NFS350 SERIES Triple and quad output • • • • • • • • [ 2 YEAR WARRANTY ] SPECIFICATION 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.

Total peak power may not exceed 450W. 2 Forced air, 30 CFM at 1 atmosphere or 350LFM. 3 Figure is peak-to-peak. Output noise measurements are made across a 50MHz bandwidth using a 12” twisted pair terminated with a 47µF capacitor. 4 Total regulation is defined as the static output regulation at 25°C, including initial tolerance, line voltage within stated limits, load currents within stated limits, and output voltages adjusted to their factory settings. 5 Floating output can be adjusted from 4.5V to 16.5V and referenced as either positive or negative. 6 Floating output can be adjusted from 15V to 30V and referenced as either positive or negative. 7 Output shorts will cause all outputs to fold back, protecting the supply from damage. An overvoltage or overtemperature condition will trip the output crowbar, shorting the outputs and also cause foldback. When the fault condition is cleared, the supply will automatically recover. This supply can be configured to latch off in the event of any output short. Disconnecting line power for 15 seconds will reset the latch. See mechanical note B. 8 Derating curve is application specific for ambient temperatures > 50°C, for optimum reliability no part of the heatsink should exceed 90oC and no semiconductor case temperature should exceed 100oC. 9 Caution: Allow a minimum of 1 second after disconnecting the power when making thermal measurements. 10 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product.
