UEI30-150-Q48N-C

DC-DC Converters are a type of electrical device used to convert a direct current (DC) voltage from one level to another. The UEI30-150-Q48N-C is an example of a DC-DC Converter, which can be used for a wide range of applications. This article will discuss the application field and working principle of the UEI30-150-Q48N-C.

The UEI30-150-Q48N-C is a wide input, dual-channel isolated DC-DC converter. This converter offers a very wide input voltage range of 9-36 VDC, so it can be used for both 12V and 24V systems. It is designed to operate from a single DC input voltage and provides two isolated output voltages. The two output channels are independently set from a stable output voltage range, providing a voltage of 5 to 48 VDC.

The UEI30-150-Q48N-C is a reliable and cost-effective solution for many applications, including: industrial automation, distributed power systems, factory automation, telecom, and UPS. It is especially suitable for telecom and distributed power systems because of its wide input voltage range and two independent output channels. In addition, it is fully compliant with various industry standards, such as EN50155, EN60945, and UL/IEC60950.

The UEI30-150-Q48N-C is designed to operate with high efficiency, up to 91%. It utilizes synchronous rectification technology and enhanced soft switching technologies to reduce switching losses and EMI / RFI emission to a low level. The converter also has integrated functions, such as overvoltage protection and short circuit protection, to ensure reliable operation in harsh environments.

In addition, the UEI30-150-Q48N-C has a unique feature called “Spread Spectrum Frequency Modulation” (SSFM). This feature uses a special modulation technique to reduce EMI emissions by spreading the switching frequency over a wide range. This helps to reduce the amount of electric and magnetic interference, ensuring uninterrupted operation of the system.

The working principle of the UEI30-150-Q48N-C is based on step-down DC to DC conversion. This involves the input voltage being transformed into a stepped down output voltage. The input voltage is passed through a high frequency switching circuit to reduce the voltage. This voltage is then passed through a transformer where it is converted to the desired output voltage and is regulated by feedback circuit.

Once the desired voltage is achieved, the UEI30-150-Q48N-C is able to operate efficiently with low ripple and noise, making it suitable for a variety of applications. It is also equipped with various safety features such as overvoltage, overcurrent, and short circuit protection, ensuring reliable operation. The converter also has built-in compensation to maintain output voltage accuracy.

In summary, the UEI30-150-Q48N-C is a high performance DC-DC converter suitable for a wide range of applications. It offers a wide input voltage range, two isolated output voltages and a range of features to ensure reliability and efficiency. The converter also uses Spread Spectrum Frequency Modulation to reduce EMI emissions, and is equipped with various safety features to ensure safe operation. Thanks to its working principle of step-down DC to DC conversion, the UEI30-150-Q48N-C can provide a reliable and cost-effective solution for many industrial applications.
