In industrial computers (IPCs), embedded industrial control hosts, and edge computing devices24V DC power supplyIt is crucial for the stable operation of the motherboard, power management module, interface cards, and peripherals. However, industrial environments commonly use...48V DC bus power supplyHowever, due to voltage fluctuations, surge interference, high temperature dust, and humid environments, ordinary power modules are difficult to operate stably for a long time.
Mingxin TechnologyMDA100-48S24 It is a product designed specifically for industrial control environments.100W 48V to 24V Isolated IP65 Waterproof DC-DC Power ModuleThe product adoptsFully sealed aluminum alloy heat dissipation casing,haveWide input voltage range, electrical isolation, low ripple noise, fast dynamic response and efficient natural heat dissipationThese characteristics make it particularly suitable for providing a stable and reliable 24V power supply for industrial computer systems.
Why must industrial computers use a 48V to 24V isolated DC-DC power supply?
In actual projects, the common power supply architecture in industrial sites is a 48V DC bus, while IPCs and peripheral modules usually require a 24V operating voltage. If a non-isolated step-down solution is used directly, the surges and common-mode interference generated by equipment such as motors, frequency converters, and welding machines can easily be transmitted to the industrial control host, causing system crashes, malfunctions, or interface damage.
Therefore, the standard practice is:
use48V to 24V Isolated DC-DC Power ModuleElectrical isolation and anti-interference protection are achieved on the power supply side.
