DC-DC converters refer to devices that can convert the direct current (DC) of a power system to another DC of a desired voltage, frequency and power level by means of regulation and time basis. REC3-1212SRW/H4/A/X2 is a type of DC-DC converter with a wide range of applications and a modulated working principle.Generally, the REC3-1212SRW/H4/A/X2 DC-DC converter consists of rectifiers, filters, DC/DC converter, protection circuits, and digital controllers. Rectifiers are used to convert the alternating current (AC) of the power system to a direct current. Filters are used to reduce the ripple of the rectifier output voltage, which can improve the efficiency of the system and reduce electromagnetic interference (EMI). The DC/DC converter can convert the input voltage to a desired DC voltage by various regulating modes such as pulse width modulation (PWM), constant frequency pulse width modulation (CFPWM), or voltage-mode control based break-point regulating. Protection circuits can effectively protect the AC input from overvoltage, overload, or short-circuit, providing comprehensive protections for system safety. Digital controllers are adopted for both collection of input data and monitoring of control commands. At last, the output of the system is connected to the load through the voltage-regulated power supply.The modulated working principle of REC3-1212SRW/H4/A/X2 DC-DC converter takes full advantage of digital control and parallel processing. By means of bidirectional operation architecture, the current output of every single loop can be detected accurately and precisely. On the other hand, an improved isolated turning frequency modulation technique can realize remote control of frequency and voltage. Besides, the voltage peak can always stay on the desired value. As a result, with its outstanding reliability and stability, the digital closed loop control will be fully activated in order to realize a more effective regulation.The application field of REC3-1212SRW/H4/A/X2 DC-DC converter is wide and far-reaching. It can be used in battery charge and DC/DC converter systems, distributed power systems, telecommunications industry, medical industry, industrial process control, vehicles, aerospace, railroad, and ships. Moreover, due to its remote controlled regulating mode, REC3-1212SRW/H4/A/X2 DC-DC converter is able to fulfill the need for efficient power supply demanded by a large variety of small-scale distributed applications and multi-supply applications. The outstanding performance of REC3-1212SRW/H4/A/X2 DC-DC converter is achieved by its physical structure and its modulated working principle. The former creates a robust and precise physical structure while the latter effectively utilizes digital control assistants to improve system efficiency and reliability. In conclusion, REC3-1212SRW/H4/A/X2 DC-DC converter is a powerful and reliable power supply solution suitable for many different applications.
