G1116-1600WNA – 1600W CRPS Power Supply for High-Power Telecom Systems, Dense Network Appliances, and Modular Edge Platforms
The G1116-1600WNA 1600W CRPS power supply is engineered for high-power telecom systems, dense networking appliances, and modular edge platforms that require stable 54.5V delivery under continuous load. Built in a compact 1U CRPS-standard form factor (185 × 73.5 × 40 mm), it fits seamlessly into high-density chassis environments where power scalability and system uptime are critical. The unit provides a main output of 54.5V at 29.3A, along with a 12V standby rail supporting control boards and management circuitry. Its wide input compatibility (90–264Vac / 180–300Vdc) enables deployment across global AC grids and DC telecom infrastructures, making it suitable for multi-region installations. With PMBus 1.2 integration, the G1116-1600WNA supports digital monitoring, fault reporting, and remote adjustability—enhancing operational insight and power optimization. Platinum-level efficiency ensures minimized waste heat and predictable performance in long-duration workloads. Smart fan modulation improves cooling efficiency while keeping acoustic noise controlled, even in heavily populated rack environments. The hot-swappable CRPS design helps maintain uninterrupted service, enabling quick replacements without system downtime.

Deployment Scenarios
The G1116-1600WNA stands at the extreme performance level of the G1116 series, delivering 1600W continuous output for compute infrastructures where concurrent virtual workloads, GPU participation, and storage synchronization run at high duty for extended periods. This power tier is suited for dense VM fabrics, AI inference-enabled clusters, NVMe caching cores, hybrid compute gateways, and metropolitan POP server blocks where high compute concentration must remain stable without rail fluctuation. Compared to the 1200W model, the 1600W tier provides additional voltage stability when multiple service demands peak simultaneously, limiting thermal throttling risk and maintaining low-latency response in real-time load scenarios.

Power Architecture & Reliability Design
The G1116-1600WNA leverages a strengthened power conversion structure engineered for multi-accelerator workloads, synchronized virtual machine migrations, and long-running storage pipelines. Its electrical design prioritizes stable 12V delivery under high concurrency, ensuring predictable behavior when compute acceleration, virtualization, and I/O-intensive processes overlap during peak operational windows.
Ripple suppression and EMI treatment are carefully tuned to preserve signal integrity across PCIe, NVMe, and network fabrics during heavy transaction activity, such as sustained rebuild operations, encoding tasks, or burst-driven data movement. This controlled electrical response minimizes the risk of performance jitter or link instability that can arise when multiple subsystems draw power simultaneously under tight timing constraints.
Thermal zoning is designed to maintain consistent airflow through dense chassis layouts, mitigating heat saturation during multi-hour compute cycles and extended high-duty operation. Integrated PMBus telemetry provides operators with visibility into power curves, thermal behavior, load distribution, and fan duty ramp patterns, enabling data-driven reliability planning across large fleets of identical nodes. As the upper tier of the G1116 platform, the G1116-1600WNA is well suited for data centers that demand sustained performance, operational consistency, and long-term stability at scale.
