Power architecture for AI infrastructure
One coordinated portfolio for busway tap-off, intelligent rack distribution, 800 VDC-to-48 VDC conversion and facility-level power monitoring.
Complete DC power chain
Zentronics brings the four essential 800 VDC building blocks together on one engineering platform.
The portfolio connects overhead distribution to the rack, protects and meters individual branches, converts high-voltage DC close to the compute load and exposes electrical performance to facility systems.
Each product is configured against the source architecture, fault level, rack load, cooling design, output interface, service procedure and required monitoring depth.
800 VDC product portfolio
Select individual building blocks or engineer them together as an integrated system.
Busway interface
Creates the protected transition from an overhead DC busway to the rack power path.
Rack distribution
Distributes the rack input across protected branches with electrical visibility and optional intelligent supervision.
Rack-side conversion
Converts facility-level 800 VDC to the 48 VDC bus required by high-density compute platforms.
Facility visibility
Measures the DC power path from facility distribution through rows, tap-offs and rack entry points.
Architecture sequence
Move power through the facility or row busway with lower conductor current than a comparable low-voltage DC architecture.
Use a project-matched tap-off to establish the protection, isolation and metering boundary at each rack.
Feed 800 VDC loads through an intelligent PDU or convert close to the rack through a 48 VDC sidecar platform.
Combine busbar, tap-off, rack and branch telemetry to understand capacity, balance, energy and operating state.
Capability matrix
| Product layer | Primary role | Engineering options | Typical interfaces |
|---|---|---|---|
| Rack Tap-off | Busway-to-rack protection and isolation | Busway interface, DC protection, pole isolation, local metering and output connection | Overhead busway to cable, busbar or keyed connector |
| Intelligent PDU | Rack-level branch distribution | Branch quantity, protection, switching, metering, alarms and environmental sensing | 800 VDC input to protected rack branches |
| Sidecar Converter | High-voltage to 48 VDC conversion | Power capacity, module count, redundancy, cooling, output bus and controller | 800 VDC input to 48 VDC compute bus |
| Busbar Monitoring | Facility and row electrical visibility | Measurement points, current range, accuracy, logging, alarms and communications | Sensors and meters to DCIM/BMS/network systems |
Final ratings and feature availability are project-specific. The approved system specification defines voltage range, current, protection, insulation, connectors, telemetry, compliance and environmental limits.
Safety and system engineering
Source behaviour, available fault energy, conductors, interruption devices, insulation, touch protection, polarity, earthing and service procedures are evaluated together.
Zentronics coordinates the product interfaces with the approved busway, rack mechanics, conversion architecture and facility operating method. Component selection and compliance scope are confirmed from the actual installation requirements.
DC-rated interruption and protection coordination
Insulation, clearance and controlled isolation
Keyed connectors, interlocks and alarm interfaces
Conductor sizing, thermal rise and cooling integration
Intelligent monitoring
Applicable controllers bring together local status, electrical measurements, alarms and remote management.
Measurement can be placed at the facility feed, busway, rack tap-off, PDU inlet, individual branch, converter input or 48 VDC output. This layered visibility supports commissioning, capacity planning, load balancing, fault investigation and lifecycle operation.
SNMP, Modbus TCP, Ethernet and serial options are available across supported configurations. Final protocol, cybersecurity, polling and data-retention requirements are defined per project.
Applications
Facility-to-rack DC architecture for GPU and accelerator systems with high power density and detailed telemetry.
Repeatable row and rack power building blocks designed around capacity, availability and service access.
Sidecar and power-shelf integration for platforms using a 48 VDC rack bus or modular conversion architecture.
Measurable, protected rack boundaries that support tenant capacity and future high-density deployment.
Instrumented distribution and conversion platforms for 800 VDC product development, commissioning and load testing.
Application-specific electrical, mechanical, firmware and communication variants developed from approved interface data.
In-house execution
Zentronics coordinates electrical architecture, protection, power electronics, metering, embedded control, mechanical integration, manufacturing and validation.
Share the facility source, busway, rack load, conversion, protection and monitoring requirements with Zentronics.
