AC DC Converters

The SWG100-05-C-R is a specialized AC DC converter designed for extreme environmental conditions. It is a transformerless AC DC converter and is rated 45-60Hz, input voltage of 100-500VAC, and output voltage of 5-12VDC.

Application Field and Working Principle

The SWG100-05-C-R is designed for harsh industrial environments with high humidity, dust, temperature, and vibration. It is ideal for applications needing wide, total input voltage ranges and lower noise features. It also has a wide operating temperature range from -40℃ to +125. Its working principle is based on dual switch current feeders - two sets of switches are used in each phase.

The dual switch current feeders switch on and off within seconds, generating a quasi-sine wave current. This current is then fed through the inductance to the output, creating a low-voltage, high-frequency DC signal. This signal is then rectified by an externally connected rectifier. The rectifier produces low-ripple DC voltage and current.

Advantages

The SWG100-05-C-R is beneficial in several ways. It is a transformerless converter, enabling more efficient power conversion. It has high efficiency and reliability, and the allowable over-voltage feature reduces the inrush current, which improves safety. It also has an automatic peak voltage adjustment feature, which can adjust the peak voltage to the desired level. It also has a wide line input voltage range.

The SWG100-05-C-R also offers many protection features, such as input over-voltage protection, over temperature protection, and input under-voltage protection. The current limit output and output short circuit protection features protect against overloads and dangerous output short circuits. It also has a built-in switching frequency adjustment feature, which can be adjusted to reduce interference.

Conclusion

The SWG100-05-C-R is an advanced AC DC converter designed for extreme environmental conditions. It is a transformerless converter and is rated 45-60Hz, input voltage of 100-500VAC, and output voltage of 5-12VDC. It has many benefits over traditional converters including high efficiency, reliability, and over-voltage protection. It also offers a wide range of protection features to ensure safety.
