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

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

Overview

The Middle Atlantic PD-DC-300-24V is a purpose-built DC power distribution unit that consolidates 24-device power into a single, rack-managed unit — eliminating the rats' nest of individual wall warts that plague camera and access control deployments. At 300W total capacity with a fixed 24V DC output, it converts standard AC mains (120–240V universal input via IEC 60320 C14) into clean, distributed DC power across 24 screw-terminal outputs, each tapping from the 12.5A total output current budget. For integrators wiring surveillance or access control panels in an IDF closet or security rack, this unit is a hard-to-skip consolidation play.

The PD-DC-300-24V (often searched as PD DC 300 24V) ships in a 1RU or Zero-U form factor, giving you two placement options depending on rack availability — mount it in a standard 19-inch rack or tuck it vertically in a Zero-U position to keep rack units free for active gear.

Key Features

• 300W Total DC Capacity: With 300 watts available across the unit, you can distribute power to a mix of 24V cameras, readers, or control devices without the overhead of per-device power supplies. Size your load per-port carefully — 300W across 24 ports averages 12.5W per output, but real-world current draw varies by device.
• 24V DC Fixed Output: Delivers a stable 24V DC rail to all 24 outputs — the correct voltage for a wide range of commercial IP cameras, door controllers, and access readers that specify 24V DC rather than PoE. No tap-selection, no miswiring: voltage is fixed at the factory.
• 12.5A Total Output Current: The full 12.5A output budget is shared across all 24 screw terminals. Map your device current draws before commissioning — a mix of 24V cameras (typically 0.3–0.6A each) leaves headroom for a full 24-device load, but high-draw PTZ cameras or heaters on the same unit can tighten the budget fast.
• 24x Screw Terminal Outputs: Screw terminals are field-serviceable and don't require proprietary connectors — you can add, swap, or troubleshoot individual runs without special tooling. This is the right interface for permanent wiring runs in a finished security cabinet, where barrel-connector wall warts would be a liability.
• Universal AC Input (120–240V) via IEC C14: The IEC 60320 C14 inlet accepts standard C13 power cords and works on both 120V (North American) and 240V (international or high-leg delta) circuits. For multi-site integrators deploying standard rack kits, this removes the voltage-selection step entirely.
• 1RU or Zero-U Rack Mounting: Two mount configurations give you flexibility at the rack planning stage. Install in a 1RU slot in a standard open-frame or enclosed rack, or use Zero-U mounting to keep rack unit count free for network gear, NVRs, or patch panels. At 7.26 inches deep, verify clearance against the rear of shallow-depth enclosures before ordering.
• Wall and Rack Mount Options: Beyond the rack, the unit supports wall mounting — useful in smaller IDF closets or remote camera head-end locations where a full rack isn't justified but centralized power distribution still is.

Integration & Compatibility

The PD-DC-300-24V fits naturally into any DC power distribution strategy where 24V DC devices dominate the load. It pairs well with Middle Atlantic rack enclosures and open-frame racks, but the IEC C14 inlet and standard screw terminals make it compatible with third-party rack ecosystems. If your NVR or access control panel specifies 24V DC input, this unit can feed it directly — confirm the device's max current draw against the 12.5A shared budget. For camera deployments mixing PoE and 24V devices, use a dedicated PoE switch for the PoE cameras and this unit for the 24V devices — don't try to run both on a single supply.

Frequently Asked Questions

Q: What is the total power output of the PD-DC-300-24V?

A: The PD-DC-300-24V delivers 300W total at 24V DC with 12.5A total output current, distributed across 24 screw-terminal outputs.

Q: Can the PD-DC-300-24V be wall-mounted instead of rack-mounted?

A: Yes. The PD-DC-300-24V supports both rack mounting (1RU or Zero-U) and wall mounting, making it flexible for locations where a full rack isn't available.

Q: What type of input connector does the PD-DC-300-24V use?

A: It uses a standard IEC 60320 C14 inlet, compatible with common C13 power cords and universal 120–240V AC mains.

Q: How deep is the PD-DC-300-24V — will it fit in a shallow rack enclosure?

A: The unit is 7.26 inches deep. Measure your enclosure's usable depth (from the rail face to the rear panel, accounting for cable management) before installing in shallow enclosures.

Q: How many devices can the PD-DC-300-24V power simultaneously?

A: It provides 24 individual screw-terminal outputs. The total current budget is 12.5A at 24V DC (300W), so the number of devices depends on each device's current draw — verify the combined load stays within 12.5A total.

Q: Is the output voltage adjustable on the PD-DC-300-24V?

A: No. The PD-DC-300-24V provides a fixed 24V DC output. It is not a variable-voltage unit — confirm all connected devices specify 24V DC input before wiring.

Karl Wilson

When I'm spec'ing power for a 24V DC camera or access control installation, the PD-DC-300-24V is the unit I reach for when the device count justifies centralization. The 12.5A total output current at 24V is the number that runs the design — that's your hard ceiling across all 24 screw terminals, and it comes before any derating for ambient heat in a loaded rack enclosure.

Technical Highlights:

• 300W / 12.5A Budget: At 300W across 24 ports, you're averaging ~12.5W or ~0.52A per port at 24V. A typical 24V fixed-lens IP camera draws 0.3–0.5A — so a fully loaded camera deployment fits comfortably, but mix in any PTZ with a heater and your per-port math shifts fast.
• Universal AC Input (120–240V, IEC C14): The C14 inlet means any standard C13 line cord works, and the 120–240V range removes the need to specify a different unit for international sites or facilities on 208V. One SKU covers the breadth of typical commercial deployments.
• 1RU + Zero-U Dual Mount: The ability to mount Zero-U is underrated — on a fully loaded NVR rack, preserving rack units for active compute is real. The 7.26-inch depth is the spec to verify against your enclosure; most 15–17 inch deep wall enclosures accommodate it, but measure first.

Deployment Considerations:

• Load balance before wiring: if you have a mix of high- and low-draw devices, document the per-port current draw and sum to confirm you're staying under 12.5A total. A current clamp on the AC input after commissioning is a quick sanity check.
• The fixed 24V output is a hard constraint — this unit cannot power 12V devices. If your deployment mixes 12V and 24V cameras (common in retrofit scenarios), you'll need a separate supply for the 12V load or a multi-voltage distribution unit.

This unit is the right call for a physical security head-end — particularly an IDF closet feeding a bank of 24V access control readers and fixed cameras on a common Middle Atlantic rack infrastructure, where eliminating 24 individual wall warts is worth the rack real estate at 1RU.
