FSP350 F35 A Series Applications

FSP350-F35-A Series: Compact 350W Open Frame Power Supply for Flexible System Integration

The FSP350-F35-A Series combines up to 350 W continuous output with a compact 3 × 5 × 1.34-inch Class I design. It is suitable for networking, PoE, display, information, and audio and video equipment. The series delivers 200 W with convection cooling or 350 W with 16.8 CFM forced-air cooling, with four DC output options, up to 94% efficiency, and no-load power consumption below 0.5 W.

High Power Density in a Space-Saving 3 × 5-Inch Design

The FSP350-F35-A Series delivers 350 W continuous output within a low-profile 3 × 5 × 1.34-inch footprint, supporting high-power systems with limited installation space. Without forced airflow, it provides 200 W continuous output through convection cooling.

The LLC architecture and isolated 12 V fan driver support cooling integration. The operating temperature range is -20°C to 70°C, while the storage temperature range is -40°C to 85°C. Operation at altitudes of up to 5,000 m is also supported.

Flexible Output Voltages for Different System Designs

Output options of 12 V, 18 V, 24 V, and 54 V DC provide wider voltage coverage for different load and system requirements. High efficiency of up to 94% helps reduce conversion losses, while support for a 0 A minimum load allows operation without a defined minimum-load requirement. No-load power consumption remains below 0.5 W.

Safety and EMC Compliance for System Integration

The Class I design of the FSP350-F35-A Series conforms to IEC 60950-1 and IEC 62368-1 safety standards. It is also designed to meet EN 55032 Class B radiated emissions and EN 55024 electromagnetic compatibility requirements, supporting safety and EMC planning during system integration.

FSP Power Solution provides custom and semi-custom support for projects with additional electrical, mechanical, or certification requirements.
