## Summary description

MEAN WELL RSD-30L-12 is a 30 W power adapter/inverter designed to convert 18–72 V input to a stable 12 V output. It meets RoHS sustainability standards and is suited for automotive, industrial, and telecom applications requiring a compact DC-DC conversion. Dimensions: 60 × 113 × 25 mm. Pack quantity: 56 pieces.

## Long description

MEAN WELL RSD-30L-12 is a compact, enclosed DC-DC converter that converts a wide input range of 18–72 V DC to a regulated 12 V DC output at up to 2.5 A. Designed for demanding environments, this 30 W module provides high isolation between input and output and complies with railway standard EN50155 while meeting RoHS environmental requirements. Its small footprint (60 × 113 × 25 mm) makes it suitable where space is limited and reliable 12 V power is required.
Advantages
The converter delivers a stable 12 V output with 30 W continuous power in a compact metal enclosure, featuring 4000 V DC isolation between input and output for enhanced safety and noise immunity. Wide input flexibility (18–72 V DC) allows operation across various vehicle, industrial, and telecom power systems. Compliance with EN50155 and RoHS indicates suitability for railway-related applications and adherence to environmental restrictions. Its compact dimensions and enclosed design support secure mounting and protection against mechanical stress.
Suitable for (tasks / use cases)
Automotive and commercial vehicle 12 V subsystems
Railway and rolling stock power supplies compliant with EN50155
Industrial control equipment requiring isolated 12 V rails
Telecom and network devices in wide-voltage installations

Compliance: RoHS
How to use
Mount the enclosed converter in a location with adequate airflow and secure it using the recommended mounting points. Connect the DC input to a suitable 18–72 V source, observing correct polarity and ensuring the source can supply required startup and running currents. Connect the 12 V output to the load, respecting the maximum 2.5 A current rating. Ensure wiring and connectors are rated for the voltages and currents in the installation and provide proper fusing on the input side as required by local regulations or system design. Verify system grounding and isolation before applying power.
Usage recommendations
For reliable operation, avoid placing the converter near heat sources or in confined spaces with insufficient ventilation. Use short, well-sized wiring to minimize voltage drop at higher currents, and include input-side surge protection when used in vehicle or railway environments. Observe the device’s isolation rating when integrating it into systems with mixed voltage domains.
