100W 48V to 24V Isolated Waterproof DC-DC Power Supply for Industrial Computers

2026-04-02

In industrial computers (IPC), embedded industrial control hosts, and edge computing devices, a stable 24V DC power supply is essential for the reliable operation of motherboards, power management modules, interface boards, and peripherals. However, in real industrial environments, 48V DC bus systems are widely used, often accompanied by voltage fluctuations, surge interference, high temperatures, dust, and humidity. Under these conditions, ordinary power modules often fail to deliver long-term stable performance.

The MINGZINC MDA100-48S24 is a 100W 48V to 24V isolated IP65 waterproof DC-DC power module specifically designed for industrial control environments. Featuring a fully sealed aluminum alloy housing, it offers wide input range, electrical isolation, low ripple and noise, fast dynamic response, and efficient natural cooling, making it an ideal power solution for industrial computer systems that require stable and reliable 24V power.


Why Industrial Computers Need an Isolated 48V to 24V DC-DC Converter

In practical industrial projects, a 48V DC bus is a common power architecture, while industrial computers and peripheral modules often require 24V operating voltage. If a non-isolated step-down solution is used directly, surges and common-mode noise generated by motors, inverters, welding machines, and other industrial equipment can easily be transmitted into the industrial computer, causing:

  • System crashes

  • False triggering

  • Communication failures

  • Interface damage

For this reason, the standard design approach is to use a 48V to 24V isolated DC-DC converter, which provides electrical isolation and effective anti-interference protection at the power stage.


Typical Loads Powered by the MDA100-48S24 in Industrial Computer Systems

By converting 48V DC into stable 24V DC, the MDA100-48S24 can reliably power:

  • Industrial computer IPC hosts

  • Embedded industrial control motherboards

  • Industrial display terminals

  • I/O acquisition modules

  • Communication interface modules

  • Industrial sensing and control units

Its fast dynamic response helps handle sudden load changes and maintain a stable 24V bus voltage.

Core Technical Features Designed for Industrial Control Environments

Wide Input Range for 48V Industrial Bus Fluctuations

The module supports a 36–72VDC wide input range, making it fully compatible with standard 48V industrial power systems and field voltage fluctuations.

Wideband Input Noise Filtering and Low Ripple Output

It effectively suppresses high-frequency interference and spike noise, helping ensure stable operation of IPC motherboards and sensitive industrial electronics.

Input-to-Output Electrical Isolation

The high-isolation design prevents surges, common-ground interference, and industrial noise from entering the control system.

Fully Sealed Aluminum Housing with Efficient Heat Dissipation

The enclosure itself contributes to heat dissipation, enabling long-term full-load operation without requiring a cooling fan.

Fast Dynamic Response

Even under frequent industrial load changes, the power module can maintain a stable 24V DC output.


Comprehensive Electrical Protection Design

The MDA100-48S24 includes multiple protection functions:

  • Input undervoltage protection

  • Input overvoltage protection

  • Output overcurrent protection

  • Overtemperature protection

  • Input-to-output electrical isolation protection

These features ensure long-term reliable operation of industrial computer systems.


Why IP65 Waterproof Design Matters in Industrial IPC Applications

Industrial control cabinets and equipment are often installed in environments such as:

  • High-dust workshops

  • Humid or oil-mist production areas

  • High-temperature enclosed cabinets

  • Outdoor industrial control equipment

The MDA100-48S24 adopts a potting and fully sealed structure with an IP65 protection rating, significantly improving the stability and service life of the power module in harsh conditions.


Compliance with International Safety Standards

The product design complies with:

  • UL1950

  • IEC950

This helps end equipment manufacturers complete safety certification more efficiently.
