DC-DC converters, also known as DC-DC switches, are essential components in many electronic systems due to their ability to convert a higher DC voltage to a lower DC voltage. The VE-27T-EW-B1 DC-DC converter is one such component, and it plays an important role in ensuring the proper functioning of a variety of equipment.

Overview

The VE-27T-EW-B1 is a 28V DC-DC converter with a maximum power output of 27.5 watts. It is rated to operate over the full input voltage range of 9.6 – 30 VDC with no derating requirements. It is designed for general purpose and telecom applications, specifically those requiring a wide input voltage range, low standby power consumption and light load regulation accuracy. The output voltage is adjustable using an external resistor divider.

Features

The VE-27T-EW-B1 DC-DC converter has a wide variety of features that make it an ideal power source for a variety of applications. Its output voltage is adjustable from +12 VDC to +27 VDC. It is also protected for input reverse polarity, over-voltage, input over-current or short-circuit on the output, and over-temperature. Additionally, it is designed with a low standby power consumption of less than 5 watts.

The converter can operate in the temperature range of -40°C to +90°C and has an EMC standard of FCC Part 15 Class B. It is also RoHS compliant and offers high isolation between primary and secondary sides. This converter also offers a two-way built in transient voltage surge immunity.

Application Field and Working Principle

The VE-27T-EW-B1 is well suited for general purpose and telecom applications. It is commonly used in high-end HVAC systems, medical equipment, networking systems, security systems, power supplies, and other industrial applications.

The VE-27T-EW-B1 works on a switching concept, where the input current is converted to a higher DC voltage. This higher voltage is then regulated to the desired output voltage. This converter is designed with two transistors, along with diodes and other components, to provide power conversion and regulation.

The transistors used in the converter are configured as switches. When in the "on" state, a substantial amount of current flows through the switching transistor. This current is then rectified and passed through an inductance component, creating an output voltage. This is how the VE-27T-EW-B1 is able to convert a higher DC voltage to a lower DC voltage.

Conclusion

The VE-27T-EW-B1 DC-DC converter is a versatile power source with a wide range of features and applications. It is capable of converting a higher DC input voltage to a lower DC output voltage, and is designed with a low standby power consumption and multiple protection features. This converter is well suited for use in general purpose and telecom applications, specifically those requiring a wide input voltage range, low standby power consumption and light load regulation accuracy.
