In industrial computers (IPC), embedded industrial control hosts and edge computing devices, 24V DC power supply is the key to the stable operation of mainboards, power management modules, interface boards and peripherals. However, industrial sites commonly use 48V DC bus power supply, which is accompanied by voltage fluctuations, surge interference, high temperature dust, and humid environments, making it difficult for ordinary power modules to work stably for a long time.
Mingzi Technology MDA100-48224 is a 100W 48V to 24V isolated IP65 waterproof DC-DC power module designed specifically for industrial control environments. The product adopts a fully sealed aluminum alloy heat dissipation shell, which has the characteristics of wide voltage input, electrical isolation, low ripple noise, fast dynamic response, and efficient natural heat dissipation. It is particularly suitable for providing stable and reliable 24V power supply for industrial computer systems.
1、 Why do industrial computers have to use 48V to 24V isolated DC-DC power supplies?
In practical projects, the common power supply architecture in industrial sites is a 48V DC bus, while IPC and peripheral modules typically require a 24V operating voltage. If the non isolated voltage reduction scheme is directly adopted, the surge and common mode interference generated by equipment such as motors, frequency converters, and welding machines can easily lead to the industrial control host, causing crashes, misoperations, or interface damage.
Therefore, the standard practice is:
Use a 48V to 24V isolated DC-DC power module to achieve electrical isolation and anti-interference protection on the power side.
2、 Typical power supply objects of MDA100-48224 in industrial computer systems
