NFS40 and NFN40 SERIES Single and triple output • • • • • • • • 5.0 x 3.0 x 1.2 inch package (1U applications) Industry standard package Overvoltage and short circuit protection 40W with free air convection Fixed frequency operation (NFN Series) NFS40: EN55022, EN55011 conducted emissions level A NFN40: EN55022, EN55011 conducted emissions level B UL, VDE and CSA safety approvals [ 2 YEAR WARRANTY ] The NFS40 and NFN40 are industry standard 40 Watt power supplies with the capability to supply 50W in a forced air ambient and to automatically operate from any voltage between 85VAC and 264VAC. Use of MOSFET based switching circuits allows for enhanced features such as output regulation down to zero load (NFN40). Universal input voltage eliminates the need to change jumpers or switch settings to cater for different or widely varying line voltages. In addition to the input voltage range, VDE, UL, CSA, EN60950 and IEC950 approvals make the NFS40 and NFN40 ideal for use in equipment installed throughout the world. The fixed frequency operation of the NFN40 further reduces emissions below VDE class B and significantly reduces leakage current. These low profile switchers with high power density are intended for use in small, digital systems.

Peak output current lasting less than 30 seconds with duty cycle less than 10%. During peak loading, outputs may go outside of total regulation limits. Peak total power must not exceed 60W. Forced air, 20 CFM at 1 atmosphere, 50W maximum. Figure is peak-to-peak. Output noise is measured across a 50MHz bandwidth using a 12 inch twisted pair, terminated with a 47µF capacitor. 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.
