3RAMAP044300 IN WIN Development Active 1600W 1U PSU

High-Efficiency 1U Redundant AC Power Supply Module for rack servers with the 3RAMAP044300

The 3RAMAP044300 is a 1U redundant AC PSU module engineered to restore or expand the power budget of enterprise rack servers while maintaining N+1 service continuity. Designed for 100–240VAC wide-range input, it stabilises the server power domain under variable facility conditions and supports datacentre standard power distribution without requalification of the upstream feed.

With 1600W capacity and 80 PLUS Platinum efficiency, the 3RAMAP044300 targets lower conversion losses and reduced thermal load at the chassis level, which improves fan curves and overall platform acoustics and reliability. Its modular implementation aligns with hot-serviceable redundant PSU bays commonly found in 1U platforms, enabling maintenance windows to be shortened and capacity uplifts to be executed without redesigning the compute node. Integrated protection functions including OVP, OCP, SCP, and OTP help isolate power anomalies before they propagate to CPU, memory, PCIe endpoints, and storage backplanes, supporting predictable operation across mixed workload profiles.

Why Choose the 3RAMAP044300?

The 3RAMAP044300 provides a practical density-to-availability upgrade path for 1U servers that must sustain performance under consolidation. By pairing high efficiency with redundant-capable architecture and active cooling, it supports scalable deployments where power headroom, serviceability, and fault containment are prioritised across clustered racks and edge-to-core footprints.

IN WIN Development focuses on mechanically consistent modules and electrically robust power conversion designed for continuous operation. The 3RAMAP044300 reflects an engineering approach aligned with modern data centre expectations for high-efficiency power delivery, controlled thermals, and repeatable maintenance processes.

Key Applications:

• 1U rack server PSU replacement and lifecycle refresh
• Redundant power subsystem upgrades in clustered environments
• High-efficiency power delivery for virtualisation hosts
• Datacentre nodes supporting NVMe storage and PCIe expansion
