Middle Atlantic DC PWR Dist 300W 12V 24V - PD-DC-300-12-24V

Middle Atlantic PD-DC-300-12-24V DC Power Distribution Unit

The Middle Atlantic PD-DC-300-12-24V is a 300W rack-mount DC power distribution unit designed to consolidate and clean up low-voltage power delivery for access control, security cameras, and other DC-powered field devices. If your rack or enclosure is currently crowded with individual wall warts and brick adapters, this unit consolidates that mess into a single managed source — one AC input, organized DC outputs at both 12V and 24V.

Key Features

• Split-Bank 12V and 24V Outputs: The unit runs two independent voltage rails simultaneously — 12V at up to 12.5A and 24V at up to 6.25A. That covers the two most common DC voltages in security and access control installations without requiring separate supplies for each device class.
• 300W Total Capacity: At full load across both banks, the PD-DC-300-12-24V handles a meaningful device count — enough for a dense IDF closet or mid-sized NVR rack with attached cameras and readers.
• Color-Coded Outputs: Outputs are color-coded by voltage rail, which speeds up wiring verification and reduces mis-connection risk during initial install and future adds or moves. In a dark IDF closet, color coding is a practical time-saver.
• Eliminates Wall Warts: Consolidating individual adapters into a single rack-mount unit reduces heat load, frees up AC receptacles, and removes a common point of unmanaged failure from the installation. A single unit is also easier to replace or audit during maintenance.
• Rack-Mount Form Factor: Designed for rack or wall mounting, the PD-DC-300-12-24V integrates into standard equipment enclosures alongside NVRs, switches, and other rack gear — keeping the power infrastructure in the same physical footprint as the equipment it serves.
• 6 ft Cord Length: The 6-foot AC input cord provides enough slack to reach a PDU or UPS on the same rack without extensions, which keeps the installation tidy and within reach of standard rack power strips.
• DC Series Platform: Part of Middle Atlantic's DC Series power distribution line, meaning replacement parts, mounting accessories, and compatible enclosures share a common ecosystem — useful for multi-site deployments where standardization matters.

Integration and Compatibility

The PD-DC-300-12-24V fits into rack enclosures and wall-mount brackets common to structured cabling and security installations. The dual-voltage split-bank design suits mixed device environments — for example, 12V IP cameras paired with 24V access control panels or electric strikes. For installations running centralized power distribution, this unit replaces multiple discrete adapters with a single managed source. Verify total connected load against the 12.5A (12V) and 6.25A (24V) per-bank limits before deployment — exceeding either bank rating independently will trip the unit even if total wattage appears within range.

Frequently Asked Questions

Q: Can the PD-DC-300-12-24V supply both 12V and 24V devices at the same time?

A: Yes. The split-bank design runs both voltage rails simultaneously — 12V at up to 12.5A and 24V at up to 6.25A — so you can power mixed device types from a single unit without separate supplies.

Q: What is the total wattage capacity of the PD-DC-300-12-24V?

A: 300W total across both banks. The 12V bank handles up to 12.5A (150W) and the 24V bank up to 6.25A (150W). Each bank is independently rated, so stay within each rail's amperage limit regardless of total wattage.

Q: Can the PD-DC-300-12-24V be wall-mounted as well as rack-mounted?

A: Yes. The unit supports both rack-mount and wall-mount configurations, giving flexibility for installations where a full rack enclosure is not present.

Q: How long is the AC input power cord on the PD-DC-300-12-24V?

A: The included AC cord is 6 feet, providing enough reach for standard rack power strips or UPS units in the same enclosure.

Q: What types of devices is the PD-DC-300-12-24V best suited for?

A: It is designed for DC-powered security and access control devices — including 12V IP cameras and 24V access control panels or electric strikes — in rack or wall-mount installations where consolidated power distribution is preferred over individual wall adapters.

Karl Wilson

The PD-DC-300-12-24V addresses something that trips up a lot of integrators on mixed-voltage jobs: you have 12V cameras on one side of the rack and 24V access control hardware on the other, and the temptation is to use whatever wall warts are handy. This unit replaces that approach with a single 300W source that delivers both rails cleanly — 12.5A on the 12V side and 6.25A on the 24V side — from one rack unit.

Technical Highlights:

• Split-Bank 150W Per Rail: Each bank is independently rated at 150W, so a spike or overload on the 24V access control side does not drag down the 12V camera rail — meaningful in installations where lock releases and cameras share the same enclosure.
• Color-Coded Outputs: In a dense rack with 20+ field device connections, color-coded outputs reduce mis-wiring and speed up troubleshooting during maintenance windows — a small detail that pays off on the second visit.
• 6 ft AC Cord: Long enough to reach a UPS on the same rack without an extension cord, which keeps the installation clean and avoids the added failure point of a daisy-chained adapter.

Deployment Considerations:

• Each voltage bank has its own amperage ceiling — 12.5A at 12V and 6.25A at 24V — so budget device loads per rail, not just against the 300W total. A 24V panel drawing 7A will exceed the 24V bank even if total wattage looks fine.
• Wall-mount is supported, but confirm the installation surface and conduit routing before committing — rack-mount in a structured enclosure is the cleaner long-term choice for serviceability.

This unit is a practical fit for mid-sized physical security deployments — a 16- to 32-camera system with a co-located access control panel — where the alternative is a shelf full of individual adapters that no one can identify two years after install.
