Isolation transformers and rectification convert AC 220V/380V into DC power sources of 28V, 27V, and 28.5V.
2. The pre-stabilization control circuit utilizes imported components to pre-adjust and initially stabilize the output voltage of the isolation transformer, thereby reducing the power consumption of linear adjustment components, enhancing work efficiency, and ensuring a high precision and stability of the output voltage source.
3. The linear adjustment element finely adjusts the 28V DC voltage after filtering, ensuring the output voltage meets the required value and precision.
The filter circuit effectively blocks and absorbs the pulsating wave interference and noise from the 28V DC power supply, ensuring a low ripple, low noise, and low interference output voltage for the DC power supply.
The control system for the 27V DC power supply compares, judges, calculates, and analyzes various signals, then issues corresponding control commands, ensuring the overall stable voltage system of the DC power supply operates normally, reliably, and cohesively.
6. Auxiliary Power Supply and Reference Voltage Source: Provides a high-precision reference voltage source and power supply for electronic circuits required by the DC stabilized voltage system.
7. Voltage Sampling and Regulation: Measure the output voltage of a DC stabilized power supply and set the regulation of the output voltage of the DC stabilized power supply.
9. Current Detection Circuit: Obtain the output current value of the DC regulated power supply as information for current limiting or protective control.
10. Drive Circuit: A power amplification circuit set up to drive executable elements.
