RECOM DC/DC converters for railway applications – compact, efficient, plug-and-play

Simpex presents the new RMD40-UW (40 W) and RMD75-UW (75 W) DC/DC converters for the railway market. The modules are specially designed for auxiliary systems with an isolated 24 V bus and offer simple plug-and-play integration without additional external circuits.

Key features at a glance:

• Wide range input: 24–110 VDC (11:1), compatible with all common nominal voltages
• Flexible output voltages: 24 V as standard, 12 V and 15 V coming soon
• High efficiency: >90%, enables operation without additional cooling at temperatures ranging from -40°C to +85°C
• Comprehensive protection: short circuit, overcurrent, overtemperature, overvoltage
• Plug-and-play features: Input reverse polarity protection, inrush current limiting, power-good signal, internal OR diode for redundant operation
• Certified & robust: EN50155, EN50121-3-2, fire protection class EN45545-2:HL3
• Compact design: RMD40-UW: 100×60×30 mm, RMD75-UW: 110×73×40 mm, connection via block terminals or cage clamp terminals with DIN rail mounting option
• Durable & reliable: High MTBF value, service life of up to 20 years (Class L4)

These characteristics make the converters ideal for use in demanding railway applications: they deliver stable performance, meet all EMC, safety, and fire protection requirements, and enable simple, low-maintenance system integration.

"Our DC/DC converters meet all relevant standards without additional components—a cost-effective, compact solution for reliable railway systems," explains Marco Kuhn, Product Manager DC/DC Plug & Play at RECOM.
