It is highly efficient with up to 95% efficiency and is very reliable thanks to its built-in protections. This DC-DC converter can provide up to 300V output voltage with up to 150A output current. It is also capable of handling input voltage range of up to 700V, which makes it suitable for high-power applications.

In medical applications, the VI-21V-EX-F3 can be used to convert power from an AC power line to regulated DC power in medical devices such as patient monitors, imaging systems, and ventilators. In industrial applications, the VI-21V-EX-F3 can be used in applications such as servo drives, HVAC systems, and variable frequency drives (VFD) for motor control. It can also be used in entertainment applications such as studio light and sound systems. Furthermore, the converter provides overload, over current, and over voltage protection, making it suitable for a wide range of applications.

Working Principle

The working principle of the VI-21V-EX-F3 is quite simple. The converter takes in a DC input voltage, and with the use of a switching converter, it steps up or steps down the voltage to the desired output voltage. The switching converter uses transistors to switch the input voltage into the output voltage in a series of on and off cycles. The higher the frequency of the switching, the more efficient the converter is. The VI-21V-EX-F3 utilizes a high-frequency PWM switching converter operating at 200kHz to achieve maximum efficiency.

The VI-21V-EX-F3 also features safety protection circuits. These safety circuits detect any faults within the converter and shut down the output if a fault is detected. This helps prevent the damage to the load due to an over-voltage or over-current condition. The VI-21V-EX-F3 also features active current sharing, meaning that multiple converters can be connected in parallel, allowing for an increased current capacity per converter.

The VI-21V-EX-F3 DC-DC converter is a versatile converter that can be used in a variety of applications, from medical to industrial. Its wide input voltage range, high efficiency, and built-in safety features make it an ideal choice for a variety of applications. The VI-21V-EX-F3\'s ability to handle high load current and step up or down the voltage make it an ideal choice for a variety of applications.
