Product Description
This compact 400 W FLEX power supply is designed for industrial, automation, and small-form-factor applications, offering efficient and reliable power delivery in constrained spaces. Key Features Wide input range (90-264 VAC) with full-range compatibility Comprehensive protection: over-voltage, over-current, short-circuit, over-temperature High MTBF and 100% burn-in testing for robust performance Multiple high-current outputs (+3.3 V, +5 V, +12 V, -12 V, +5 VSB) tailored for server/automation gear Internal 4 cm fan ensures quiet cooling in dense environments Ideal for embedded servers, 1U chassis, NAS units, or industrial controllers, this PSU excels in scenarios demanding space-efficient, low-noise, and highly reliable power. It's particularly suited to environments with continuous operation and variable input conditions.

Use Cases
The FSP400-50FDB Sparkle 400W 80 PLUS Gold FLEX power supply is designed for industrial and embedded systems that demand reliable, efficient power within constrained spaces. It is particularly suited for IT professionals and system integrators working with compact server appliances, network-attached storage (NAS) devices, and automation control units where stable power delivery and low noise are critical. How It's Used: Powering compact rack-mounted servers in remote office or branch office (ROBO) environments requiring high energy efficiency. Supplying consistent power to NAS clusters used in small to medium business (SMB) storage networks for data redundancy and backup. Integrating into industrial automation controllers and embedded systems operating in manufacturing or process control settings. Supporting virtualization edge nodes where tight space constraints and reliable low-noise operation are essential. Deploying in telecommunications equipment racks to maintain uptime and reduce overall power consumption in network infrastructure. This power supply module enhances operational efficiency by delivering stable, high-quality power in a minimal footprint, enabling scalable deployment in space-limited or noise-sensitive environments. Its tailored design supports continuous operation under demanding workloads, benefiting IT infrastructure that prioritizes reliability and performance.
