VE-2NJ-IU

DC-DC converters are one type of power electronic circuits often used in industrial applications and power systems. They are designed to convert input power into regulated output voltage or constant power when the load level changes. Both AC and DC power sources can be used, and the converted DC output is used for specific needs, such as providing power supply for load circuit, controlling motor speed, and stabilizing sensing and signal circuits. The output from DC-DC converters can also be configured for specific applications, such as a high pressure, high-current output, or a low-voltage, low-current output.

The VE-2NJ-IU is a DC-DC converter that provides isolated DC output and powered by external AC power. The VE-2NJ-IU provides up to 600 V DC output, can accept DC input power from 18 to 72 V, and includes a built-in EMI filter. With the internal PFC (Power Factor Correction) circuit, it is able to reduce power consumption and extend the life of the product. The VE-2NJ-IU is also equipped with multiple protections against overvoltage, surge, and short-circuit, making it more reliable and secure.

The working principle of the VE-2NJ-IU is mainly based on a full-bridge power factor corrected AC to DC rectifier, a Transformer and an LLC converter with high power factor. The full-bridge rectifier includes diodes and transistor switches, as well as passive components such as capacitors and inductors. It converts the AC power into DC power to the LLC converter.

The Transformer is used to isolate the LLC converter from the rectifier and to ensure that the output voltage level does not change significantly when the load current changes. The Transformer allows the output voltage to remain steady despite any fluctuations in the load current, thereby ensuring a stable DC power source. And the LLC converter converts the AC-DC power input into a regulated DC output.

The VE-2NJ-IU includes a PFC circuit to reduce power consumption. The PFC circuit helps to increase the overall efficiency by utilizing a large value capacitor such as film capacitors. This improves power factor, as well as reduce power losses throughout the device, resulting in improved efficiency. Moreover, the built-in EMI filter reduces wave and impulse interference, leading to better device reliability.

The VE-2NJ-IU is excellent choice for high-efficiency power conversion needs in industrial applications. It is highly reliable, featuring multiple protections against overvoltage, surge, and short-circuit. Furthermore, with the PFC circuit and the built-in EMI filter, it is able to deliver clean, low-loss, high-efficiency, and low-noise power output.
