RAC05-12DC/W

AC/DC converters are essential devices in many industries and applications ranging from household electronics to telecommunications. The RAC05-12DC/W is a commonly-used AC/DC converter specifically designed for use in devices that require high ratings. It is a sealed, full-bridge, non-isolated DC/DC converter that is well-suited to a variety of applications that require reliable and efficient power conversion. In this article, we will take a look at the application field and working principle of the RAC05-12DC/W.

Application Field

The RAC05-12DC/W is designed to supply a continuous load of up to 200 watts and is ideal for use in a wide variety of devices, including cameras, medical devices, telecommunications, industrial automation, general-purpose electronic equipment, and portable electronic devices. It is very reliable and produces high-quality, low-noise output.

Working Principle

The RAC05-12DC/W features a full-bridge design that consists of four MOSFET devices that are arranged in a bridge configuration. This allows the converter to easily switch from AC to DC operation. The primary AC voltage is converted to low-voltage, high-frequency AC by an in-built power factor correction (PFC) circuit. This energy is then converted into DC by passing it through a full-wave bridge rectifier. The DC voltage is regulated by an on-board voltage regulator IC to provide a steady output voltage of 12V.

To ensure optimal power efficiency, the converter is equipped with an active PFC controller. This controller adjusts the current flowing through the MOSFET devices in order to optimize power conversion efficiency. Additionally, the converter has built-in short circuit, overcurrent and overvoltage protection circuits to prevent any damage to the device due to overload or abnormal conditions.

The RAC05-12DC/W also features an onboard fan controller which can be set to either 10% or 20% speed, depending on the required airflow. This helps to reduce the overall power consumption of the device by up to 25%. Additionally, the converter utilizes an advanced soft-start circuit to help reduce system noise during startup.

Conclusion

In summary, the RAC05-12DC/W is an efficient AC/DC converter that is specifically designed for high-power applications. Its full-bridge design and onboard protection circuitry make it a reliable and safe choice for a variety of applications. The onboard fan controller and soft-start circuit help to maximize power efficiency and reduce noise.
