The rated power calibration of a power supply refers to the process of verifying and adjusting the power supply's output to ensure that it meets the specified rated power. This calibration is typically performed during the manufacturing or testing process to ensure that the power supply functions correctly and delivers the expected power output. To calibrate the rated power of a power supply, manufacturers use specialized equipment and techniques. Here are the general steps involved in the calibration process:
Setup: The power supply is connected to the calibration equipment, which typically includes precision voltage and current measurement devices. The power supply may be connected to a load bank or a simulated load to test its performance under different load conditions.
Verification: The calibration equipment measures the voltage and current output of the power supply while it operates at different load levels. These measurements are compared against the specified ratings provided by the manufacturer.
Adjustment: If any discrepancies are detected between the measured values and the specified ratings, adjustments are made to bring the power supply's output within the acceptable range. This may involve tweaking internal components, such as voltage regulators or current-limiting circuits, to ensure accurate power delivery.
Retesting: After the adjustments are made, the power supply is retested to verify that the calibrated output now meets the specified ratings. This step may involve repeating the measurements at different load levels to ensure consistent performance across the entire operating range.
Documentation: Once the power supply passes the calibration process, the calibration results are documented, including the measured values, adjustments made (if any), and the date of calibration. This documentation serves as a reference for quality control purposes and may be required for compliance with industry standards or regulations.
It's important to note that the rated power calibration is typically performed by the power supply manufacturer or a certified calibration laboratory. Regular calibration may also be recommended to maintain the accuracy and reliability of the power supply over time. About the power supply 's conversion efficiency
