Product gallery
The Zentronics OCP / V3 power shelf.
A 1U ORV3-mechanical shelf populated with front-serviceable rectifier cassettes, feeding the rack’s common bus-bar output.
Product overview
One shelf, engineered for the open rack.
Shelf capacity, rectifier count, redundancy scheme, output bus voltage and management interface are configured around the rack, load profile and operating team.
Key capabilities
- Open Rack V3 mechanical envelope with rear bus-bar interface
- Front hot-swap rectifier cassettes for live service
- Configurable N+1 and N+N redundancy modes
- Optional battery back-up (BBU) bay alongside rectifiers
- Rack Management Controller with PMBus / I²C telemetry
- Model-dependent input feed: three-phase AC, HVDC or 800 VDC

Technical architecture
Designed as part of the open-rack power chain.
OCP-native mechanical
Open Rack V3 form factor with rear bus-bar output coexists with standard OCP compute and storage sleds inside the same rack column.
Front-serviceable rectifiers
Hot-swap PSU cassettes are replaced from the cold aisle without shutting the shelf down, keeping the rack live during service events.
Fleet-manageable telemetry
The Rack Management Controller streams per-rectifier voltage, current, temperature and health via PMBus / I²C to facility DCIM tooling.
Applications
Where this platform fits.
Shelf configuration is aligned to the load profile, redundancy plan, rack layout, monitoring architecture and target market.
AI training clusters on open-rack platforms
Enterprise Open Rack V3 deployments
High-density compute and analytics rows
Integration, staging and validation labs
Rack power conversion
Conversion, supervision and distribution engineered as one subsystem.
Zentronics rack power systems combine conversion modules, control, bus structures, protection and output distribution in compact rack-ready assemblies.
Configurations can include hot-swappable power modules, centralized supervision, battery-aware operation and interfaces for platform telemetry. The architecture is adapted to the load, redundancy objective, service method, rack mechanics and upstream/downstream distribution.
For OCP and high-density compute environments, power shelves and sidecar systems form part of a larger DC path that includes busbar monitoring, rack tap-off, protection and intelligent distribution.
