This FSP250-2F47-A54H is an AC-DC switching power supply from FSP Technology Inc., designed for reliability and performance in demanding applications. It features an open frame, chassis mount design, making it suitable for integration into various systems.
The power supply offers dual outputs of +12V and +54V, delivering a continuous 250 watts of power with forced air cooling or 190 watts at convection cooling. It operates over a wide input voltage range of 90-264 VAC and features a power factor of 0.98 minimum at 115 VAC. Key electrical specifications include a minimum efficiency of 89%, a hold-up time of 12 ms, and line regulation of ±0.5% maximum.
Protection features include over-voltage, short circuit, and over-temperature protection, all with auto-recovery. The operating temperature range is -20℃ to +70℃, with derating above +50℃. Environmental compliance includes RoHS3, REACH Unaffected, and MSL 1 status.
Designed for applications such as PoE switches, network, and telecommunication equipment, this power supply meets EN 55032 and FCC Class B standards for EMC performance. It also includes features like low inrush current and high altitude operation up to 5000 meters.
The input voltage range is 90-264 VAC.
The converter provides +12V at 4.2A and +54V at 4.2A.
