Power-One Inc.’s new FNP850-12 is the first in a series of hot-swap ac-dc front-ends featuring high power densities and I²C-interface capabilities. The FNP850-12 provides 12 Vdc at 71 A, at a power density of 15 W per cubic inch. The front end is designed to power isolated and point-of-load dc-dc converters in networking and storage applications.

The combination of a wide-range input (85 Vac to 264 Vac) with an output adjustment range of 7 Vdc to 12 Vdc enables inventorying just one part number for a variety of applications. Additional applications flexibility is facilitated with a 12 Vdc at 0.5-A standby output, to accommodate startup and I²C operations as required by the host system.

The FNP850-12 has extensive I²C monitoring and control capabilities. Real-time monitoring parameters include ac input, output voltage, output current, and overtemperature. Control functions include fan speed, Enable and output-voltage adjustment. Stored static information includes serial number, part number and location/date of manufacture.

Ultracompact package dimensions, 1.6 in. × 3.3 in. × 11 in. (40.6 mm × 83.8 mm × 279.4 mm) including an internal fan, support use in 1-U and 2-U high mounting configurations. Full-featured five-slot racks providing 4250 W are currently available.

Agency compliances include: UL60950-1, CSA 60950-1-03, EN 60950-1, Class B radiated and conducted EMI, and CE marking to the Low Voltage Directive (LVD). In addition, EN61000-4 EMC susceptibility requirement testing includes ESD (-2), Radiated (-3), Burst (-4), Surge (-5), Conducted (-6), and input interruptions (-11). Pricing is $500 each in quantities of 250.
