DC DC Converters

DC-DC converters are electrical power converters that are used to create DC outputs from smaller DC voltages or AC inputs. They come in many different varieties and styles, including the V48C3V3C75B, and are found in a variety of industries.

V48C3V3C75B Application Field

The V48C3V3C75B is a dual output converter designed to connect to outputs of 48VDC to provide two isolated outputs of 3.3 volts. It is available in two different models, enclosed and modular. This makes it an ideal choice for a variety of applications including industrial controls, medical equipment, telecommunications, and power supplies.

The enclosure model is designed to fit within a variety of enclosures including those found in industrial equipment. This allows for a clean, easy to mount solution to an otherwise difficult problem. The modular model is designed to easily be used in several applications at once, allowing for quick side-by-side installation.

V48C3V3C75B Working Principle:

The V48C3V3C75B operates on a buck-boost switching topology. This means that it uses a step-up transformer to increase the output voltage level while simultaneously providing isolation from the input. The power switch then divides the transformer output into two isolated outputs. This allows for a precise level of output voltage control over a wide range of input voltages.

The power switch is controlled using pulse width modulation (PWM). This is done by varying the on/off duration of the switch in order to achieve the desired output voltage levels. In order to minimize interference from other devices, the converter incorporates EMI suppression circuitry.

The V48C3V3C75B also features an over-voltage protection circuit which limits the output voltage levels to prevent damage to the connected load. This is done by sensing the output voltage and limiting the input voltage when necessary.

Conclusion

The V48C3V3C75B is a versatile and reliable DC-DC converter designed to provide two isolated outputs from an input of 48VDC. It utilises a buck-boost switching topology which provides efficient protection from over-voltage and EMI interferences. The design is available in enclosed and modular versions which allow for flexibility in installation.
