DC–DC converters are power conversion devices, usually seen in vehicles and industrial applications, that are used to regulate voltage and current levels. The R-78T12-1.0/FC-R is a specific model of DC-DC converter from the manufacturer XP Power, specifically designed for industrial applications. In this article, we will look at the application field and working principle of the R-78T12-1.0/FC-R DC-DC converter.

Application Field

The R-78T12-1.0/FC-R is a 12V, 3 Amp DC-DC converter and is suitable for a variety of applications such as industrial, commercial, and mobile. The input voltage range of the unit is from 9V to 36V. It also has a maximum input power of 43W, allowing it to handle a wide variety of power requirements. It has a high efficiency of up to 88% and a wide (2:1) operating temperature range of -40°C to 85°C.

The R-78T12-1.0/FC-R is also designed to be easily integrated into multiple systems due to its small footprint and low profile (1U) design. This makes the unit suitable for applications that need to conserve space, such as IoT or mobile applications. In addition, the unit has a low profile terminal blocks that make it easy to attach the wires to. It also has built-in overvoltage, overcurrent, and overtemperature protections that ensure the circuit is protected against sudden events.

Working Principle

The R-78T12-1.0/FC-R is a flyback-type DC-DC converter. This means that it uses an inductor, or a transformer, to store energy. The way it works is that when an AC voltage is applied to the input terminals, the inductor stores the energy in a magnetic field. This energy is then discharged in the form of an AC voltage out of the output terminals, thus producing a DC voltage.

The R-78T12-1.0/FC-R also uses a full bridge-type switching arrangement. This arrangement ensures that the input and output voltages are switched at a certain duty cycle. The duty cycle is controlled by the current-mode controller in the device. This ensures that the device is always in control and that the output voltage is always stable. It also helps to reduce the switching losses of the device.

In addition, the R-78T12-1.0/FC-R has built-in power factor correction (PFC). This means that it can be used in applications where power factor must be controlled due to regulatory requirements. PFC helps to reduce the total harmonic distortion in the power system and increases efficiency.

The R-78T12-1.0/FC-R is an efficient, easy-to-integrate DC-DC converter that is suitable for a variety of industrial, commercial, and mobile applications. With its small footprint, high efficiency, wide voltage range, and built-in protections, it is a great choice for those looking for a reliable power conversion solution.
