With simple 0U and 1U installation options, HPE Basic Power Distribution Units are available in multiple form factors allowing you to configure access to power in your rack where you need it the most. HPE Basic PDUs provide a low-profile single-piece design allowing easy access to rear devices for maintenance. Vertical PDUs can be installed on either side of the rack with outlets facing the back of the rack for easy access and improved clearance. For higher power density configurations, they can be installed side by side on both sides of the rack with the outlets facing towards the center. Horizontal/Modular PDUs offer a modular architecture designed for data center customers who want to maximize power distribution and space efficiencies. The Control Unit or core can be mounted in any 1U space or in 0U space on the side of HPE Racks between the RETMA rails. Extension Bars mount directly to the frame so you can configure access to power where you need it.
