Nowadays, DC DC power supply module is widely used in many fields, such as communication equipment, base station, user's power supply system, monitoring system and other equipment, industrial automation equipment and so on. So what is the DC DC power module, and what should we pay attention to when using it?
DC power module is a power module which transforms DC power into DC power supply. At this time, many people may ask, will DC conversion DC not be more than one stroke? In fact, in the daily use process, our current is not constant, sometimes need high voltage, sometimes need low voltage. The DC DC power module is to turn the high or low voltage current into the pressure we need. Its working principle is to convert DC power to AC power supply, it will convert AC power into the DC power we need.
In the process of daily use, because the DC DC power module is completed by switching oscillation circuit, it will also produce common mode differential mode noise interference. Therefore, in the process of using, we need to pay attention to the current value, preferably more than twice the input current value. The internal resistance of the power supply should be small, so as to reduce the consumption of DC. And in order to ensure that the power supply module has a strong reliability in the long-term work, it should work at more than 10% of the rated power, so as to avoid the voltage instability caused by the module trapped or slight output, which affects our work.
Many customers in the process of using the power module, is to achieve the isolation of power. Then according to different isolation requirements, we need to choose different power supply, and there is enough circuit distance between the output and input power supply in the design, so as to avoid weakening the effect of isolation.
