Description
RO Associates DB48-24S-2 Attachment Plate w/ 2x uV48-24 DC-DC Converter 24VDC
The RO Associates DB48-24S-2 is a dual DC-to-DC converter attachment plate, combining a carrier PCB with two factory-mounted uV48-24 converter modules. Each uV48-24 module accepts a 48V DC input and delivers a regulated 24VDC output at up to 10A. The assembly integrates both modules onto a single board with a shared wiring harness, simplifying installation in systems requiring a stepped-down 24V supply from a 48V bus.

Applications
DC-to-DC converter assemblies like the uV48-24 are used in telecom and datacom equipment racks, industrial control systems, and embedded power architectures where a 48V distribution bus (standard in telecom infrastructure) must be stepped down to 24V for downstream loads such as control boards, sensors, or lower-voltage subsystems. The 48V telecom bus standard became widespread in central office and carrier equipment from the 1980s onward, and 48V-to-24V converters of this type remain in use for maintaining and retrofitting that infrastructure. The dual-module attachment plate format allows two converter channels to be managed and mounted as a single field-replaceable unit, which is practical in high-availability or space-constrained installations.
This RO Associates DB48-24S-2 DC-to-DC Converter Attachment Plate has been inspected and appears to be in good used condition. It was pulled from a working environment where it was previously in service. Both uV48-24 converter modules are installed and the wiring harness with ring and spade terminals is attached. The PCB, heatsinks, and components show normal wear consistent with prior use, with no visible damage. Please view our photo set and contact us if you have any questions.
