F81DF is a DC-DC converter module for direct current to direct current power conversion. It is developed by the French company Steca and is suitable for applications in the industrial automation sector, renewable energy system, building industry and other applications. The features of F81DF include wide input voltage range, high efficiency, fast transient response, high power density and high reliability.

F81DF is a single-output DC-DC converter module, it can be adjusted by the isolation core switch corresponding to the output voltage. The input voltage range is 4.5V-18V (18V max). provides output voltage in the range of 5V-22V (22Vmax) with the adjustable range from ±1%. The output voltage can be adjusted without turning off the output power, so it is suitable for quick and easy adjustment during system testing and operation.

F81DF also has good efficiency, up to 94% with low heat generation and high power density. Low and medium power consumption converter can be achieved with small size and weight, very suitable for small space or limited budget application fields. The safety protections incorporated into F81DF offer reliable and secure operation in difficult-to-control applications. It provides output short-circuit protection, over-voltage protection and over-temperature protection.

The main working principle of F81DF is to convert the input DC signal into a controllable output DC signal. The input DC signal is fed to a voltage regulator circuit. Depending upon the load, the voltage regulator adjusts the output voltage across the filter circuit. The filter adjusts the magnitude and frequency of the output voltage according to the external load demand. The output voltage of the filter is then fed to the output terminal of the converter.

The main components of the F81DF module are the step-up converter, input filter, output filter, voltage regulator and microchip. The step-up converter receives the input DC signal and steps it up to the required output voltage as specified by the user. The input filter helps to reduce noise and other impurities in the input power signal. The output filter helps to regulate the AC output voltage and remove spikes and other transients and provide clean DC output power. The voltage regulator helps to control the output voltage and adjust it in response to changes in the load.

The microchip is responsible for controlling the DC-DC converter as a whole, receive the external signals which can adjust the output voltage of the converter in a desired range. It also monitors and provides protection against system overloads, short circuits, over voltage and over temperature. F81DF is ideal for applications that require high reliability, power density and efficiency, it is a great solution for many industrial and commercial applications.
