DC DC Converters

A DC-DC converter is a device that takes a direct current (DC) input power source and outputs a different DC voltage. The output voltage may be higher, lower, or the same polarity as the input voltage. Different types of converters are used to provide various functions such as voltage regulation, voltage isolation, current limiting, power conversion efficiency, and frequency conversion. In some cases, depending on the function of the converter, the output voltage or current may also be adjustable.

The VE-21X-EU-F2 DC-DC converter is a DC to DC converter featuring dual input source and dual output voltage capabilities. The input source can be either a 12VDC or 24VDC power supply. The output voltage is adjustable from 8.0VDC to 17.5VDC. The adjustable voltage ranges allow the VE-21X-EU-F2 to be used in a variety of applications that require different power requirements.

The VE-21X-EU-F2 features an efficient buck-boost topology, which allows for maximum power conversion efficiency. A synchronous rectifier is also included to increase efficiency during light load conditions. The VE-21X-EU-F2 also features a wide operating temperature range of -40°C to +85°C, making it suitable for a wide range of applications, from harsh industrial environments to consumer electronics.

The VE-21X-EU-F2 is suitable for a range of applications, including industrial automation, programmable logic controllers (PLCs), LED lighting, point of sale systems, communications systems, machine tooling, robotics, and more. It is particularly useful in industrial applications where different outputs are required to operate electrical devices, such as PLCs and relays. The dual input capabilities also make it useful in applications where an AC or DC input source may be convenient, for example in a remote operation where only one type of power supply is available.

The working principle of the VE-21X-EU-F2 is based on the buck-boost topology. The input voltage is received and the output voltage is regulated by the buck-boost circuit. The input voltage is converted into high frequency alternating current (AC) and is then transferred into high frequency continuous direct current (DC) using a synchronous rectifier. The high frequency DC is then converted back into the required output voltage using a transformer and an output filter.

The VE-21X-EU-F2 also features a programmable output voltage that can be adjusted from 8.0VDC to 17.5VDC. This voltage output can be adjusted using a supplied potentiometer. The VE-21X-EU-F2 also features a soft start function, which gradually increases the output voltage when the converter is turned on, resulting in a smooth start without an abrupt current spike. This soft start function helps to protect electronic components that may be connected to the output.

In conclusion, the VE-21X-EU-F2 is a versatile DC-DC converter that is suitable for a wide range of applications. It features dual input source and outputs with adjustable output voltage, which allows for maximum power conversion efficiency. The VE-21X-EU-F2 is also capable of a wide operating temperature range, making it suitable for a variety of uses. The working principle of the VE-21X-EU-F2 is based on the buck-boost topology and the output voltage can be adjusted via the supplied potentiometer. The soft start feature helps to protect electronic components that may be connected to the output.
