NFS350 SERIES

Triple and quad output

• Autoranging input

• Ove rvoltage prote ction on main output

• Short circuit prote ction with auto re s tart

• Powe r fail de te ct

• VDE, UL, CSA and BABT approve d

• Floating, fully adjus table fourth output

• 12VDC fan conne ction

• Conducte d nois e to EN55022-A, FCC le ve l B

The NFS350 Series of triple and quad output 350 Watt open frame switchers is

designed for use with larger digital systems. High power density allows a very

compact system design. The advanced topology yields very well regulated outputs

that eliminate the need for inefficient dissipative regulators. The unique floating fourth

output allows a user configurable output voltage, adjustable from 4.5V to 30V, either

positive or negative, at up to 4A. These supplies are approved to UL, CSA, VDE and

BABT and their built-in line filter reduces conducted noise below FCC level B and VDE

0871 level A. NFS350 Series power supplies are suitable for a wide range of general

industrial applications, including process automation, robotics, networking, lighting

systems and telecoms. They are particularly suited for shelf power in miniature rack

systems or subracks.
