help shape the input current such that the input impedance of the power supply appears fairly linear to the power line, similar to a resistive load. By doing so, the problems of
The real data in terms of the power consumption and traffic load have been obtained from continuous measurements performed on a fully operated base station site. Measurements show the existence of a direct relationship between base station traffic load and power consumption.
For best results, aim for a reading where the digits are active and not all zeros. This gives better accuracy and makes the data more useful in analysis. For repeated testing in a fixed circuit, placing a resistor of known value in series with the load can be a convenient and effective technique for power supply current measurement.
If your product relies on stable voltage and current delivery, routine power supply current measurement should be part of your process—especially before deployment or shipment. The most common method for measuring current is to place a multimeter in series with the circuit.
Of the other base station elements, significant energy consumers are: air conditioning (17.5%), digital si gnal processing (10%) and AC/DC conversion elements (7.5%) . terms of three levels: co mponent, link and network. efficiency of the power amplifier. Efficiency can be improved using a specially designed power
