Power Distribution Unit (PDU)

Buy Power Distribution Unit (PDU) Hardware for Rack Management

When you need to buy power distribution unit hardware, you are looking for more than a simple power strip. Dense Server Rack requires space-saving physical formats, high amperage, and organization. BulkDevices provides powering solutions for vertical (0U) and horizontal (1U) units that provide clean and monitored power to each device. All of our power distribution units for sale are engineered to run continuously, ensuring you never have to deal with loose cables, overloaded circuits, or unplanned downtime. The entire power chain in the data center is reliable from the start of the power chain.

From Basic Strips to Enterprise PDU Solutions

Basic power distribution simply takes one input and splits it across multiple outlets. That works for small network closets, but it offers zero visibility into actual power draw. To truly protect infrastructure, you need an enterprise PDU that provides real-time metering and network connectivity. An enterprise-grade unit allows administrators to see exactly how many amps each server draws, set per-phase thresholds, and receive alerts before a breaker trips. This proactive approach prevents sudden outages during peak loads. This is a key component of our Power Classification catalog for data centers, bridging basic strips and fully managed infrastructure.

Selecting a Rack Mount PDU and Intelligent Features

When your team moves from basic power to remote management, it's a change of daily operations. A rack mount PDU with built-in intelligence will save hours of on-site time and lower mean time to repair. The right intelligent PDU is in your hands while in the cabinet. The following are three control levels you'll want to consider when it comes to business power distribution:

  • Metered PDU: A local LED screen shows total amp draw per phase or bank, and lets the installer balance loads manually without needing access to the network, a perfect feature for colocation cages where there is limited remote management.
  • Switched PDU: The PDU capability of toggling individual outlets by entering their IP address into a web browser, allowing instant hard reboot of a hung server without sending out a tech to do so.
  • Form Factor (0U/1U): A vertical rack mount PDU (0U) mounts on the back side channels, taking up no width, and a horizontal (1U) can be installed directly above or below patch panels.
The best density and remote control balance is obtained by a switched or metered PDU in combination with 0U mounting for most production racks. Select depending on your requirement for switching per outlet or if you just need local load monitoring.

Top Brands: APC, Eaton, Schneider, CyberPower, and Tripp Lite

The type of manufacturer you choose will significantly influence software integration, longevity, and support. In the case of mission-critical floors, the APC pdu series and Schneider Electric pdu line are deemed data center standards. These include powerful network management cards, smooth integration with the DCIM software, and granular per-outlet switching. The Eaton PDU lineup is ideal for industrial applications for environmental probes. Eaton units provide high precision power measurement, and are optionally available with temperature and humidity sensors for full rack monitoring. On the other hand, if the server closet is smaller and/or budget is a concern, CyberPower PDU and Tripp Lite PDU are both very good values. These brands offer the basic and metered options at affordable prices and are dependable in terms of safety and performance.

Input and Output Types (C13, C19, L6-30)

Residential power strips use NEMA 5-15 plugs, but data center PDUs require locking connectors to prevent accidental disconnection. Most server power supplies accept C13 outlets (10A rating), while high-performance blade chassis and network switches need C19 outlets (16A rating). On the input side, you will typically find a twist-lock L6-30P plug for 208V or 240V high-voltage circuits. Always verify your rack’s receptacle type and voltage before purchasing. Matching plug and outlet ratings prevents overheating, ensures electrical code compliance, and avoids costly returns.

Frequently Asked Questions(FAQs)

What is a “Switched” PDU?
A switched PDU allows you to control power to each outlet remotely via web interface or SNMP. This is critical for performing a hard reboot on a frozen server from your desk instead of driving to the data center.

Can I daisy-chain PDUs?
For power, NO. Never plug one PDU into another—this creates a fire hazard and violates safety codes. For management data, YES. Many intelligent PDUs allow you to link up to 32 units via Ethernet to manage them all from one IP address.

What is “0U” mounting?
Zero-U refers to mounting the PDU vertically in the back of the server rack cabinet. It consumes “Zero Units” of horizontal rack space, leaving more room for servers, switches, and patch panels.
