Overview
The Sparkle FSP300-601U is a 300-watt industrial-grade ATX12V 1U switching power supply designed for server and embedded systems requiring stable, multi-rail DC outputs in a compact 1U chassis. Built by Sparkle Power Inc., a manufacturer with extensive experience in power supply design, this unit delivers robust performance across multiple voltage rails with integrated thermal protection and efficiency optimization.
Key Features
- 300W Total Power: Sufficient capacity for single-server and embedded computing applications
- ATX12V 2.0 Compliance: Meets industry standard specifications for broad system compatibility
- Active Power Factor Correction (PFC): Improves power draw efficiency and reduces harmonic distortion per EN61000-3-2
- Multi-Rail DC Outputs: Dedicated voltage supplies for CPU, peripherals, and standby circuits
- Compact 1U Mounting: Space-efficient design suitable for rackmount and embedded systems
- Internal 12V DC Cooling Fan: Temperature-regulated thermal management with low-noise operation
- Built-In Protections: Over-voltage, short-circuit, and over-current protection on all outputs
- 100% Hi-pot and Burn-In Tested: Factory-verified electrical safety and reliability
Technical Specifications
Input voltage: 115/230V AC (auto-sensing). Operating temperature range: 0°C to +40°C on full load (storage/shipping: -20°C to +80°C). Operating humidity: 5–95% (non-condensing). Efficiency rated at 68% minimum at nominal AC main. Dielectric withstand voltage: 1800 VAC input to frame ground for 1 second.
