Black Box SDR-240-48 – DIN Rail Industrial Power Supply 240W 48VDC

Product Overview

The Black Box SDR-240-48 is a 240-watt DIN rail-mount industrial power supply with a 48VDC output, designed for permanent installation in industrial control panels, AV equipment enclosures, and building automation systems. With a wide AC input range and a compact DIN rail form factor, this power supply is engineered for installations where reliable, continuous DC power delivery to field devices, network equipment, and AV infrastructure is required in demanding environments. It is well-suited for AV and control system integrators deploying powered infrastructure in manufacturing, transportation, utilities, and commercial facilities.

Product Description

The SDR-240-48 delivers 240 watts of regulated 48VDC output from a universal AC input (85–264VAC, 47–63Hz), making it compatible with standard single-phase AC power in North American, European, and international installations. The DIN rail mounting form factor integrates directly into standard IEC EN 60715 (35mm) DIN rail systems found in industrial control panels, network cabinets, and AV infrastructure enclosures used in transportation hubs, utility facilities, and commercial building automation. A 48VDC output is the standard voltage for PoE network switches, industrial Ethernet devices, IP intercoms, access control systems, and some high-wattage professional AV components. The unit features active PFC (Power Factor Correction) and protection circuits including over-voltage, over-current, short-circuit, and over-temperature protection, ensuring reliable operation in environments where power conditions may not be ideal. Convection cooling (fanless operation in many configurations) reduces audible noise, which is beneficial in AV equipment rooms adjacent to occupied spaces.
