The purchase of 24V power supply should be cautious(2)
reasonable core structure and compact structure.
At the same time, in order to reduce the size of the module switching power supply, the switching frequency of the module switching power supply should be increased as much as possible. If it is to be increased to about 500kHz or higher, the loss of the ordinary magnetic core material is very large, and the magnetic core is easily overheated and magnetically saturated, and even It cannot work normally, so the high-frequency magnetic core material with excellent magnetic properties must be selected in the module switching power supply.
1. Flame retardant properties can not be ignored
Mechanical equipment will generate a lot of heat energy during use, especially in the current market competition is intensifying, in order to improve their market competitiveness, many companies continue to strengthen production, 24-hour production has become the norm, if the flame retardant power module Insufficient performance, long-term work may cause the spontaneous combustion of the power module, which may bring huge losses to the enterprise. Therefore, the flame retardant performance must not be ignored when purchasing a 24V power supply otherwise it is very likely that the gain will outweigh the gain.
2. Insulation needs to be considered
The advent of the era of intelligence has led to more and more electrical equipment. In order to protect the reputation of the company and ensure the safety of consumers, the insulation problem must be considered when purchasing power modules. If the insulation of the power module is insufficient, it will be used for a long time. There may be leakage of electricity. Once a consumer is injured, it will have a serious impact on the brand image of the company, and it may even make a company slump and disappear from the market completely.
