What type of units may have multiple panelboards within a single cabinet for information technology equipment?

Power distribution units (PDUs) are specifically designed to manage and distribute electrical power to various equipment, particularly in data centers, telecommunications facilities, and other environments where information technology equipment is used. PDUs can be configured to house multiple panelboards within a single cabinet, allowing for efficient distribution of power to different devices while maintaining a compact footprint.

This configuration helps in organizing the power management for IT equipment, as PDUs can offer various outlets and circuits to connect different devices. They may also include features such as monitoring capabilities, surge protection, and remote management features, making them a critical component in optimizing power distribution in data environments.

While power management systems and uninterruptible power supplies play vital roles in power quality and continuity, they typically do not house multiple panelboards as part of their primary function. Service disconnects are used primarily for safety and isolation of electrical supply and are not structured to offer the same distribution capabilities as PDUs.
