Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to a PDU electronic control system. Background Art

[0002] The Power Distribution Unit (PDU) is an essential component in data centers, industrial automation, communication base stations and other scenarios, used for distributing and managing power supply. However, the design and performance of traditional PDUs have exposed a series of problems when facing modern high-density and high-efficiency requirements.

[0003] In the intelligent electronic control design of traditional PDUs, relays and other switching devices continuously consume energy to maintain their states during operation, resulting in an increase in the overall power consumption of the system and a decrease in energy use efficiency. In today's pursuit of green energy and sustainable development, this power-consuming design does not meet the requirements of energy conservation and emission reduction. At the same time, the circuit design is relatively complex, including a large number of connecting wires and components, which not only increases the manufacturing cost and failure rate of the system, but also easily generates overheating under high-load conditions. Overheating not only reduces the stability and lifespan of the equipment, but may also cause safety problems such as fires or short circuits. Moreover, as the current intensity that the PDU needs to carry continues to increase, the copper cladding of traditional printed circuit boards (PCBs) has become difficult to meet the requirements of large-current transmission. Although increasing the conductive ability can be achieved by thickening the copper layer or using copper bars, this not only increases the production cost, but also the temperature rise generated when large currents flow poses a threat to precision electronic components and shortens their service life.
