The parameters of multiple output power supply switch power supply module _

The parameters of the multiple output power supply switch power supply module, 2020-419 10 - 29 14:55:11 multiplexed output power supply design in order to eliminate the rack behind the clutter power adapter and towing line, multiplexed output power adapter should be designed to be simple and compact structure, high efficiency, stability, and to adopt multiple switch power adapter module. The voltage of the hierarchical network equipment, a total of 10 power adapter, in order to reduce the types of modules, so that future maintenance, must analyze the network equipment power supply voltage and classification, specific practices are as follows: (1) for network devices using switch power adapter, directly select the corresponding output voltage of the switch power adapter module power supply; (2) for the rectifier power network equipment and the regulated power supply adapter, all can use regulated power supply, in order to reduce the network voltage stabilizing circuit inside the equipment load, the guarantee is greater than the voltage circuit under the premise of minimum working pressure difference, as far as possible use of low voltage; (3) combination of regulated power supply adapter output voltage range, and than a standard voltage series switching power supply module, a list of multiple output power supply voltage level 5, 5 v, 8. 5V、15V、24V、48V。 Output because of determining the power adapter and network devices are placed on the rack layered, multiplexed output power adapter also USES standard case. According to the height of the rack, multiplexed output power adapter output because of 15 road, every road can output voltage level 5 at the same time. In order to make the output wire is concise, neat, multiple output power supply adopts air plug socket (8 core See figure 2) , including: 2 core power cathode; Because 5 v electric equipment is more, and current is larger, 2 core 5 v positive; The other 4 core as 8, respectively. 5 v, 15 v, 24 v, 48 v of the anode. Module selection is the core component of multiple output power supply switching power supply module, the pros and cons of its performance determines the stability, reliability, multiple output power supply. Through market research, and to consult with manufacturer's technical personnel, switching power supply module selection should follow the following principles: (1) products manufactured by domestic professional manufacturer of switching power supply; (2) the product through the international quality and safety certification; (3) the product model, implement the national standard size, so that the damage can be purchase to the same type of different manufacturer production products. According to the output voltage of the network equipment, power adapter, grading, adopted a 5 v, 8. 5 v, 15 v, 24 v, 48 v standard switching power supply module. The switching power supply module performance parameters are shown in table 3.
