G1116-1200WNA – 1200W CRPS Power Supply for Carrier-Grade Networking, Telecom Edge, and Compact Data Systems
The G1116-1200WNA 1200W CRPS power supply is built for carrier-grade networking gear, telecom edge platforms, and compact data systems requiring high-efficiency and stable 54.5V output performance. Its 1U CRPS-standard form factor (185 × 73.5 × 40 mm) enables smooth integration into dense modular frames and multi-node system architectures. This unit delivers a main output of 54.5V at 22A, with an additional 12V standby rail supporting system control logic and embedded management modules. The wide input range (90–264Vac / 180–300Vdc) ensures compatibility with global AC grids and telecom DC infrastructures, making it suitable for multi-region deployments and hybrid power environments. With PMBus 1.2 support, the power supply offers digital control, detailed telemetry, and remote supervision to optimize system reliability and operational insight. Its Platinum-level efficiency reduces energy loss and thermal stress during sustained workloads. Intelligent fan control provides adaptive cooling while maintaining reduced acoustic levels in mixed-load operating conditions. Combined with the hot-swappable CRPS design, the G1116-1200WNA helps maintain continuous service uptime in mission-critical installations.

Deployment Scenarios
The G1116-1200WNA steps into the high-power category of the G1116 series, delivering 1200W continuous output for workloads that extend beyond standard virtual machine density and move toward GPU-participating compute or heavy storage synchronization. This tier is ideal for regional compute clusters, inference-assisted application servers, SDS/NVMe arrays, CDN mid-layer nodes, and office datacenter expansions where power demand is elevated and burst behavior may be frequent. Compared to 0900W, the 1200W model offers greater resilience under parallel VM scaling, cache rebuild operations, and AI pre-processing, maintaining output stability when demand surges occur across containers and services simultaneously.

Power Architecture & Reliability Design
The G1116-1200WNA adopts a reinforced power conversion architecture designed to preserve output quality during I/O surge cycles, inference trigger events, and batched virtual machine orchestration. Its electrical regulation remains stable as storage, compute, and network demands overlap, allowing the system to absorb short-term spikes without rail distortion or recovery delay.
Ripple suppression and EMI filtering protect data paths during NVMe flush operations, replication storms, and caching activity, helping maintain predictable behavior across PCIe and storage fabrics. Thermal zoning is structured to distribute heat evenly during multi-hour sustained workloads, reducing temperature cycling stress and supporting reliable operation under continuous duty.
This design targets regional workloads deployed in POP racks and mid-sized data centers where cooling conditions may vary but uptime expectations remain high. PMBus monitoring provides visibility into thermal drift, fan response, and load evolution over time, enabling planned lifecycle replacement and proactive maintenance across fleet-scale deployments. As a result, the G1116-1200WNA offers a balanced step up in concurrency handling and long-run stability within the G1116 platform.
