Those who deal with power supplies know that transformers may seem insignificant at first glance, but if they are not chosen properly, the entire equipment will suffer. There are many Switching Power Supply Transformers available on the market. Some have poor magnetic core materials, generating excessive heat during operation and unable to dissipate it effectively, resulting in a sharp decline in efficiency; others have substandard winding processes, causing whistling sounds as they are used, making the noise unbearable. Some manufacturers, in an attempt to cut costs, use extremely thin copper wires, which generate excessive heat when a large current is applied, and eventually burn out over time. To put it simply, many transformers do not take the actual working conditions seriously and only aim to lower the price. As a result, you have to replace the equipment frequently, which actually costs more.
The customers are also feeling frustrated. During the equipment debugging process, the temperature of the transformer kept rising rapidly and couldn't be controlled, so the power had to be reduced for operation. The production capacity was directly reduced due to this. When encountering large fluctuations in load, the output voltage was unstable, and the circuits at the rear end were also affected, causing the scrap rate to skyrocket. Moreover, those transformers with large size and heavy weight were difficult to install in the chassis and had problems with heat dissipation as well. In the end, what the power supply manufacturers need is a high-frequency transformer with low heat generation, high efficiency, good stability, and the ability to withstand long-term full-load operation. It is convenient and effortless.
Jiuli manufactures transformers in a different way. We don't engage in any fancy gimmicks. We simply focus on achieving the necessary capabilities of the transformer. This High Frequency Switching Power Transformer uses high-quality manganese-zinc ferrite cores, which have high magnetic permeability and low loss, generating less heat during operation and maintaining a stable high efficiency level. The winding is made with high-purity oxygen-free copper wire, which has good conductivity, low resistance, and does not heat up even when passing large currents. Moreover, our winding process is meticulous, with small inter-turn capacitance and excellent high-frequency characteristics, and there are no unexpected buzzing or interference.
When it comes to High Power High-frequency Transformer, many people think that higher power means larger size. But that's not the case. This Jiuli transformer achieves high power density and compact size through optimized magnetic core design and winding structure. With the same power output, it is one size smaller than similar products on the market. It can be easily installed in the computer case without taking up space, and the heat dissipation is also well managed. Moreover, each of our transformers undergoes strict aging tests and withstand voltage tests to ensure stable operation upon leaving the factory, without any failure halfway through.
Product Features :

3.Optimized magnetic core and winding structure, compact size and high power density, saves space when installed in the chassis, good heat dissipation and convenient arrangement.
Tips :
1.When choosing the type, don't just focus on the power. You also need to consider the actual working frequency and load conditions. If the frequency matching is incorrect, the magnetic core is prone to saturation, and the heat generation and efficiency will be affected.
2.When installing, pay attention to the cooling space. Don't pile up too much around the transformer. Leave a ventilation gap to effectively extend the service life.
3.If you find that the transformer has abnormal temperature rise or whistling sounds, first check the load and drive waveform. Don't rush to replace the part. Often, it is a problem with the peripheral circuit.
To be honest, the Switching Power Supply Transformer is not necessarily good even if it is expensive, but it definitely won't work if it is cheap. Jiuli doesn't engage in empty talk. They simply select the magnetic core well, use the copper wire properly, do the winding work meticulously, and conduct thorough testing. By doing so, you can spend one time on this, and use it for several years without worrying. This is truly a cost-saving and time-saving solution. Whether it is for communication power supply, industrial power supply, charging piles, or inverters, this transformer can firmly support it, making your equipment more reliable and durable.
