## Summary description

Extralink SD-50C-24 is a DC/DC voltage converter that accepts nominal 48V input and provides 24V output at up to 50W. Designed for universal power supply use, it features a metal housing, metallic finish and passive cooling for silent operation. Typical applications include powering 24V equipment from 48V systems in telecom, network or industrial setups.

## Long description

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.
Suitable for
 Powering 24 V telecommunication and network devices from 48 V power plants
 Supplying 24 V sensors, relays and control modules in industrial installations
 Use in central offices, remote sites or equipment cabinets where silent operation is required
Key specifications
 Input voltage: nominal 48 V DC
 Output voltage: 24 V DC, regulated
 Maximum output power: 50 W continuous
 Cooling method: passive (convection through metal housing)
 Enclosure: metal with metallic finish
 Typical applications: telecom, network and industrial power conversion
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.
Usage 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.
