What Is a Power Distribution Rack?

A stroomverdelingsrek is a rack-mounted system that houses one or more power distribution units (PDUs), breakers and outlet panels, centralizing the delivery of mains power to multiple devices. In practice, this setup provides “space-saving power distribution in a flexible design”. For example, a PDU is defined as “a device fitted with multiple outputs designed to distribute electric power”, and mounting these PDUs in a standard 19-inch frame keeps servers, lighting consoles, audio gear and other equipment neat and accessible. In effect, the rack becomes the last-mile power hub – taking high-current feeds (from generators or mains) and distributing them safely to lighting fixtures, amplifiers, servers, or other gear.

Belangrijkste onderdelen en functies

Power distribution racks include several key elements and optional features to suit demanding applications:

• Standard Rack Sizes: Nearly all power racks conform to the 19-inch equipment rack standard. A typical rack cabinet is 42U tall, but shorter rack units (1U, 2U, 3U, etc.) are used for modular panels. This standard sizing ensures compatibility with existing racks and cases.

• Modular Construction: Many PDR designs allow custom modules or panels to be mixed-and-matched. For instance, Lex Products’ “PowerRACK” system lets users add receptacles to 19-inch racks and offers flexible input/output options for audio, lighting and other equipment. In practice, you can choose different inlet modules (e.g. Cam-Lok, powerCON, L21-30, etc.) and outlet panels (Edison, stage-pin, NEMA, etc.) to build the exact configuration needed.

• Input/Output Flexibility: Distribution racks typically handle high-current inputs and many output circuits. They may include Cam-Lok or stage-pin inlets (often rated 60A–400A) and multiple outlets or circuits on the output side. Many units support feed-through, ground-fault (RCD/GFCI) protection, and relay-controlled circuits. (For example, modular touring racks often allow “feed-thru” outlets so power can pass onward to the next rack.) This flexibility makes it easy to adapt the rack to event power management needs, whether powering lighting trusses, PA amplifiers, camera equipment or server cabinets.

• Veiligheidsvoorzieningen: Safety is paramount. Distribution racks usually incorporate circuit breakers (main and branch) sized for full load. High-end racks use 100%-rated electronic main breakers and magnetic branch breakers, eliminating the risk of nuisance tripping. Lock-out handles or remote emergency power-off (EPO) switches can instantly cut power if needed. Panels are often made of insulating materials (e.g. HDPE) and feature grounded enclosures for shock protection. Bright laser-engraved labels identify circuit numbers and load ratings for quick, error-free setup.

Applications and Use Cases

Power distribution racks are used wherever large or complex power needs must be managed in a controlled way. Typical applications include:

• Concerts, Theatrical and Live Events: A rolling power distribution rack is almost indispensable on tour. For example, Lex Products advertises that its rack PDUs are intended for “Concerts, Live Events, Motion Picture and Television Production”. Motion Labs similarly notes its 1–7RU rack PDUs serve “live event productions” and installation sites. In practice, stage crews use these racks to feed lighting dimmers, PA amplifiers, video walls and stage pin fixtures. Lex even calls its “PowerRACK” rolling units ideal for “touring applications where power requirements change frequently, like stage and studio applications”. Such racks simplify event power management by centralizing all feeds and breakers in one wheeled or fixed cabinet, greatly speeding setup and troubleshooting.

• Exhibitions and Trade Shows: At large exhibitions or corporate events, custom power racks feed booths and displays. They can provide dedicated breakers and monitoring for each vendor space, and often sit hidden in AV closets. These scenarios demand reliable distribution of single- and three-phase power to lighting, signage, demo stations, etc., so a pre-wired rack with clearly labeled circuits is ideal.

• Film and Broadcast Production: On-location shoots and studios often use portable rack power racks to distribute on-site generator power to cameras, lights and grip equipment. These racks handle heavy loads (e.g. 120/240V TVC lighting dimmers) and must be UL/CE-rated for safety. The modular nature means crews can configure panels for DMX, twist-lock, Cam-Lok or stage-pin as needed.

• Industrial and Commercial Sites: In factories, data centers, or workshops, similar concepts apply. For industrial power distribution, large cabinet-based PDRs or remote power panels (RPPs) distribute three-phase feeds to multiple machines or racks. A power rack in a control room might split a 400A feed into many sub-circuits (like distribution boards do). Heavy-duty rack frames and high-capacity busbars support factory automation systems, welding rigs, or computer server clusters.

CE Certification and Custom Solutions

Our company specializes in CE-certified, rack-mounted power distribution racks, offered in both standard catalog models and fully custom configurations. CE certification means each rack is tested to meet EU directives (low voltage, EMC, etc.), so customers can deploy them overseas without legal issues. We also build custom racks to match unique specs – for example, a rack with special connector types, mixed voltage outputs, or higher IP/ruggedness. Whether it’s a 2RU stage-panel or a fully enclosed 12U rolling distro, each rack can be tailored in enclosure color, labeling, and circuit layout.

Key highlights of our racks include: modular swap-in panels (a true stroomverdeler voor rekmontage approach), robust aluminum frames with shock-resistant panels, and options like built-in metering or remote switching. Safety devices (EPO, RCDs, surge protectors) are integrated as needed. In short, our solutions cover industriële stroomdistributie and entertainment rigs alike. We keep a selection of standard rack models in stock for quick delivery, and we excel at bulk and wholesale orders for large projects.
