Power DB Boxes: Manufactures, Types, Features & Applications


Power distribution boxes, also known as power distribution units (PDUs), are devices that provide electrical power to various equipment and devices. They serve as a central location for distributing power to multiple devices from a single source. The distribution of power boxes is commonly used in industrial and commercial settings, such as data centers, factories, and offices.

Power distribution boxes come in various sizes and configurations to meet different power requirements. They typically consist of multiple outlets, circuit breakers, and other electrical components that help distribute power to various devices. Some power distribution boxes also come with monitoring and control features that allow users to monitor power usage and adjust power distribution as needed.

One common type of power distribution box is the portable power distribution box, which is designed for temporary use in construction sites, outdoor events, and other similar settings. Portable power distribution boxes are often mounted on carts or frames and come with features such as weather-resistant casings and heavy-duty cables.

Another type of power distribution box is the rack-mount power distribution unit (PDU), which is designed for use in server racks and data centers. These PDUs are typically mounted in the rear of the rack and feature multiple outlets and power monitoring and control features.

In addition to these common types, there are also custom power distribution boxes that can be designed to meet specific power requirements and configurations. These customized enclosures may include features such as remote monitoring and control, surge protection, and ground fault protection.

Also, the connection of power distribution boxes to power conditioners and sequencers is an important part of a larger power conditioning system and can help to ensure that electrical power is distributed safely and efficiently to sensitive equipment.

History of Power DB Boxes

Power distribution boxes (DB boxes) have been used for decades to distribute and control electrical power in various settings. The history of these boxes can be traced back to the early 20th century when electrical power was first adopted for use in homes and businesses.


In the early days of electrical power, homes, and businesses were typically powered by a single circuit that supplied power to all devices and appliances. As the demand for electrical power grew, it became necessary to distribute power more efficiently, and the concept of a power distribution box was born.


The first power distribution boxes were simple devices that contained fuses or circuit breakers that could be used to control the flow of electricity to different parts of a building. These early boxes were typically made of metal and were mounted on walls or in cabinets.


Over time, the design of power distribution boxes evolved to include more advanced features and greater capacity. In the mid-20th century, power distribution boxes began to incorporate switches, meters, and other control devices that allowed for greater control and monitoring of electrical power.


With the advent of computers and other electronic devices in the latter half of the 20th century, power distribution boxes became even more important, as they were used to control the flow of power to sensitive electronic equipment. Today, power distribution boxes are used in a wide variety of settings, from residential homes and small businesses to large industrial complexes and data centers.


Advances in technology have resulted in the development of smart power distribution boxes that can be controlled remotely and provide real-time monitoring of electrical usage in recent years. These boxes are intended to improve energy efficiency and lower costs by allowing users to monitor and adjust their power consumption using real-time data.

Classifications of Power DB Boxes

Power distribution boxes (PDBs) are classified based on their intended application and their electrical specifications. Here are some common classifications of power DB Boxes:


  1. Portable Power Distribution Boxes: These PDBs are designed to be easily moved from one location to another and are commonly used on film sets, outdoor events, and construction sites. They are compact and rugged, built to withstand harsh conditions.
  2. Wall-mounted Power Distribution Boxes: These PDBs are typically installed in permanent locations, such as buildings or factories. They are designed to distribute power to multiple circuits in a central location, making them ideal for large commercial and industrial applications.
  3. Rack-mount Power Distribution Boxes: These PDBs are designed to be installed in equipment racks, such as those used in data centers or broadcast facilities. They are typically smaller in size than wall-mounted PDBs and are used to distribute power to servers, network switches, and other rack-mounted equipment.
  4. Outdoor Power Distribution Boxes: These PDBs are designed to be installed in outdoor locations, such as parking lots or construction sites. They are weather-resistant and rugged, built to withstand exposure to the elements.
  5. Explosion-proof Power Distribution Boxes: These PDBs are designed for use in hazardous environments where there is a risk of explosion, such as oil refineries, chemical plants, and mines. They are designed to contain any explosions that may occur and prevent them from spreading to other areas.
  6. Low-voltage Power Distribution Boxes: These PDBs are designed to distribute low-voltage power to various circuits. They are commonly used in homes and small businesses, where the power demand is relatively low.
  7. High-voltage Power Distribution Boxes: These PDBs are designed to distribute high-voltage power to various circuits. They are commonly used in industrial applications, such as factories and power plants.


In summary, power distribution boxes are classified based on their intended application and electrical specifications. Some of the most common classifications include portable, wall-mounted, rack-mounted, outdoor, explosion-proof, low-voltage, and high-voltage power distribution boxes.
