There are several types of Power Distribution Units (PDUs) available to meet different power distribution and management needs in various environments. The exact number of PDU types can vary depending on how you categorize them, but here are the main types commonly encountered:

 

  1. Basic PDUs: These provide straightforward power distribution without remote monitoring or control capabilities. They typically consist of power outlets and may include basic surge protection or circuit breakers.

 

  1. Metered PDUs: Metered PDUs offer power monitoring at the outlet or circuit level, providing real-time data on current, voltage, power factor, and energy consumption.

 

  1. Switched PDUs: Switched PDUs combine power distribution with remote outlet-level control, allowing administrators to turn individual outlets on or off remotely. They provide basic control features.

 

  1. Monitored and Switched PDUs: These PDUs offer both monitoring capabilities (similar to metered PDUs) and remote outlet-level control (similar to switched PDUs).

 

  1. Smart PDUs: Smart or intelligent PDUs provide advanced monitoring, control, and management features. They typically offer outlet-level monitoring, remote control, environmental sensors (e.g., temperature, humidity), alarms, and reporting capabilities.

 

  1. Managed PDUs: Managed PDUs combine the features of smart PDUs with network management capabilities. They can be integrated into network management systems and support protocols like SNMP. Managed PDUs offer extensive control and monitoring over power distribution and can be centrally managed through a network interface.

 

  1. Switched, Metered, and Monitored PDUs: These PDUs combine multiple features, offering remote control (switching), outlet-level monitoring (metering), and overall power consumption monitoring (monitoring).

 

  1. Rack-Mount PDUs: Most PDUs are designed for rack-mounted installations, making them suitable for data center racks and server cabinets. They come in various form factors, including vertical (0U) and horizontal (1U, 2U, etc.) options.

 

  1. Vertical PDUs: Vertical PDUs are designed to be mounted on the sides of server cabinets or enclosures. They provide power distribution for equipment inside the cabinet and save valuable rack space.

 

  1. Horizontal PDUs: Horizontal PDUs are rack-mounted PDUs that are installed horizontally within the server rack, typically taking up one or more rack units (U) of space. They are commonly used for distributing power to equipment within the rack.

 

  1. In-Line PDUs: In-line PDUs are designed to be placed between the main power source (e.g., wall outlet) and the equipment. They can provide power monitoring and surge protection and are often used in non-rack-mounted or specialized applications.

 

The specific type of PDU chosen depends on the power distribution needs, monitoring and management requirements, environmental conditions, and budget considerations of the data center or facility where it will be deployed. Organizations can select the PDU type that best aligns with their goals and operational needs.
