Middle Atlantic PD-DC-125R DC Power Distribution Unit
Overview
The Middle Atlantic PD-DC-125R is a 125W rack-mount DC power distribution unit that consolidates multiple low-voltage device feeds — 5V, 12V, 18V, and 24V — into a single, rackmounted enclosure. If your rack currently has a tangle of individual wall wart adapters powering cameras, access control readers, or small network appliances, the PD-DC-125R replaces that mess with one unit, one AC connection at 120V, and clearly labeled outputs. It's sized for small-to-medium device loads where centralized, organized DC distribution matters more than high-wattage bulk output. The color-coded screw terminal connectors on the Middle Atlantic PD-DC-125R make field termination straightforward and reduce mis-wiring risk during initial commissioning or future changes.
Compatibility
Designed for small-to-medium DC-powered devices commonly found in security power distribution and AV rack builds. Appropriate device types include 12V fixed IP cameras, 24V access control panels and door strikes, 5V and 12V network appliances, and 18V or 24V intercoms. Compatible with standard 19-inch rack enclosures given its rack-mount form factor. Pairs naturally with network video recorders and associated peripheral devices that require regulated DC at multiple voltages. Also suited for wall-mount applications where a rack panel is used in an enclosure or surface-mount backbox. For larger deployments with higher aggregate wattage demands — multi-camera systems drawing 200W or more — consider a higher-capacity unit in the Middle Atlantic power distribution line before committing to this model.
Installation Notes
Input is AC 120V; verify your rack or enclosure circuit is a standard 15A or 20A branch. All load connections terminate via screw terminals — a flathead or Phillips screwdriver is required, no crimp connectors or proprietary tooling needed. Color-coded terminal blocks reduce the chance of cross-connecting voltage rails during wiring. Distribute load across the available voltage outputs to stay within the 125W aggregate capacity; exceeding total wattage across all outputs simultaneously risks thermal shutdown or tripped protection. Supports both rack-mount and wall-mount installation, making it usable in shallow-depth enclosures where a full rack rail isn't present.
