How to Power 24V Equipment from a 48V DC System? MDC200-48S24 Isolated DC-DC Power Solution

In industrial control, communication equipment and automation systems, 48VDC is commonly used as the main DC bus, while PLCs, I/O modules, controllers and other auxiliary devices often require 24VDC power.

In real applications, however, a 48V bus may experience voltage fluctuations, load changes and electrical interference.

The MINGZINC MDC200-48S24 is a 200W isolated DC-DC converter designed to provide stable 24V auxiliary power from a 36–72VDC wide input range.

Why Use an Isolated 48V to 24V DC-DC Converter?

For industrial systems, DC-DC conversion is not only about changing voltage.

Galvanic isolation separates the upstream 48V power bus from downstream 24V equipment, helping reduce unwanted electrical interaction between different parts of the system.

With 200W output power, the MDC200-48S24 is suitable for powering PLCs, remote I/O, industrial controllers, communication equipment and other 24V auxiliary loads.

Typical Applications

The MDC200-48S24 is suitable for applications such as:

Industrial Control Systems · PLC Cabinets · Remote I/O · Communication Equipment · Industrial Automation · Battery-Powered Equipment · Power Distribution Cabinets

For example, in an industrial cabinet with a 48VDC main bus, the MDC200-48S24 can provide an isolated 24V power rail for control and communication equipment.

More Than Just 48V to 24V Conversion

When selecting an industrial DC-DC converter, engineers should consider more than input voltage, output voltage and power.

Input voltage variation · Load changes · Electrical isolation · Operating environment

A suitable DC-DC converter should not only convert 48V to 24V, but also match the actual power requirements of the complete system.
