[ 2 YEAR WARRANTY ]
NFS350 SERIES
Triple and quad output
• Autoranging input
• Overvoltage protection on main output
• Short circuit protection with auto restart
• Power fail detect
• VDE, UL, CSA and BABT approved
• Floating, fully adjustable fourth output
• 12VDC fan connection
• Conducted noise to EN55022-A, FCC level 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.
