200W 110V to 24V Isolated DC-DC Converter for Railway Onboard Equipment | MDB200-110S24

MDB200-110S24 200W Isolated DC-DC Converter

Input: 66–154VDC
Output: 24VDC / 8.33A
Rated Power: 200W
Application: Railway Onboard Auxiliary Equipment Power

The MDB200-110S24 is a 200W isolated DC-DC converter designed to convert a 110VDC railway power bus into stable 24VDC auxiliary power for onboard communication, monitoring and control electronics.

Its 66–154VDC wide input range accommodates practical voltage variations caused by battery charging, discharging and changing onboard loads.

Galvanic isolation creates electrical separation between the 110VDC input power domain and downstream 24V electronics, helping reduce interference coupling and supporting stable operation of communication gateways, monitoring devices, data acquisition units and controllers.

The 200W power capacity provides practical power for multiple 24V auxiliary loads in railway onboard systems.

Typical Applications:

Railway Onboard Equipment
Railway Communication Equipment
Railway Monitoring Systems
Communication Gateways
Data Acquisition Units
Railway Controllers
24V Auxiliary Electronics

Stable 24V Auxiliary Power for Railway Onboard Equipment

Railway vehicles may use a 110VDC power architecture, while onboard communication, monitoring, data acquisition and control electronics often require stable 24VDC auxiliary power.

The MDB200-110S24 converts a 66–154VDC input into regulated 24VDC/8.33A output, creating a dedicated isolated auxiliary power path between the railway power bus and sensitive downstream electronics.

Its wide input range helps accommodate voltage variations caused by battery conditions, charging, discharging and changing onboard loads, while galvanic isolation helps reduce electrical interference between the 110VDC main power domain and sensitive 24V electronics.

With 200W output power, the converter provides practical capacity for multiple auxiliary devices and helps engineers simplify the 110VDC-to-24VDC onboard power architecture.
