DC to DC converters have become a widely used power solution in the current electronic industry for transferring low power DC voltage from one source to another.
R2S-0505/HP-R models are the latest offering from DC to DC converter manufacturers, designed to provide a regulated output from a wide input voltage range. Understanding key features and principles of these models can help you decide if they are the right choice for your application.

Features
R2S-0505/HP-R models feature ultra-low noise levels and low power consumption. Their typical efficiency ranges between 83 percent and 89 percent depending on the input voltage. With the wide input range, these converters can be used in various applications. For instance, the usage of 12V, 24V and 48V DC power sources, such as from a solar panel, is now possible with the R2S-0505/HP-R converter. The maximum output power of the device varies depending on the selected voltage range: 15W at 5V – 24V in, 25W at 9V – 36V in and 35W at 18V – 75V in.

Another notable feature of the R2S-0505/HP-R model is its remote sensing and trimming capability. This makes it ideal for usage in noisy environments as the output voltage can be adjusted remotely, providing optimal performance. Additionally, this converter has built-in protection against over voltage, over load, over temperature, and short circuit. It is also RoHS compliant and UL/CUL certified.
The R2S-0505/HP-R converter model is also equipped with a wide range of output connectors, including PH/SMB/MIP and MH/CM/CMO/DIN, and is also available in bulk coil and cable forms.

Working Principle
The R2S-0505/HP-R DC to DC converter includes various components, such as a transformer, rectifying diodes, electrolytic capacitors, and a drive circuit. A switching power supply is used to turn on a semi-conductor switch when needed, and the output voltage is then regulated using current sensing and voltage feedback circuits.

The conversion process starts with a rectifier to convert the alternating current input into regulated DC current. This is then sent to a transformer to step up or step down the voltage before it’s sent to the regulator to regulate the output voltage.

The transformer is the most crucial part of the R2S-0505/HP-R DC to DC converter. The transformer is composed of a primary winding, a secondary winding, and a core with the primary winding connected to the input voltage, while the secondary winding is connected to the output voltage. The core provides an electromagnetic field to transfer energy from one winding to another. The transformer is designed to have the same number of coils on the primary and secondary windings, so the output voltage is just a transformed version of the input voltage.

The rectifier is used to convert alternating current into direct current, and is usually an alternating diode bridge. The bridge rectifies the voltage, and then an electrolytic capacitor smoothes out the voltage to produce a steady DC output. This is then sent to the transistor which controls the power to the regulator.

The regulator in the R2S-0505/HP-R DC to DC converter is used to maintain the output voltage at a constant level. It consists of a sensing circuit which senses the output voltage, and a feedback circuit which compares it to the desired voltage. When the two voltages are not equal, the feedback circuit sends a signal to the regulator to adjust the power supply to the output side, bringing the output voltage back to the desired level.

The R2S-0505/HP-R DC to DC converter is reliable, efficient, and suitable for many applications. With its wide input range and the ability to regulate output voltage remotely, this model is perfect for use in multiple industries.
