Cincon Electronics Introduces Thermally Enhanced DC-DC Converters for Railway Applications

Cincon not only provides standard DC-DC converters but also offers the CMFC/CMFD series - an integrated power solution for diverse applications with built-in EMI filters, reducing your project development time. Additionally, Cincon has announced that they have already expanded the range of chassis-mount modules CMFC(D) to include models with heatsinks. Unlike traditional heatsinks, their CMFC(D)-HS heatsink can be securely attached to the customer's system case using screws. Also, Cinch offers a Din-rail variant type, the CMFC(D)-HD. The new ten series enriched the features of chassis-mount models for high-temperature and various scenarios, providing more comprehensive power solutions.

Due to the ingenious design of the heat sink, CMFC(D)-HS and -HD models are perfectly suited for reducing module temperatures in non-metallic enclosures. For installations on Din-rail in electrical cabinets, the Heat Sink with Din Rail (HD) is ideal, enabling flexible installation in high-temperature environments without derating and modular usage.

An Example with a Comparison Using the CQB50W8-36S Series

1. The common application method for CQB50W8-36S is PCB soldering. The derating curve is as follows

2. The common application method for CQB50W8-36S-CMFC(D) is attaching to a metal enclosure. The derating curve is as follows:

3. CQB50W8-36S-CMFD-HS(D) is a plug-and-play type combined with a heatsink without any other metal-assisted heat dissipation accessory. The HS and HD models exhibit exceptional load-bearing capacity at full load, even in high ambient temperatures of up to 87 ?.

Second Example of a Comparison from the CHB300-300S-CMFC(D) Series

1. CHB300-300S-CMFC(D) without heat sink and the derating curve is as follows:

2. CHB300-300S-CMFD-HS(D) without additional metal-assisted heat dissipation

3. CHB300-300S-CMFC(D) in direct contact with the external environment by attaching to the system enclosure (or heat sink). The derating curve is as follows:

The power converter modules come with additional accessories and installation methods, providing ease of installation and wiring, along with an integrated EMI solution. Cincon CMFC(D) series are well-suited for real-world product applications in various markets, particularly in demanding environments with fanless cooling conditions.
