Fengchuang introduced low ripple laboratory power supply, and noise control reached the leading level in the industry

In the field of scientific research experiments and precision instrument testing, the ripple level of power supply is directly related to the accuracy of experimental data and the stability of equipment operation. The ripple interference of traditional power supply often leads to the deviation of experimental results and the decrease of sensitivity of precision instruments. With the persistent pursuit of technological innovation, Shanghai Fengchuang Industrial Co., Ltd. successfully launched the low ripple laboratory power supply, and its noise control performance reached the leading level in the industry, providing better and more reliable power solutions for researchers and laboratory equipment.

As a comprehensive national high-tech enterprise that has been deeply involved in the field of industrial electrical equipment for many years, Shanghai Fengchuang Industrial Co., Ltd. has always been driven by technological innovation since its establishment in 2010, and its products such as switching power supply, filters and transformers under the brand "Fengyun-Fonyun" have been widely praised in the market. Facing the strict requirements of low ripple and high stability of power supply in laboratory scene, Fengchuang R&D team deeply studied the pain points of the industry, invested a lot of resources in technical research, and finally created this breakthrough low ripple laboratory power supply product after numerous experiments and optimization.

There are many shortcomings in ripple control of traditional laboratory power supply. In the working process of ordinary power supply, due to circuit design defects and component performance limitations, large voltage fluctuations and noise interference will occur. These ripples and noises are undoubtedly fatal interference sources for high-precision experimental equipment, such as mass spectrometer and nuclear magnetic resonance instrument. For example, in chemical analysis experiments, ripple interference may lead to sensor signal distortion, resulting in large errors in measurement results; In biomedical research, unstable power supply may even affect the capture of weak bioelectrical signals by experimental instruments, thus affecting the accuracy and reliability of the whole experiment.

Fengchuang's low ripple laboratory power supply has achieved many major breakthroughs in technology. In the circuit design, a unique multi-stage LC filter circuit and advanced voltage stabilizing control algorithm are adopted. Multi-stage LC filter circuit can accurately filter ripple and noise in different frequency bands by carefully matching inductance and capacitance parameters; The voltage-stabilizing control algorithm monitors the change of output voltage in real time, quickly adjusts the output state of power supply, and ensures the stable output of voltage. The measured results show that the output ripple noise of the power supply can be controlled within the industry-leading 10mVpp, which is more than 80% lower than that of the traditional power supply, greatly reducing the interference to precision instruments.

In terms of material selection, Fengchuang also strives for perfection. The core components are high-performance products of internationally renowned brands, such as high-quality capacitors with low ESR (equivalent series resistance) and high-precision voltage reference chips, etc., to ensure the low ripple performance of the power supply from the source. At the same time, the internal wiring and layout of the power supply are optimized, which reduces the generation and coupling of electromagnetic interference and further improves the purity of the power supply.

In practical application, Fengchuang low ripple laboratory power supply has achieved remarkable results. After the power supply was introduced into a national scientific research laboratory, the signal stability of the high-resolution mass spectrometer used in the experiment was greatly improved, the data error rate was reduced by 60%, and the repeatability and reliability of the experimental results were greatly improved. The person in charge of the laboratory said excitedly: "Fengchuang's low ripple power supply completely solved the problem of unstable experimental data caused by power supply ripple interference for a long time, which provided a solid guarantee for our scientific research work."

With excellent performance and reliable quality, Fengchuang low ripple laboratory power supply has been widely concerned by scientific research institutions, university laboratories and precision instrument manufacturers once it was launched. At present, the product has established cooperative relations with many well-known scientific research units and enterprises. In the future, Shanghai Fengchuang Industrial Co., Ltd. will continue to increase R&D investment, continuously optimize product performance, introduce more innovative products to meet the needs of high-end application scenarios, continue to lead the development of power technology in the laboratory field, and contribute more to the progress of scientific research.
