DC/DC converters are one of the most useful and versatile pieces of electronic equipment in the industry. They have a wide range of uses from replacing traditional, inefficient power supplies to being used in medical, military and industrial applications and most recently in the aerospace industry. The VI-21X-EU is a line of DC/DC converters from Power-One that are designed and manufactured for high performance and reliability in harsh electrical environments.

The VI-21X-EU is available in two different input voltage range models – 12V – 36V (VI-2112-EU) and 17V – 42V (VI-2117-EU). Both models feature wide input ranges and output voltage ranges of 1.0V to 36V with up to 600 watts of power. They come with a variety of features to enhance system performance and protect user devices. The VI-21X-EU is both UL 60950-1 safety approved and RoHS compliant.

The operating principle of a DC/DC converter is based on a switching system which enables them to convert input voltages from low to high or vice versa. They can also convert a direct current (DC) input voltage into a different output voltage, in order to match various electrical appliances, in this case the VI-21X-EU. The VI-21X-EU utilizes Step-down (buck) topology, which means it rectifies the input voltage and then turns it into a lower voltage. It also benefits from a continuous conduction mode (CCM) controller that operates on Pulse Width Modulation (PWM).

The precision level voltage control delivered by the VI-21X-EU is possible due to an analog type error amplifier, which is used to send voltage signals from the output to the PWM driver. The PWM signal ensures smooth, reliable noise-free output and the predictable efficiency of the power system. In addition to the error amplifier, the VI-21X-EU also has current limit and thermal shutdown protection, along with voltage muting for pre-charging capacitive loads, ensuring a safe and reliable power system.

The VI-21X-EU has applications in a variety of different industries. One of the most commonly used applications for the VI-21X-EU is telecommunications, specifically, providing power to cellular phone towers and antennas. They are also suitable for security systems, medical devices, battery charging and power protection, factory automation, and green energy applications. The VI-21X-EU is capable of delivering clean power reliably and efficiently in demanding environments, making them a great choice for any application.

In conclusion, the VI-21X-EU line of DC/DC converters is an ideal solution for many power electronics applications. The combination of high performance, reliability and clean, noise-free power make them a great choice for many industries. They can be used to provide clean power for applications ranging from telecoms to medical equipment, and their wide input voltage and output current ranges make them highly versatile.
