Product introduction
The Mean Well RSD-30 series are reliable, compact 30 W DC-DC converters optimized for railway and transportation environments. Designed for rugged applications, these modules meet demanding standards like EN 50155 and EN 45545-2, making them ideal for use in trains, trams, metros, and other mobile systems. Their ultra-low 1U profile (just 25 mm height) ensures they fit comfortably into tight enclosures, while their wide input voltage capabilities and protective features guarantee dependable performance in challenging, vibration-prone environments.
Key benefits — what makes the RSD-30 series great
- Railway-grade reliability
Complies with railway standards EN50155and EN45545-2, ensuring safe operation under transport-system stresses. - Compact and space-efficient
With only 25 mm height (1U), it’s very compact for in-cabinet or on-board use. - Wide input range
The series includes models for 4:1 wide input ranges (e.g. 9–36 V, 18–72 V, 40–160 V), making it flexible for different vehicle supply systems. - Solid protection
Built-in protection against short circuit, overload, over-voltage, and input reverse polarity helps safeguard downstream equipment. - High isolation
Offers 4000 V DC I/O isolation, which helps in preventing noise coupling and ensures safe separation of input/output. - Robust thermal performance
Operates from –40 °C up to +70 °C, able to run in very harsh environmental conditions. - Easy integration
No minimum load required, convection-cooled (no fan), and LED power-on indicator simplify design and installation. - Warranty assurance
Backed by a 3-year manufacturer warranty.
More product details
- The RSD-30 series uses half-encapsulated construction,which helps with vibration resistance while keeping thermal performance good.
- It incorporates a constant-current limiting circuitto handle overloads gracefully.
- LED indicator helps to quickly verify “power on” status in the field.
- Cooling is done by free-air convection, so no moving parts or fans, reducing maintenance.

Difference between variants:
- The G, L, and H suffixes denote different input voltage ranges:
- G: 9–36 V
- L: 18–72 V
- H: 40–160 V
- Output voltages differ among models (3.3 V, 5 V, 12 V, 24 V) — choose based on your application rail.
- Current capacity / power is appropriate to each output (e.g., 6 A on 5 V or 3.3 V, less on higher output voltages).
