Hello, I’m currently evaluating the HLK-10M24 and HLK-10M24B modules for an industrial IoT design, and I would like to better understand the differences between the standard 10M series and the 10MB series.
From the datasheets, both modules seem very similar in terms of output specifications, regulation (especially at 24V), protections, and general performance. However, I noticed that:
- The 10M24B version is smaller and lighter
- It has slightly higher efficiency
- In some distributors (e.g. LCSC), the 10M24B is significantly cheaper (
$2.8) than the 10M24 ($3.5)
Given these points, I would like to ask:
- What are the main design improvements in the 10M series compared to the 10MB series?
- Is the 10MB series based on a newer internal topology or integration level?
- Are there any trade-offs (e.g. EMI performance, thermal behavior, long-term reliability) that are not obvious from the datasheet?
- Is the price difference mainly due to manufacturing optimization, or are there internal design differences affecting cost?
Thank you very much for your support.
