Product Pain Points and Selection Challenges


In the field of industrial communication and control, engineers face severe power design challenges. First, the industrial site environment is complex, with the standard 24V industrial power supply often disturbed by motor starts/stops and relay switching, causing voltage fluctuations far beyond expectations, which puts higher demands on the input adaptability of DC-DC converters. Second, industrial communication equipment is extremely sensitive to power supply ripple; CAN bus and RS-485 interface communication quality is directly affected by power noise, and excessive ripple will lead to data frame errors or even communication interruption. Furthermore, industrial control cabinets have limited space, and traditional brick-style power modules are too large to meet the compact layout requirements of DIN rail mounting. Additionally, industrial equipment needs to run 24/7 continuously, making reliability and thermal design of power modules critical to system stability. The MDA100-24S12 is precisely designed to solve these pain points as a 100W highly reliable industrial-grade DC-DC power module.

Typical Application Scenarios


CAN Bus and RS-485 Industrial Communication Interface Power Supply


CAN bus and RS-485 interfaces are the most mainstream communication protocols in industrial sites, widely used in PLC controllers, inverters, sensor networks, and other equipment. These communication interfaces have high demand for 12V power supply and are sensitive to noise. The MDA100-24S12, with its ultra-low 120mV output ripple, effectively ensures communication signal integrity and avoids data frame errors. Its wide 18-36V input range easily handles normal voltage fluctuations of 24V industrial power supplies, and the built-in π-type input filter circuit provides strong anti-interference capability to ensure stable communication.


Industrial Gateway and Protocol Converter Power Design


The development of the Industrial Internet of Things (IIoT) has spawned a large number of industrial gateway and protocol converter demands. These devices need to simultaneously power processors, memory, wireless modules, and communication interfaces. The MDA100-24S12's 100W output power provides ample power margin for various load combination configurations. The module's built-in input under-voltage/over-voltage protection can handle industrial site power anomalies, and dual-side wire exit design facilitates flexible wiring for engineers, shortening development cycles.


Industrial Control Cabinet Distributed Power Supply Solution


In large industrial control systems, the architecture of centralized power supply combined with distributed DC-DC converters has become mainstream. The MDA100-24S12's compact dimensions (116.4×65×22mm) and DIN rail mounting enable direct installation on control cabinet rails, achieving distributed power layout. Its high power density significantly reduces space occupation, and modular design facilitates maintenance and replacement, effectively improving industrial control system reliability and maintainability.


Rail Transit Vehicle-Mounted Communication Equipment Power Supply


Communication equipment in urban rail transit and railway systems needs to work stably under 24V train power supply systems. The MDA100-24S12 supports Mil Grade I (-40~+85°C) and Mil Grade II (-55~+85°C) temperature grades, meeting the strict wide-temperature operation requirements of rail transit vehicles. The module's comprehensive protection functions provide reliable power support for vehicle-mounted equipment, reducing equipment maintenance costs.


Selection Guide


When selecting power supplies for industrial communication and control equipment, it is recommended to focus on the following indicators: First, confirm whether the input voltage range covers the voltage fluctuation range of the actual working scenario; for 24V industrial systems, products with 18-36V input range are recommended; second, pay attention to output ripple parameters; for high-speed communication interfaces like CAN/RS-485, ripple below 120mV can effectively guarantee communication quality; third, select the appropriate temperature grade according to the application environment—outdoor or enclosed spaces recommend military-grade products; finally, verify whether the isolation voltage meets system grounding and safety requirements. The MDA100-24S12, with its comprehensive performance indicators and reliable protection functions, is an ideal choice for 12V/100W power supply needs in industrial communication and control fields.
