Your Fast Turnkey Solution: Cincon DC- DC CMFC(D)
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 is pleased to announce we’ve already expanded the range of chassis-mount modules CMFC(D) to include models with heatsinks. Unlike traditional heatsinks, our CMFC(D)-HS heatsink can be securely attached to the customer’s system case using screws. Also, we offer 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 you with more comprehensive power solutions.
CMFC(D)-HS and -HD excel in natural convection without extra aid：
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. Here is the 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 ℃.
Here is another 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 entire CMFC(D) series offers HS and HD models for you:
Cincon would keep releasing a variety of modules with different packaging and nominal input voltage ratings to meet the specific requirements of your applications. The table below illustrates the plug-and-play modular CMFC(D) series, which also includes HS and HD models. Recommended model selections are provided in the table, while detailed dimensions and Din-rail mounting suggestions can be found in the following diagrams.
