Open frame power supply is an electronic device mainly used to provide stable power supply for various electronic products. As one of the core components of electronic products, the quality of open frame power supply is directly related to the performance and stability of the entire product. Therefore, choosing a high-quality open frame power supply manufacturer is crucial.Open Frame Power Supply of Shenzhen Kinri EnergyThere are many open frame power supply manufacturers in the market, but it is not easy to choose a manufacturer that provides high-quality products. At this point, consumers need to pay attention to some key factors, such as the reputation of the manufacturer, the quality and performance of the product, etc. Only by choosing a reputable and high-quality manufacturer can we guarantee the purchase of open frame power products that meet our needs.A high-quality open frame power supply manufacturer should have advanced production equipment and technology to ensure product...

The DC/DC power supply circuit has the advantages of low power consumption and high power, but at the same time, the conversion of the DC/DC circuit is completed through switching, which inevitably leads to the introduction of noise, specifically the ripple and noise of the power supply circuit.Compared with linear power supplies, switching power supplies (including AC/DC converters, DC/DC converters, AC/DC modules, and DC/DC modules) have the most prominent advantage of high conversion efficiency, generally reaching 80% to 85%, and up to 90% to 97%.Secondly, switching power supplies use high-frequency transformers instead of bulky power frequency transformers, which not only reduces weight but also reduces volume, making their application range increasingly wide.But the disadvantage of switch mode power supply is that its switching transistor operates in a high-frequency switching state, and the output ripple and noise voltage are relatively large, generally around 1% of the output v...
There is a difference in the number of output channels between single output power supplies and dual output power supplies, which determines their flexibility and applicability in applications.Single output power supplySingle output channel: A single output power supply has only one output channel, which can only provide one voltage and current output.Limited applicability: Due to having only one output channel, a single output power supply is usually suitable for applications that only require a single voltage supply, such as many simple electronic devices or systems.Simple design: The design of a single output power supply is relatively simple and cost-effective.Application scenario: In some relatively simple applications, such as household electronic products, some small communication equipment, or laboratory experiments, a single output power supply can meet basic power needs.Dual output power supplyMultiple output channels: A dual output power supply has two or more independent o...
There are several common malfunctions and causes of power modules:Unable to start or no output voltage: It may be due to abnormal or damaged input power of the power module, such as high or low input voltage, short circuit of input power, etc; It may also be an internal fault in the power module, such as a main circuit component failure, control circuit failure, etc.Large fluctuation of output voltage: It may be caused by excessive load on the power module, sudden load changes, and other reasons that lead to unstable output voltage; It is also possible that the internal switch components of the power module are damaged, the filtering capacitor is aged, and other factors can cause output voltage fluctuations.Heat dissipation issue: When the power module works for a long time or the ambient temperature is high, it may cause poor heat dissipation, which can lead to overheating or overload of the power module.Overload protection triggered: When the load current exceeds the rated current o...
Switching power supply is a type of power module. He is also a very common type of power supply, and the reason for adding the word "switch" is because its internal structure has a Schottky diode with switching characteristics. This diode has a high switching frequency and can quickly switch off thousands of times in a short period of time. And each time, it can provide power and current output, which plays an important role in general integrated circuits. However, in the use of Switching power supplies, intermittent oscillations may sometimes occur. What are the reasons for this? Next, Kinri will provide a detailed introduction to this issue for everyone.The reasons for intermittent oscillation in switching power supplies can be divided into three types: overload type, undervoltage type, and no-load type.1. Overload typeThis type of fault is more common among the four types of faults. Usually caused by breakdown of the rectifier diode on the secondary side of the switching transforme...
