DC DC Converters: REC5-4815SRWZ/H6/C/SMD-R Application Field and Working Principle

DC/DC converters are essential components in the power industry. A wide variety of DC/DC converters are available for various applications such as telecom, defense, automotive, and consumer products. REC5-4815SRWZ/H6/C/SMD-R is a type of DC/DC converter designed to convert a 48V DC supply into a regulated 15V DC supply. The product is aimed for use in telecommunication systems and cooling fan applications.

REC5-4815SRWZ/H6/C/SMD-R: Overview

REC5-4815SRWZ/H6/C/SMD-R is a 15W, 18A DC/DC convertermodule designed to convert a 48V DC input into a regulated15V DC output. The converter modulealso features a digital programmable output voltage. It is a SMD device designed to be mounted on a circuit board rather than a freestanding device. REC5-4815SRWZ/H6/C/SMD-R has a wide range of operational features, including overvoltage protection, undervoltage protection, input reverse polarity protection, over temperature protection, and short circuit protection. It also has a high efficiency of up to 90%.

How It Works

REC5-4815SRWZ/H6/C/SMD-R is based on a switching regulator principle. This type of converter uses a process known as pulse width modulation (PWM, to regulate the output voltage by controlling the duty cycle of the switching regulator.The primary side features a high frequency switching transistor and a primary coil that is energized when the switching transistor is driven to an “on” state. The current thus generated builds up a magnetic field in the primary coil. This magnetic field is transferred through the magnetic core to the secondary side where the energy is transferred to the secondary coil. On the secondary side, the output signal of the switching regulator is rectified by a diode bridge rectifier into DC voltage. The DC output is then filtered by an output capacitor which smooths out the ripple in the output voltage. The output voltage is further controlled by the PWM control circuit as mentioned earlier. This circuit determines the duty cycle of the switching regulator. The duty cycle is then adjusted to match the desired output voltage.

Applications

REC5-4815SRWZ/H6/C/SMD-R is mainly used in various telecommunication systems to provide regulated DC voltage. It is also used for cooling fan applications where it is used to provide the fan with low-noise operation and continuous power. The device is also suitable for use in medical equipment, process control systems, computer peripheral applications, instrumentation systems, and power supplies.

Conclusion

REC5-4815SRWZ/H6/C/SMD-R is a DC/DC converter designed to convert a 48V DC input into a regulated 15V DC output. It features a digital programmable output voltage, high efficiency of up to 90%, as well as advanced circuitry for overvoltage, undervoltage, and short circuit protection. The device is primarily used in telecommunication systems and cooling fan applications and is also suitable for use in various other applications such as medical equipment, instrumentation systems, and power supplies.
