Description

Black Box MDR-40-48 Low-profile Power Supply

Overview

The Black Box MDR-40-48 is a compact, low-profile 48V DC power supply designed for installations where space is at a premium. Its small footprint allows for discreet integration into tight enclosures, junction boxes, or behind equipment, making it suitable for deploying surveillance cameras or other low-voltage devices without compromising aesthetics or requiring extensive cabinet space. This unit provides stable power output for reliable operation.

Compatibility

This power supply is designed to output 48V DC, making it compatible with a wide range of low-voltage devices that accept this input, including many IP cameras, network switches, and other surveillance system components requiring a stable DC power source. It is particularly useful for powering devices that do not support Power over Ethernet (PoE) or require a dedicated power source.

Installation Notes

The MDR-40-48 requires direct wiring for both input and output connections. Ensure that the input voltage (typically AC mains) is within the specified range for the unit. The output is a regulated 48V DC, suitable for devices with appropriate power input specifications. Due to its low-profile design, it can be mounted in confined areas, but adequate ventilation should be maintained to prevent overheating. Verify that the total power draw of connected devices does not exceed the supply's capacity.
