Moreover, it is also used in industrial machinery, medical equipment and automotive applications. The V72B48T250BN3 is designed to be highly efficient, with an 85% efficiency rating. It is a 250W power supply that can support a wide range of input voltages, such as 3-72V. It provides 24V at 10A output voltage, enabling it to provide up to 240 W of power. Moreover, the device features over-current, over-temperature and over-voltage protection, making it suitable for a variety of applications.

Working Principle:

TheV72B48T250BN3 operates on the principle of a buck converter, commonly known as a step-down converter. A buck converter is based on the principle of pulse width modulation (PWM), which is a technique used for controlling the speed or power of an electrical device. In a buck converter, a MOSFET is used as a switch, while a capacitor works as a filter to smoothen the output voltage. An inductor is used for storing energy and generating the output voltage. The MOSFET is controlled by a PWM signal, which is generated by the microcontroller on board the power supply. This signal controls the frequency and width of the pulses, which are used to control the output voltage. The PWM signal is generated by a control loop, which monitors the output voltage and adjusts the pulses accordingly. This control loop ensures that the output voltage remains within the tolerable limits and is stable.

Conclusion:

The V72B48T250BN3 is a reliable and efficient device ideal for a wide range of applications. Its versatile design makes it suitable for consumer, industrial, medical and automotive applications. It is based on the buck converter principle and uses a PWM signal generated by an onboard microcontroller to maintain the output voltage within the specified limits.
