Engineered power infrastructure for mission-critical systems

Rack power distribution

DC Power Distribution Units

Choose the right level of control for high-current DC rack and telecom power — from dependable basic distribution to local metering and fully connected intelligent PDUs.

Three product levels

Start with the visibility and control you need.

Every level is available in vertical and horizontal formats. Electrical ratings, outlets, protection and communication options are configured for the application.

Mechanical formats

Designed around the rack, not around a fixed enclosure.

Vertical PDUs

0U mounting preserves equipment space and supports higher outlet densities along the rack height. Ideal for cabinet rows and high-density deployments.

Horizontal PDUs

1U and 2U rack-mount formats provide accessible front or rear distribution for network, telecom, lab and compact rack installations.

DC PDU technology platform

High-current DC distribution with measurement, control and automation.

Zentronics DC PDUs are designed for telecom, data-centre, HPC, AI, laboratory and product-validation environments that require protected DC distribution with clear operational visibility.

The portfolio includes basic, metered and intelligent configurations in vertical and horizontal formats. Application-specific architectures can support -48 VDC systems, dual feeds, high-current busbars, individual branches and customer-selected connector or harness arrangements.

Applicable intelligent DC PDUs measure DC voltage, DC current and DC power. Cumulative energy and time-series measurements can be retained and exported as CSV data within supported configurations, giving operators and test teams a practical record for analysis and troubleshooting.

Linux-based control supports Ethernet and serial connectivity, including RS-232 or RS-485 according to the selected design. Dedicated environmental interfaces and USB expansion can connect temperature and humidity sensors, storage devices and application-specific peripherals, including USB cameras where the approved configuration supports them.

Supported interfaces allow C and Python applications to automate switching, collect telemetry, coordinate test sequences and integrate the PDU into continuous-validation environments.
