DC DC converters are an integral part of many industrial and commercial applications. The VI-B6T-EX is a common type of DC DC converter designed by the knowledgeable professionals at VI Corporation. It takes the form of a square unit, typically measuring approximately 6 cm (2.36 inches) on each side. The VI-B6T-EX is designed to take DC input up to 60V, and output either polarity of 5V, 12V, 24V or 48V DC.

The VI-B6T-EX has a wide variety of applications. It can be used in areas such as television, radio equipment, audio and video equipment, automotive, security systems, medical equipment, telecommunications, computer peripherals, and instrumentation. It is also reliable and cost-effective for use in remote wireless and wired applications.

The working principle of the VI-B6T-EX is fairly straightforward. It consists of two main components: a power conversion section and a control section. The power conversion section of the converter includes the rectifier, DC-DC converter with a controlled output voltage, and two protection elements. The rectifier takes the AC mains voltage and converts it to a DC voltage. This DC voltage is then regulated by a DC-DC converter with an adjustable output voltage, which can provide either polarity of 5V, 12V, 24V, or 48V DC.

The control section is responsible for the regulation of the output voltage of the power conversion section, providing protection for the components in the converter. This section includes three elements that work together to provide the control needed for proper operation of the converter. The three elements are a PWM (pulse width modulation) regulator, a feedback circuit and a low-voltage cut-off circuit protector.

The PWM regulator’s function is to monitor the input voltage and adjust the duty-cycle of the current. This adjustment ensures that the DC voltage produced by the rectifier is maintained at a constant level throughout the operation of the converter. The feedback circuit works in conjunction with the PWM regulator, and is responsible for monitoring the output voltage of the converter. The feedback circuit controls the voltage produced by the converter, providing a stable DC output.

The low-voltage cut-off circuit works as a safety precaution for overvoltage and undervoltage conditions. It monitors the input voltage and responds by cutting off the output voltage if the input voltage exceeds the maximum limit or drops below the minimum limit. This ensures that the converter is not damaged by an undesired high or low voltage affecting the operation of the device.

The VI-B6T-EX is a highly reliable and cost-effective DC DC converter that is suitable for a wide range of industrial and commercial applications. Thanks to its carefully designed power conversion and control sections, it provides users with a convenient and efficient solution for their power conversion needs.
