REC7.5-4815SRW/H2/A/M/SMD is a product of DC DC converters which is mainly used for intermediate bus voltage generation or voltage cascade power supply conversion in distributed power systems. The product has high conversion efficiency and is suitable for wide range of input voltage. According to its specified output voltage and current parameter, it can guarantee the intermediate bus voltage stability even when the terminal load changes. The product is widely applied in electronic equipments of computer, telecommunications, automobile, power system, UPS and military etc.

Working Principle

DC DC Converters integrate transformer, chopper, rectifier circuit, and control chip etc. The following is a brief introduction of its working principle:

1. When the input terminal is turned on, the power will be switched on and its output pulses will be sent to the integrated circuit.
2. The control chip set transition time, switching frequency and the corresponding parameters depending on the characteristics of the load.
3. The internal pulse signal will be sent to the switching tube, turning it on and off so that the transformer can be driven to work and transform the output voltage.
4. The transformer outputs the AC voltage which will be further rectified to a DC voltage, and then be output through the output port.

Application Field

DC DC converters are widely used in various fields, such as computer, telecommunication, power system, automobile, UPS etc. Among them, the most typical application includes:

• Automobiles: it can convert the 12V battery voltage into 24V which can provide more electric power for ABS control system, power steering system, air-conditioning system and also can stabilize the voltage of electric motors.
• Telecommunications: It is used to supplement the electric power output system for its wireless base station.
• Power system: It can convert 220V AC into DC which can support the power consumption of distributed power system.
• UPS: It can convert the 220V AC into 48V DC for UPS buffer and also dc ac to dc power supply transformer system.

Due to its small size and high efficiency, REC7.5-4815SRW/H2/A/M/SMD is getting more and more applications.
