Rack PDU for Data Center Racks (K-SPM Series)
90KW Capacity — High-Density Intelligent Rack Power Distribution for Data Center Racks.
Conluxs K-SPM Series · Modular Architecture · Intelligent Management
Product Overview
The Conluxs K-SPM Series is an intelligent rack PDU — a rack power distribution unit engineered for high-density data center rack power delivery. Positioned at the end of the data center power chain, it receives power from upstream distribution and UPS feeder systems and distributes it to the IT loads inside a standard 19-inch server rack, with configurable outlet and branch protection.
Built on a modular architecture with a robust base frame and field-replaceable hot-swappable modules, the K-SPM is a monitored PDU that combines 90KW single-unit capacity with DSP-based precision metering and control. Real-time electrical parameters are available over SNMP/RS-485 connectivity for remote monitoring and facility integration, supporting maximum uptime for SME and banking branch micro-data centers, network and telecommunications infrastructure, and critical facility power.

- DSP Digital Control: High-speed processing for precision metering and control.
- 19-inch Rack-Mount: Standard form factor for seamless data center integration.
- Comprehensive Monitoring: Real-time electrical parameter tracking with SNMP/RS-485 connectivity.
- Multi-Channel Alarm System: Audible/visual alerts plus SMS and Email notifications.
Rack PDU Types and Configuration
Rack PDUs are commonly classified by their level of intelligence. A basic rack PDU only distributes power; a metered PDU adds local load readings; a monitored PDU exposes electrical parameters remotely; and an intelligent PDU adds management functions such as alarm escalation and facility integration. Choosing the right rack PDU configuration depends on the rack load, the input and output arrangement, the level of monitoring required, and the mechanical space available in the server rack.
The K-SPM Series is engineered as an intelligent, monitored rack PDU: DSP digital control delivers precision metering and fast response, a 7-inch LCD interface supports on-site operation and troubleshooting, and SNMP/RS-485 connectivity brings electrical parameters into the facility monitoring system for remote monitoring and alarm notification via SMS and Email. Individual configurations — capacity, input and outlet arrangements, branch protection and monitoring level — are specified per project to match the deployed rack power profile.
Where a Rack PDU Fits in Data Center Power Architecture
In a typical data center power chain, utility power flows through a UPS and then through distribution assemblies before reaching the IT space. UPS feeder cabinets condition and distribute UPS output toward the IT rooms, while data center precision distribution cabinets manage the final facility-side distribution downstream of the UPS. Between the feeder layer and the rack row, remote power panels (RPP) provide monitored row-level distribution with breaker-level visibility. At the rack level, the rack PDU is the last link in the chain: it takes the incoming feed and distributes it to the servers, storage and network equipment inside the rack, while monitoring the electrical parameters of that rack power load.
Between the distribution cabinets and the rack, project teams also decide whether to route power with traditional cabling or with busway vs cable distribution overhead. The choice affects scalability, routing flexibility and maintenance access, and should be made together with the rack PDU input configuration so the rack power architecture remains consistent from UPS feeder to server rack.
Engineering Advantages
| Advantage | Description |
|---|---|
| Flexible Deployment | Modular design fits standard 19-inch server racks, supporting both individual rack-level and row-level distribution management. |
| 7" LCD Interface | High-definition, feature-rich display ensures aesthetic integration and simplifies operator rounds and troubleshooting. |

| Proactive Safety Management | Full integration into facility monitoring systems allows real-time detection of circuit breaker status, load ratios, and harmonics, identifying latent hazards before they escalate. |
Frequently Asked Questions
What is a rack PDU?
A rack PDU (rack power distribution unit) is a rack power distribution unit engineered for high-density data center rack power delivery. Positioned at the end of the data center power chain, it receives power from upstream distribution and UPS feeder systems and distributes it to the IT loads inside a standard 19-inch server rack, with configurable outlet and branch protection.
What is the maximum capacity of the K-SPM rack PDU?
A single K-SPM unit provides 90KW capacity within a compact 19-inch form factor, combining high power density with DSP-based precision metering and control.
Can the K-SPM rack PDU be maintained without powering down the rack?
Yes. The hot-swappable switch modules allow individual branch circuits to be replaced without service interruption. Aerospace-grade connectors support live swapping, so faulty modules can be replaced without shutting down the main power input.
How is the K-SPM rack PDU monitored?
DSP-based precision metering and control provide real-time electrical parameter tracking, available over SNMP/RS-485 connectivity for remote monitoring and facility integration, with audible/visual alerts plus SMS and Email notifications.
Where does a rack PDU fit in the data center power chain?
The rack PDU is the last link in the chain. Utility power flows through a UPS and then through distribution assemblies before reaching the IT space: UPS feeder cabinets condition and distribute UPS output, precision distribution cabinets manage final facility-side distribution, remote power panels (RPP) provide row-level distribution, and the rack PDU distributes power to the servers, storage and network equipment inside the rack.
What is the difference between a rack PDU and an RPP?
An RPP (remote power panel) provides monitored row-level distribution with breaker-level visibility between the feeder layer and the rack row, while a rack PDU distributes power inside a single server rack. The rack PDU is the last link in the chain; the RPP operates one layer upstream.
