DC–DC converters are power-electronics circuits capable of arbitrary stepped-up, stepped-down and input/output voltage polarity conversions. REC3-2412DRWZ/H2/C/SMD-R is also a DC–DC converter, which is mainly used in 3 phase, full feature (3 phase Input, 3 phase Output) DC–DC converters. Its main application fields are such as the telecom power supply system for product line, communication base station, switch and routers and other IT application field. This article mainly talks about its application field and working principle.

Application Field

This type of DC–DC converter is mainly used in 3 phase, full feature (3 phase Input, 3 phase Output) DC–DC converter. Its working principle is combined ac/dc conversion and three-phase rectifying/inverting. Its main application fields are such as the telecom power supply system for product line, communication base station, switch and routers and other IT application field. Especially in a large number of complex server system, 3-phase input can help to reduce the output voltage ripple due to its strong power-supply capability. It also has the advantages of small size, high efficiency, high conversion ratio, high output power and long life.

Working Principle

The three-phase ac voltage is rectified to a direct voltage through 3-phase bridge rectifying circuit. The output voltage is adjusted by DC–DC converter and then output after filtering. REC3-2412DRWZ/H2/C/SMD-R has three levels of cascade with built-in MOSFET transistors. The first level is low-loss bridge rectifying and AC-DC conversion, then step-up and DC–DC conversion, and the last level is step-up and DC–DC conversion and voltage inversion. The effective input voltage is 230 VAC (180–265 VAC) and the output voltage is 24 V and 12 V. The peak power of output current is 12*1200 W. It is characterized by high efficiency, wide output voltage range and adaptive load capability.

Conclusion

In conclusion, REC3-2412DRWZ/H2/C/SMD-R is a 3 phase, full feature (3 phase Input, 3 phase Output) DC–DC converter. Its main application fields are such as the telecom power supply system for product line, communication base station, switch and routers and other IT application field. Its working principle is combined ac/dc conversion and three-phase rectifying/inverting. It is characterized by high efficiency, wide output voltage range and adaptive load capability.
