DC/DC Voltage Converter Extralink SD-50C-24 48V→24V 50W Passive-cooled Metal Case

Extralink SD-50C-24 is a DC/DC voltage converter that accepts a nominal 48 V input and delivers a stabilized 24 V output with up to 50 W of continuous power. Housed in a metal enclosure with a metallic finish and designed for passive cooling, this converter provides silent, maintenance-free operation for use in telecom, network and industrial power systems where 24 V loads must be supplied from 48 V sources.

Advantages

The metal case offers mechanical robustness and improved heat dissipation while passive cooling eliminates moving parts and audible noise. The converter is built for universal mounting and electrical compatibility with common 48 V power systems, delivering a reliable 24 V rail at up to 50 W. Compact dimensions and a simple connection layout make it suitable for integration into racks, cabinets or small enclosures.

How to use

Install the converter in a location with adequate ventilation and secure it using appropriate mounting hardware for the metal enclosure. Connect the 48 V DC supply to the input terminals observing correct polarity, then connect the 24 V DC load to the output terminals. Verify connections and voltage levels before applying full load. Allow the unit to operate without obstructing airflow around the housing to maintain passive cooling efficiency.

Recommendations

For reliable operation, avoid exposing the unit to excessive ambient temperatures or direct moisture. Use appropriate fusing on the input and output circuits to protect against faults, and confirm that connected loads do not exceed the 50 W continuous rating. Periodic inspection of terminals for secure connections is advised in installations subject to vibration.
