Industrial 48 V single-output supply

The Mean Well HRP-300-48 converts 85 to 264 VAC at 47 to 63 Hz into a regulated 48 VDC rail rated at 7 A for 336 W maximum output. It is built for equipment that needs a steady 48 V source rather than a multi-rail PC-style unit.

Compact enclosed chassis with screw terminals

The proprietary form factor fits into machinery cabinets and rack trays where standard ATX dimensions are not required. Input and output connections use screw terminals, so wiring can be secured without specialised crimp tools and inspected visually during maintenance.

No bundled cables or configuration software

The unit ships as a standalone module; integrators supply their own input cord, output leads and any mounting hardware the enclosure demands. This keeps the bill of materials predictable for volume builds and avoids surplus cables in tight cabinets.
